Geiger counter add on - Hardware Hacking General

Hi if someone could translate the instructions on this page:
http://www.radiation-watch.org/p/assembly-manual.html#sec7
into english it would make a pretty cool addon.
Thanks

FTFY! (Need 10 characters to answer you)

search the market for com.rdklein.radioactivity
its a geiger counter based on your camera taped off and it seems pretty legit and amazing
check the website too
hotray-info.de
luckily i couldn't really test it yet

I was looking forward to testing this until I realized they want five bucks for it. Also judging by the reviews I would say it's either a scam or it just wouldn't work with my phone anyways, someone else with an Evo 3D put on there that it didn't pick up anything from a radium watch or a stack thorium welding rods.

How can the camera pick up radio active particals to make a Geiger counter? When the cmos is only designed to pick up emf (electro magnetic frequency) in the human visual spectrum? OK given that most cmos camera devices will stretch a little bit outside the normal human spectrum up to infrared but not much more than that, radio active particals are not within the visual emf of humans...

This is because that radioactive particles are much higher energy and will act on the CMOS detector. It works by figuring out what the noise pattern on your camera is then it just looks for spikes in pixels or groups of pixels and maps those are radiation. There are some fudge factors to convert from pixels and stuff to actual radiation numbers.

So does your camera have to be active for this to work? Or can it work passively?

The sensor will need to be open (active).
Keep in mind that it'll be somewhat useful to detect the presence of radiation, but absolutely useless for quantifying it. It'll also be quite insensitive.
If you're after a dose rate (quantifying) meter, you'd be better served by a serial-connected counter. If you're just mucking around though, the camera-based one may suffice

It's somewhat similar to the pulse detector apps for phones... Cool to play with, and lets you say "oh my heart rate is faster after I did my run"... But while it's relatively accurate, you'd want a real monitor for any serious usage... Or take the pulse manually
I guess similar applies here. The dosage depends on the amount of radiation emitted, not how much manages to "light up" the Cmos above background noise...
Again, cool to point at rock which is slightly above background levels, but no something you want to rely on.

Oh just thought of something, the sample rate of the sensor would effect the readings wouldn't it?

The "REAL RadioactivityCounter" made by scientist Rolf-Dieter Klein, is indeed a very serious competitor. The mere fact that someone has bothered to work out the details how to make a cheap mobile cam, detect ionizing radiation, deserves a PhD by it self.
The difference in using your phone with taped over cam, costing you $5 bucks, is nothing compared to buying a dedicated device in the $100+ range, that is only slightly better for certain types of short-range radiation like (alpha and low-energy beta). In addition the cam CMOS sensors doesn't saturate under high doses, like an ionization based device, and thus provides better accuracy!
The sensitivity depends on the physics of your mobile camera, where most phone cams start picking up radiation at about 10 µSv/h. For the iPad2 it picks up radiation already at the 1 µSv/h level.

So unless you are making high-precision, low-energy or background radiation measurements (like looking for Radon in houses), this app is worth every penny. In addition it is one of the best supported apps out there, with a solid scientific base.

I especially like the radioactive Bavarian mushrooms YouTube video!

Would this be sensitive enough to detect leakage outside of x-ray rooms ? Yes, I realize that is is not a substitute for the devices used by licensed radiation safety expert.

Probably not, since "leakage" measurements involve low level (and possibly also low energy) detection, under a long time.

It works

It appears the Evo 3D is on their site of devices it works with, so maybe that was just a garbage review after all? It would be nice if there was a trial version for it, I have some Cd-109 and Sr-90 sources I'd like to test it with.
You would think the optics would block nearly all of it, but they say some cameras can still pick up beta particles (Sr-90 specifically). If so this may be useful in finding pitchblende.

Again it depend on the construction and location of the camera module. This is also the reason why they prefer to use the front facing camera for this. It simply contains less lenses and simpler electronics, that can complicate proper measurements. According to the developer, measuring pitchblende is working really well!

Not necessarily... any good heart rate monitoring app works completely perfectly. Maybe you have a bad camera/flash position or the app can't count. It's exactly the same as a pulse ox that they use in hospitals, no reason it'd be any less accurate. If you don't believe me go break into an ER and measure with both

Full Review of Atrix 4G

Hey all!
I've posted my full review of the Motorola Atrix 4G. Overall, I think it's a solid phone.
I compared it to the Samsung Captivate specifically, but also talked about HDMI-out, GPS performance, battery life, speed, etc.

Nice review!
I'm really looking forward to upgrading to this phone when it launches in the UK
I'm sure I read a review a while ago that implied that, when using the multimedia dock, it was possible to wirekesslt stream media from locally networked storage. but I cannot find it now
is there any way you could test this?

Unfortunately, I don't have a WiFi network to test it over (I'm connected via LAN) on video.
However, I have already tried out this feature, called DLNA, and it works seamlessly with Windows Media Player. You simply set up a shared playlist in Windows Media Player and then click on the DLNA application on your Atrix while connected to the same WiFi network as the server (computer).
It works well. My only gripe is that the Atrix cannot play back .MKV files.
@Stunno
I found a stray WiFi network to use. Obviously, my computer wasn't connected, so I can't set up a playlist to stream.
But I took a screenshot of the DLNA application. Overall, fairly easy to set up.

Great stuff! Thanks for the reply, Kenneth! It's very much appreciated, any thoughts on whether it could access samba shares?
I have a TV upstairs in the bedroom, and rather than run an aerial wire to it I was going to buy something like a Revo and set up media streaming (I have a couple of TBs of DVD rips on a NAS) Then I saw the Atrix + multimedia dock and it all became so clear

Hmm. I'm not too familiar with Samba. Here's an official Motorola rundown of DLNA on the Atrix 4G:
https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/60673/p_country_code/US
Thanks again!
From the list on http://www.dlna.org/ it looks like my NAS is supported by DLNA, so, hopefully, I should be good to go!!
Now we just need Motorol;a to get their fingers out and release it over here!
Many thanks again Kenneth!

Many of the folks here are seeing average to below performance with the battery. But you have rated it as exceptional. Can you provide more details on your usage during those 16 hrs?
Nearly every topic you listed had negatives for the phone but you say its a solid device? Id give it 2/5 stars at best. Really disappointed.
The screen is horrible - cant even display yellow properly. Not to mention its pixelated and washed out.
Battery life is abysmal.
Really the only thing I found "good" with this phone, was the call quality.

Im quite sure the color issue is software related. This phone was rushed out the door, lets not forget. I also think the camera could be optimized better through software also. This phone is just an infant. If we can get some custom roms on it the future is sky high for this phone. Right now it feels like a beta.
I read your review and while it was thorough I do have one criticism, and it can be levied against pretty much anyone who has used an AMOLED device prior to the Atrix.
Everyone falls prey to the "Ohh shiny!" problem of the AMOLED screen. Oversaturated color is NOT accurate color. It's just like in big box retailers where they crank up the contrast and backlighting to make TVs "pop". My Blu-Ray player even has a "store" mode in the settings menu that turns on different lights and displays that aren't normally running just to draw your attention. If you had it setup that way at home you'd go insane (not to mention not being able to sleep from the light in the room). Just because it's bright and shiny does not mean that it's at all representative of the real world, and the average person just doesn't understand that.
Also, the picture you used in the screen portion of your review comparing the two phones has to do much more with the different screens' viewing angles than their perceived color reproduction accuracy.

I usually use the device every other minute while I'm in classes or at work. I surf the net, usually visiting my blog and other tech blogs. Then I check out Analytics applications. I also watched a full episode of The Daily Show during my test... which was the biggest drain (Flash over browser). I don't know how anyone could say battery life was terrible. Battery life on this device matches my iPhone... and it's better than the battery life on any of my past Android devices.

It might seem like every category was negative, because I was trying to be critical of the device and point out its flaws. You must remember that all of the categories are weighted more than others. Speed and processing power is more important than the lack of video codecs... for example.

Have you used the device? You really believe it feels beta? I'm pretty shocked to hear that. This thing is incredibly fast, efficient, and sleek. I'm loving it so far.

This is partly true. Over-saturated colors aren't accurate. It is also true that the angle of the picture makes the Atrix's colors look worse.
I did that angle for a reason. It was the only way that I could show how the two screens look side by side in true life. Every other time, the camera would balance the colors and the Atrix would look equal with the Captivate. The picture under the screen section is actually a very accurate view of the comparison between the two screens.

I understand the reason but it really provides a skewed view of the phone which is unfortunately a common problem in the media.
You must have a very sophisticated camera for it to compensate for different colors in different areas of an image. Mine (Canon Powershot S90) is only capable of adjusting white balance or hue/saturation/brightness/contrast over the whole of the image.

Canon Rebel T21. It's a friend's.
Not sure if it was balancing colors or if my lighting was just poor, but it wasn't communicating the major color difference when I took a straight shot.
I did include a straight shot with screens on in the gallery of pictures within the review FYI.
But, the color difference is much more dramatic in real life. Whites look more accurate on the Atrix. Other than that, blacks and ROYGBIV look way better on the Super AMOLED.
However, I would still buy this phone over the Captivate any day. The screen is still wonderful... and the resolution is useful.

Galaxy S II

Hi, I was an andorid user and when i had one i loved it too bits then came windows phone 7 and im not going to lie i loved that more, however I am due a upgrade and the sheer power of the new andorid phones overpower windows phone 7 handsets and adter watching some youtube videos web browising is faster. However I have a few questions, would you recommened it? How is the batter life with e-mail updates constant/instant and few web browsing. My old android x8 had soem lag, has this now been sorted due to the power or is it jsut andorid os?
Thanks
Here's some things to consider with the SGS2. Some of what's listed effects different users to different degrees.
- Display
There's a band on the left side that seems discolored on a gray background at 20% brightness in the dark. Some see it in everyday use, some don't. I'd venture a guess that more don't or the hue and cry would be louder. If you're anal retentive about your display, check out the 60 page thread.
- Wi-Fi
Seems wonky for some users. It may be equipment specific (EG: router) or strangeness with a particular handset. There's a couple of threads running on that.
- 2G/3G/4G
There's some connectivity issues depending on what network you're on. Make sure your location and/or carrier aren't ones people may be having issues with.
- Audio
If you're an audiophile there's a couple of threads on audio performance which, due to a number of factors, has been deemed by pros to be below that of the original Galaxy.
- Camera
There's a bunch of threads on stills and video. Read them if you're a heavy camera user. Biggest issue now is a pink spot showing up photographing white backgrounds in natural light.
- Battery
Average at best. As things currently are, plan on 10-16 hours depending on how you use the phone. There's an issue in 2.3.3. that effects dual-core phones and Samsung's issuing an update to 2.3.4. any day now which is supposed to correct it.
Based on the way I (and only I) use the phone I'm very happy and the above issues either don't bother me or don't effect me. The phone's fast, the display is beautiful, and it's a great all around device. Compare your hot buttons to those of others and if you think you're good, by all means get the phone.
Don't forget the color banding, gradients don't appear smooth but look banded like they did in the 90's with 16 bit color

There's a thread on whether the phone's fully using its 24bit capabilities via the display. The theory is that when software is directly addressing the screen its fine. When drivers get involved it drops to 16bit. The same thing happened to the Nexus S and was fixed in 2.3.4. We're hoping the same thing happens.
I would just like to that all you for your comments, so far all the problems are actully scaring me lol. However with all these problems would you still reccommened this phone? If so do you like it more than your previous andorid phone?

Look, if your just using it as a device that can phone, text, take pics when you need that arent for a magazine or something, play some tunes whilst you are on the bus or whatever, do some modding if you are that way inclined then buy it. If you are fussy about anything like that find something else. People will always find problems with devices like this as they are used to better maybe or compare it to a device thats is specifically for playing music or taking photos. This is a great phone, best i have had and i am well pleased. Just my opinion anyway.
Im so tired of people summing up everyones experience. I have a sgs2 from first batch and I have none of the problems youll find on the first 2-3 pages of threads. Remember like the member above me said, people with complaint threads will post before a postive thread. Complaint threads will get the most attention and see the most post. There might be less then 10 members actually having the problem if you read through the thread.
Display: gradients on screen is really only not that noticable unless your anal. Only time I see it is when I open xda app(takes ages to load on brown screen) and others are seeing it on the intro to angry birds. Not while actually playing but the intro lol. Screen is beautiful and works 99.9% correctly.
Wifi: I have no issues with connection or speed. I download lost of big files daily. Mostly mixtapes and other files usually around a 100mb+. I get connection and my 15-20mbs download no matter where im at in my house.
2g/3g/4g/ My device stays connected through 3g all day. When im actually downloading or using data it switches in 1sec to H+. Real world usage is really fast in North florida but if im playing with speedtest apps I will get mixed reviews.
Audio- I start my music at work around 9am everyday. I work with loud ass dogs and other various animals on a daily basis. Never had a problem with audio coming through my handset and I use the included headphones. At 50% I can hear my audio over barking dogs. In my vehicle with my 2 12s and 1000w amp you can hear me from a block away. Easily matches my wifes iphone4 if not better with poweramps eq.
Camera- No issues here. Just getting back from short trips to jacksonville fl, orlando, and north georgia(mostly ATL) and no pink spots on my photos.
Battery life is all user to user. I myself have the luxury of charging my phone over night unlike others on the website. I can do my heavy using from 9-6 everyday and still have 30-50% when I get home. Music is always playing through headphones(9-6) 2 emails checking hourly, check xda 1000times, browse atleast 20 websites throughout the day and other numerous stuff and can make it home after a work day. If I was anal I could get 2days out of my phone before it actually dies. Remember with android most problems are User Error.
Unless you are in love with Sense, theres no phone that can match it until the next sgs comes out.

Do you think this is a normal IQ for a High End device like the S2?
As to Angry Birds 1 & Rio (and other games too) it is not only noticable in the intros my friend ... if you play them you will see !
Yeah I consider that not noticable in my book.
1st photo is a picture of the battery charging when phone is turned off if I'm correct. I don't stare at my screen when its just charging. In my real world use ill never see that long enough to annoy me.
2nd pic is when its connected to kies. When I actually use keis I'm not looking at the phone. I'm not saying its not there but the first 2 pics is not something I see daily. Im guessing the 3rd is a game but I don't play it. But the gradient is there.
I'm pretty sure I've heard its a software issue and not hardware. I find the pictures you posted funny. It shows me how hard it is to reproduce the gradients. But like I've said before I must have crap standards to accept a phone with imperfections. Can't believe I spent 700 on the best phone out to date.
To me this is a small issue that's resolved with a software update or one of the amazing devs come up with something. We don't have a ton of choices and I rather have gradients on a FEW screens vs what HTC is doing.
I understand that im a early adaptor of a device. Things may be changed/fixed in the next couple of months like nfc or something.

[RADIATION] Note 1 vs 2 vs 3, CNET+Samsung Official Results

Introductory:
Hello all, cell phones produce radiation just in case you did not know. These radiation levels are measured in a value called SAR(Specific Absorbtion Rate) and it literally is the measurement of just the bottom line of what the human body absorbs, rather than just the amount that it radiating(ha, get it?) around the device. Radiation is bad in the human body where it is directly related to certain issues, including directly reducing bone density in the body. I am posting this as an accurate informational thread where you can draw your own conclusions based off of facts.
SAR Levels:
SAR, which stands for Specific Absorbtion Rate, levels fluctuate depending on numerous factors, in which we must go over in order to accurately understand. The key thing to understand is that the further the device is from your body, the levels begin to diminish by the milimeter(mm).
For a phone to receive an FCC certification, the device cannot have a SAR level of more than 1.6 watts per kilogram in the US, and 2.0 in Europe.
Galaxy Note Series Tests by Samsung:
Let's take a look at the Note series in order to keep this sequential and easier to remember from a timeline fashion of perspective. The Galaxy Note 1 was released first(obviously) and is the model number SGH-I717 for reference. Taken from Samsung's website directly, here are the Note 1 results, including the way that they perform their own measurements:

}
You can see in this writing the methods that are used for testing, and that the body specific SAR tests have the device at 1.0 centimeters(CM), equivalent to 10 millimeters(mm) away. Keep this in mind and we'll touch up on this later.
And here are the Note 2 specific values:
And here are the Note 3 specific values:
So as you can see the comparisons above, the Note 3 effectively produces 153% more Head SAR than the Note 2, and 196% more Head SAR than the Note 1!
I would calculate the Body SAR differences but we have a big problem with Samsung's specific tests...they test these values with the device 1.0 CM(or 10mm) away from the body. This Body SAR calculation is useless to you if your phone presses against your body at 0 mm away!
Let's think...why would Samsung measure in this fashion at 1.0 CM away? Well the Note 3 produces 1.28 Body SAR at 1.0 cm away, so the big question is what would it produce at 0 mm away/ AKA in your pants pocket? Maybe it would exceed the FCC limitation of 1.6?
CNET Testing:
Now let's take a look at a recent test performed by CNET on 1/16/14 to see what they have found in differences in the Note series in particular:
The above is literally all of the information they posted where it is tough to tell how the test was performed and/or what body part it was performed against. By comparing the numbers, it seems as though they tested the head only since it matches the Head SAR values by Samsung.
But there is only but one main discrepency...the Note 3 reads 0.63 SAR value by Samsung, while CNET tested it at 0.9 SAR. Which one holds true?
Device Model Top Charts:
As you can see in the following results, our devices do not hold the highest SAR values compared to the worst out there *ehem* Motorola!
And here are the lowest SAR values amonst all devices. Keep in mind how the Note 2 is 4th lowest.
Theorycrafting:
I researched more into studies being performed per the distance of an object from humans and have found some interesting results.
Here is a model of the human head for reference, spefical model for SAR testing:
And here is are one test's results from testing the SAR levels after altering different distances:
This is just me tipping the iceberg to not go on and on.
Shifting gears toward current events, check out 2/14/14's event of the Army buying 7,000 Note 2's for its troops HERE
The reason why I feel that this is relevant is that they definitely would not want to have their troops being exposed to radiation levels higher than other devices. What makes more sense though is that they tested it for quite some time before it was rolled out, but who knows?
General Radiation Reduction Techniques:
-Consider a cell phone radiation reduction case, Google Pong research to get started since I'm probably not allowed to post links
-Consider buying a device with low SAR levels
-Keep the device out of your pocket or anywhere where it is directly against your skin. Even a hip holster might help keep it a few cm away, or carry it in a purse/backpack.
-Use speakerphone as often as possible to keep the device far from your head.
-Devices use the most radiation when beggining and ending calls. Pull the phone away from your head, even if just a few centimeters, when beginning and ending calls.
-Devices also use high radiation when "hunting for a signal". This occurs when your device has no signal, and needs to omit more power consistently to find one. So keep it away at these times.
-Bluetooth uses less radiation, but overall can be more damage from keeping it on your head for long periods of time. LOSE THE BLUETOOTH!
-Text instead of calling whenever it is applicable/feasible
-Don't sleep with the device near your head....think about it, 6+ hours of it so close to your head...
-Last things I wanted to mention are beefing up on certain things you eat.
a.) Eat seaweed, it's very powerful against radiation
b.) Look for natural supplements that particularly repair already damaged cells in your body from radiation. They are alpha lipoic acid and vitamins C and E...BUT ONLY IF YOU DON'T GET THESE FROM NATURAL DIET
Conclusion:
Considering all of the above along with knowing that we are the guinea pigs for long term cell phone radiation, I strongly feel that it's best to consider SAR levels when purchasing a device. The SAR levels are obviously increasing with each new model being released and should be monitored closely.
It seems to show as being a factor toward brain tumors and bone density loss in only 1 of 2 legs in people(where they always kept their cell phone in the same pocket). I did not go much into detail here about these particular researches/tests, but I would recommend to now start looking into the tests performed for "decade-long cell phone radiation exposures". Imagine us after 50 years of exposure, and please feel free to comment here.
Your voice and opinions matter in this world, and you should speak up since you have a right to your own opinions, and I will respect it no matter what. While I don't really know the true effects of the radiation, my opinion is that I'm open minded so I'll keep the cell away from my body to be safe. I will post this across multiple forums that it belongs in and moderators, please let me know if I happen to post this in a forbidden section. Don't censor truth, and let the thread live.
Thank you for your time reading all of this and I hope it helps. If so, please rate the thread 5 stars and hit Thanks solely to promote the spreading of the word.
I'm sure that all this info is helpful, but I personally just don't think about, or actually care about it. When choosing a phone, I am concerned about features and price. If I start thinking about it, then I'd have to also think about how much radiation my appliances in the home put out, how much emissions my car puts out, and the amount of everything in my food & water. Have you looked under a microscope at a drop of water? That alone would make you think twice about drinking water ever again. Or how about the acceptable levels of feces, hair and toxins allowable in food products.
I'm not condemning nor criticizing your research. I actually thank you for the effort you put into it to bring awareness to us. It's just, as for me, I don't think about or worry about, such things.

I hear you, I'm kinda the opposite where I consider the things I put into my body. For water like you mentioned, I filter my own water with a Berkey rather than tap/bottled water...and don't use a microwave(Pizazz pizza maker instead)
hopefully this sar radiation is like gamma radiation then a few of us can turn into the HULK and HULK smash AT&t for not updating us on time and locking the bootloader.
Of all the things likely to kill or injure me I'd put my wireless devices in the bottom 5%. And while radiation levels may have gone up over time the amount of time we actually hold our wireless devices to our heads has gone down with the percentage of voice calls decreasing in favor of other functions.

Aggressive Method to prevent throating on Stock ROM (Fan)

Ive been so sick of how poorly LG handles software heat management that I decided to create a portable yet practical fan heatsink case for my G3. At the time I didn't want to load any custom ROMs and then mess with the Kernal in order to solve the overheating throating issues we all face with the Stock G3 at some point.
Supplies = Aluminium Foil, Double sided tape, 40mm fan
Heres how I did it with spending less than $10:

}
Take a look at the red areas in the picture above, These are the areas (that I believe) are where most of the G3s heat is accumulated.
-I took at least 5 sheets of paper size aluminium foil and I folded and compressed them into a poor man's heatsink about the size of those red areas in the picture.
- After that I was able to snap on the normal backcover with the help of some double sided tape
- Then I put some thermal compound (optional) onto the back cover near the red areas
- Applied 2-3 layers of aluminium foil on top of the thermal compound (or double sided tape)
-Stuck the 40mm on the back cover.
Done, the fan never gets in the way and allows my temps to remain a tad lower.
Let me know if anyone found this interesting so ill post some pics.
Have you tried the CTT MOD (Custom Thermal Throttling)? You have to have ROOT+TWRP installed but it does wonders.
You should definitely try it if throttling really bothers you.
Not sure how effective it is but definitely impressive.
post some pics, thermal compound from pc its ok to the smarphones?
i'd really like to see some pics. this sounds like a great DIY idea for me.
A for effort but this makes no sense . i put in a copper shim and the back never gets hot anymore . all the heat goes to the frame .
Definitely seems rather, coutner intuitive if you ask me.... I can understand putting some sort of 'heat sink' there if it was thin enough, but adding a fan??? That... just completely takes away any and all point to have the phoen be 'slim'. it wont work in 'cases' anymore without cutting a giant hole in the case. It wont fit in some (key word there) docks/car docks. It'll make the phone have a constant 'fan noise' unless you did some magical software tweak that only makes the fan turn on once it hits a certain internal temp... But I doubt that was done. Yea, sure, keeping the phone cool should be a good thing, but this just sounds like one hell of a horrible way to go about it. I do think its awesome that you managed to do it, and it is definitely an interesting way to go about it, but from a practical standpoint, its just obtrusive and inefficient.. As a previous commentor stated, just slip a piece of thin copper or something there and presto, problem solved.
And yea, I'm definitely with you there about the whole 'LG needs to stop being lazy with thermal issues' stuff. I've used many roms in the past with my G3, and I ONLY have a 'heat problem' whenever using roms that are 'close to stock'... which is very annoying... But, most of the time when I'm experiencing such thermal issues, is when I'm in the car and using Torque and Google Maps at the same time. But this is negated thanks to my car's A/C. I just spin the air duct around to face upwards and it blows directly onto the phone and the dock, cooling the phone down considerably.
awesome, ill post some pics once I get a hold of a camera that's not my phone .
My heatsink design, is definitely inefficient, if I had the time and money, I would definitely use better materials. At the time I just did it for fun lol. Thxs for the copper shim idea, I was gonna gravitate towards one of those tiny heatsinks like the ones that are used on the Raspberry Pi, but found it hard to incorporate it in because of the curve plastic.
I didn't even know overheating was a thing on the G3. I've used it pretty heavily, and I've never even felt the slightest bit of warmth. Is this only for certain models? I've got the D850 and you'd think with all the bloatware it'd be likely to heat up even faster. Though it never did on stock, and even now with an international rom it still doesn't. Regardless, that's pretty cool what you did! Never would've thought of it.. Would've been pretty useful on my Nexus 4 though
Frist off sorry for the “enguish”.
I can definitely understand your point, for the majority of “general consumers” who want no frills phone.
But the way I use my “phone” (if you want to describe the device by that small function), tends more towards this device as a true “pocket PC” and because of that I prefer my governor at MAX freq. At that governor I run an multitude of overlays which sum up to using at least ~30%-100% CPU usage FOR WHAT I CONSIDER “CAUSAL USE” (others deff don’t).
In regards to your points on it not even being a portable anymore, I’m trying to work within "reasonable" constraints, and honestly that 40mm fan only adds 10mm of height(that may be too extreme for some but not I). It still fits in my pocket just fine .
The fan currently runs on a slim 1000mah battery and sits underneath the fan (ripped out of battery case).
I can connect the fan to my phone via a 4pin to USB adapter, SO IM CLOSE to FAN PROFILES all I need to do it figure out a way I could vary the voltage output on the G3 (if its possible via the kernel), and then all I need to do is set some custom Tasker strings and BAMB ---> “Fan Profiles”. ---> tbh Still not sure if this can work.
I believe the reason that the G3 has heat issues is not so much in its strict governor (that’s actually supposed to pervert it) but actually its a fundamental fault (or tradeoff) with the G3s thermal design, If you get a chance to see an IFIXIT takedown of the G3, ull see how the (Vol Up/Vol Down + PWD buttons) sort-of choke the 801. I had found some studies comparing temps of various loads among other 801 devices (ill post them once I find them). But I realize the impracticality of the comparison.
And at least for me, most of the AOSP ROMs on my G3 I've flashed I've noticed higher temps ave temps (w/o using it with overlays or anything fancy).
--> Not 100% sure so do call me out im im deff wrong :good:

Yah see the problem is a lot of people don't realize that their phone is overheating because the plastic(along with the back buttons) does not conduct the heat away from the processor fast enough for most to physical feel the immense heat under the hood, therefore causing the CPU to throttle to a slowdown.
If I wasn't confusing enough, heres an example:
HTC One M9 (Metal body (better conductor of heat)) vs LG G3 (plastic)
The HTC One M9 will feel hotter (and thusly more people realize and complain about heat) but the CPU temps will be relatively lower and thus throttle less vs the G3 "feeling" cooler but the CPU temps run much hotter causing throttling.

Well, i use 75 degree one and it's great. If you think the phone is too hot for you, you could always try 70, 65 or even stock-like 60 degree one.
Image in the OP is broken, just thought I'd let you know. Although I don't get throttling problems. I heavily underclock the CPU to 960 mHz. One thing I have to agree to would heat issues. About 20 minutes of light use and I'm getting temperatures of about 60 degrees Celsius.

I would like to see better EPD with reduced ghosting, bigger storage, and most importantly: lower price. The price has been the biggest issue (apart from availability) which has been keeping the developer community so small: if there are no users, why bother creating applications for the device?
But based on the few articles I've read, most of these issues are being worked on for the next iteration: http://www.technobuffalo.com/2015/0...taphone-2c-heres-whats-coming-next-from-yota/
Edit. Oh yes, a notification led. There is no way seeing if you've got messages apart from opening the front screen in the dark. The led should be placed on one of the sides so it would be visible no matter which screen was facing up.
When they lowered the price it showed less people where interested.

Curious. Well, the specs are falling behind pretty fast, and I think the big mobile giants had just released a new devices around that time. (S6 or the Edge, whatever it was called)
The cancellation of North America's launch migth actually move the release date of Yotaphone 3 closer than it was planned before, because now they don't need to get rid of those North America specific Yotaphones and wait for the market to settle and be ready for new iteration. Hopefully they can compete with the other flagship phones feature and valuewise.
If the specs where higher I think the price was good but the price for yotaphone 2 was too high just for an epd. What amazed me was the lack of development.

Agreed. The development of 3rd party apps was greatly hindered because they released the SDK so late in the device's life cycle - and it's still in beta! The documentation is terrible, if not non-exsistent, and there are very few examples and/or tutorials. I practically had to tear the existing applications apart to get an idea how to do basic things. Also, I still haven't been able to get the emulator to work, so you basically NEED to have an actual device to develop anything. So it really isn't that developer friendly at the moment.
When it comes to 1st party apps, I think they have been quite alright. There is still room for improvement, but as of the latest updates I am ok with the current state. Most likely their development team has been working on bringing the support for Lollipop, so that has taken majority of their time.
Love the V2 phone a lot but too much wrong with it. I am an e-ink enthusiast and I think the display on this phone is fine... there is always a tradeoff between 'cleanliness' and speed... see this vid I made for the Nook https://vimeo.com/67164582 - and really if you want an outdoor phone, this is the only one on the market!
My wishlist
1) Actually have the battery life work as promised. My old Samsung Note does as well and it doesn't have an EPD or any fancy energy saving modes. The Y2 seems to last a couple of days on standby in Lollipop, not impressive.
2) Manage the heat properly in the phone, so it doesn't get excessively hot: that's a sign that (1) above isn't working properly - if your processor is working overtime when just reading stuff you have a problem
3) Make the case openable, so you can replace the battery, otherwise you're doomed to binning the phone after a 18 months- 2 years, and values of secondhand phones will(and are) reflecting that.
4 )Get the software written somewhere where things like QA, unit testing,documentation etc are culturally acceptable. Better to do these things well and deliver small but robust functionality. Okay, it won't sell a stack of phones but at least your service/support lines won't be jammed... and you never know, some of the folks on this forum (and me) might write some software for it!
5) Put a reasonable camera on the phone, unless you like all your shots looking like they are done in the Mosow subway...
6) Hardware buttons on the 'front' of the phone to do things like home, back etc. Makes better use of that lovely display(which is good imho)
7) Sell it with a bumper to protect the phone or make it more robust.
8) Allow you to remove the ABBYY spyware service (a dictionary that needs to know my contacts???) without rooting.
I might get another one but they seem prone to bomb out and get unrecoverable.. it is a big gamble...
It would seem that Yota is teaming up with ZTE for YotaPhone 3: http://www.androidauthority.com/yotaphone-3-zte-yota-642364/
Interesting to see what this means in practice. ZTE at least has the volume in production Yota has been severely lacking.
My whishlist:
I know it is probably unlikely but it would be cool if it was running Android Marshmallow (One step further towards impossible would be CyanogenMod)... Sooo, I don't know the restrictions to this but I know that the Pebble Time has a color e-paper display, if it's possible to upscale that to the bigger screen, it would be the best. Otherwise please either include a SD-Card slot or at least more internal storage than the YP2. I'm not that into much camera stuff but it wouldn't hurt either... And if anyhow possible, do include NFC, please... And as a final 'request:' add capacitive buttons, I'd be switching from a OnePlus One and just the choice is really great. With all this please do keep the price moderate.
Thanks.
TL;DR:
-Android Marshmallow (possibly CyanogenMod)
-SD-Card slot
-more internal storage
-NFC
-capacitive buttons
-maybe camera improvements
-always on E-Paper color rear display
-decent price?
On my wishlist, there would of course be many point already mentioned by other posters, but here's the top features I'm currently missing on my Yotaphone 2, and that I'd like to see in the Yotaphone 3:
1) First and foremost, a backlight for the EPD screen. I mean, my 100 Euros e-ink reader (Kobo Aura) features a user-selectable (on/off, and brightness level) backlight on its b&w e-ink display, and even when keeping the backlight always on at the minimum setting, I still get a month worth of battery life on a singe charge. Don't get me wrong, the EPD, is wonderfull in daylight, when there sunshine, etc. But right now, I find myself using my Kobo reader half the time because I can keep on reading in the dark, when my wife's asleep.
2) Already mentionned, but I do happen to own a Pebble Time smartwatch with a color e-ink screen, and I'd definitely love to see this technology in the EPD on the Yotaphone 3.
3) Third party software. As stated above, due to the limitations of the EPD (lack of backlight) I still find myself using my Kobo reader, and the lack of EPD-enabled Kobo-compatible e-reader application makes it a PITA to keep my ebook in sync between the two devices. Sure, I could use the Kobo reader on the Yotaphone, but the application is terrible and doesn't suport the EPD.
4) A dictionary that do work. Heck, I even went as far as spending a couple of bucks on additional dictionaries for Abby on the Yotaphone, but it seems that the more dictionaries I add, the less definitions it finds when I lookup an english word in my ebooks...
5) Hardware button, LED notifications, removable battery are definitely on my list, but only after a memory expansion slot (microSD), as 32Gb is definitely too small to hold a decent amount of audio/video.
6) I vote in favor of the better camera, but I'd particularly would appreciate a bigger framerate allowing slow motion videos like on the iPhone/iPod. My kids and wife can produce some great slow-motion videos on their Apple devices, and I can't. Life's not fair... )

What do you think of Pebble's color screen in practice? My understanding was that it is basically just a low-power LCD screen, so not a "true" e-ink screen. Does it work well in sunlight? Does it suffer from ghosting like Yota's EPD? Does it go blank when the battery runs out or keep the last image?

I'm really happy with the Pebble Time's color display.
Sure enough, the colors/brightness are far, far from an Apple Watch, say, or my previous smartwatch (Moto 360). But in sunlight the screen is wonderfully easy to read. In poor lighting conditions (indoor, night, whatever....) you do need the backlight, though, but initially I had the motion detection enabled to have the screen automatically backlit when moving my arm to read time, but I found out that most of the time it wasn't needed, and was using power, so now I just press a button (back button) when I need the backlight, and regardless of motion detection the battery life is impressive.
No ghosting at all, unlike the EPD on the Yotaphone, and I didn't completely drain the Pebble battery so I can't be 100% sure that the last image stays on the display in that case.

I'm going with same tactic as I did with the Yota 2 - google phone name every day once. Nothing solid on dates yet, all we really know it's it's meant to come this year and ZTE are building it.
Based on LACK of development of apps / widgets for the e-ink display i won't even be looking at any news about it never mind buying one !!! really disappointed with yota should have been released in usa

They tried with the indiegogo approach, it didn't outcome well. They could insert the HSPA. Here on Brazil they got the LTE network right, but they didn't move yet.
It's a small company and I hope it gets bigger. They try to sell advances in cellphone tecnology, since most of the others big names on the market just update hardware and software, with no thinking outside the box like before.
I just think the prices are too high. Got myself a second hand one (yet yotaphone 1), really amazing device. I need lots of reading, so this device is just great to me.
I hope yota3 comes to USA and other countries.
Best wishes!
Good luck finding a Chinese manufacturer that listens to the needs of existing customers. But at least they will produce a phone with a competitive price.
Wish list? I agree with others' lists, to keep up the radical reputation will require a large colour EPD.
