Moto G7 worse the G6 phones? - Moto G7 Questions & Answers

I have some concerns about the new Motorola G7 phones particularly:
Screen - The screen tends to have a blue/cool tinge, the overall display calibration is "off".
Camera - Colours can be washed-out, zoom has many artifacts & noise and poor dynamic range at night. Stabilization needs a lot of work (for both front & back) and overall sharpness/detail/colour could be better.
Does this mean the actual lens is of inferior make & quality?
Will a GCam port be enough to compensate for the otherwise poor camera image quality?
Need help. Thank you.

Unlike G6 and Z3 Play, you cannot change the color temperature.
However, you can install CF Lumen if yours rooted.
I did it on both G6 (compensate green) and G7 to keep the color temperature consistent.

For the screen, I usually use night light. Corrects it easily
I know our maintainer is working on a gcam port last I knew. If you have twrp you can always flash gapps with gcam
But to answer the thread title: no its not worse with more RAM, more storage, better SoC, etc than the g6

I haven't noticed where the screen seems to be blue, mine looks fine to me and other colors seem just fine.
As far as zoom goes this device does not have optical zoom, so of course it's going to be bad. May as well take picture normal then crop, it achieves the same thing. I think stabilization is amazing, definitely a lot better than the G6.
I use the Google Camera port and it definitely takes good pictures but I haven't noticed and differences between them. Night sight is amazing too.

I have a replacement screen and the video looks fabulous over my g4. That died. Get a case or you're going to be looking on eBay for a picture of the exact same ribbon cable printing for about 29 bucks. If the photo doesn't show same printing on the black, don't get it! Real on left, not gorilla glass 3 on the right. I used silicone on the very edges instead of getting that 3M stuff because this model of phone uses the REALLY thin stuff. Did my pic upload?

Absolutely NOT! I feel as though the G7 is USA's G7 Plus with those specs. Lenovo really screwed up not bringing the G6+ to the USA last year. My OG Pixel was trashed (throwing it at a concrete wall) and my closest option to purchase an Unlocked Device was at Walmart. All the devices they had on display were last years models and the very non-knowledgeable sales Rep didnt know what was in stock, so i said forget the display models and lets head over to the storage box and see what there is to choose from. When he opened the box, a bright light shined over and they're were about 8 G7s (non of which was on display). "Oh we cant sell them yet" WTF??? Go I got stuck taking a G6, but I was NOT a happy customer. Contacted Walmart Customer Support and 2 days later i returned the G6 for my awesome Moto G7.

I do repairs so I see complaints about color accuracy on devices all the time, but you can take devices straight out of the box and there will be variations because there is an acceptable tolerance otherwise they'd be throwing out so many screens. The ones that tend to get the most complaints are the ones at the edge of the tolerance.
3m tape is awful for screen replacement, we use the black Tessa tape, it's super sticky and doesn't like to let go.

Camera Fix for the HD

I searched for a camera fix for the HD camera with no success. Does anyone know if there's going to be a fix in the near future? I'm sure that ya'll have the same problem that I do. Camera takes pictures that look old & rustic. Brownish tint to them & not very sharp for a 5 MP camera. I have adjusted all the settings for light & junk but nothing fixes it. As far as I'm concerned, it should take pictures IDENTICAL to a normal 5 MP digital camera. I can promise you that it's not doing that. Any help would be great, thanks in advance.

Why should it take pictures identical to a 5MP camera. The lens on the front is going to be vastly different, the sensor maybe 5MP, but what is the spacing on the sensor pixels? The closer together, the noisier the image. Colour balance will be down to the sensor too.
Regards
I'm not talking about the front camera. The normal camera on the back. I understand about the pixel thing, but it still shouldn't be so brownish, right? The pictures look like an old Polaroid picture. You know, the one's that spit the picture out as soon as you took it. Old, brown & nasty looking.
My pictures come out fine...
Hmmmmmmm...................... I'll just keep playing with it.

I'm not being flippant, but is it possible you might have a dirty lens?
Lol, that was the first thing I tried. Cleaned both sides of the back cover & cleaned the lens on the camera. Good idea, though.
The "5mp" doesn't really mean much, as stated earlier, if the sensor and lens are poor quality. As far as I know, HTC haven't released a phone with a reasonable quality camera, yet.
I bounce between different smart-phones (just coming back to WM now, after a year with S60). I can say that many of the S60 devices (in particular the Nokia N95, but also the N82 with Xenon flash) have very good cameras, being similar to low-end digital cameras in daylight. They lack optical zoom and tend to over-compress images, but have good quality lenses.
imho hd camera is excelent
pictures look old & rustic only if you make them inside house without using the artificial light setting, and this is also a general rule, not specific to HD.
Never seen a good phone camera yet, including the latest 8mpixel ones. They're all terrible.
Never
This camera will NEVER take pictures anywhere near what real cameras do. The photo sites are so tiny, they are smaller then the length of waive of light. Therefore noise, lack of dynamic width, etc. No patch will ever fix that. Sorry
open back cover , clean the lens , you will see a huge difference in quality

Not that I'm doubting you or anything but you do realize that the back cover only has a hole through to the lens?
You might try setting the brightness higher:
If you touch the small rectangle near the bottom right side of the screen (when holding landscape)
Then select the gear symbol, then select brightness from the menu and hit the "+" until it looks better that will remove most of the darkness.
The camera is a plain disappointment. In the time the camera autofocusses, I could have bought a Sony Ericsson C905's, create a good looking photo (with xenon flash) and upload it to imageshack.
If 'your object' makes the slightest move, your photo will be blurry . This is also the case when you attempt to make a photo of someone that isn't aware he or she has to be waiting for the autofocus lag. Head moves >>> blurry pic.
iPhone camera shots are way better quality, don't ask me why. Overall my Touch HD scores 8/10, where atleast 1 full point is taken up by the camera
and it's better don't speak about the very laggy video recording

Too many megapixels on a tiny sensor = major noise problem = blurring from denoise.
Even 2mpixels is too much for sensors this size, but people buy on marketing numbers of megapixels, not quality. You can just imagine the whining that would occur if the Touch HD came out with 1.3mpxiels, even though it would produce better pictures.

hehe, thats true.
mpixels dont count as much as the general public belives. the more mpix. the higher rezolution you can print the picture in. but for ordinary photos, 1.3 mpix would be enough, as long as the optics is good.
Personally, I rarely use a phone camera.
I use either my Olympus 720SW or Canon EOS.
​
the camera sucks **** compared to the n95 and the video recording is horrid. i know it's not meant to be as good as a dedicated camera but this is pretty bad given the price of the device.
i concur with mach03, move the camera a slight bit and eveyrthing gets blurred. one way i've semi gotten aorund this is to unlock the burst functiona nd take a sequence of pics and hope one or two coems out alright, not the most economic way to do it though...
i would ahve thought that maybe there's a way to tweak the camera to stop the blurring or even affect how much light is picked up by the lens which should also help with clarity

Just got my Focus

So my HD2 touch screen decided to die on me and my work has been trying to get me to jump on their AT&T plan. I was hoping to hold out until the HD7S showed up on AT&T (which I now think it never will) but since it's not available I went with the focus.
After using the phone for a few days I really like it. The sound quality is better than my HD2 (running WP7), call quality is excellent (but the focus gets HOT compared to the HD2) and I really like the camera quality. Pictures look really good.
So the bad - and this part confuses me. People were raving about the screen quality of the phone, that the super AMOLED screen was incredible. I think it's terrible! The pixels are the size of waffles compared to the HD2 (yes I am exaggerating). Yes I can see the screen in sunlight better but that's it.
I wanted to get the opinion of some focus users. Do you think the picture/screen quality is good on the phone?
It's certainly not an outright deal breaker but I might jump on the HD7S if it comes out within the next month.
So to recap: Love WP7, love the focus sans the screen and hate AT&T
Mate, I own a Focus now too.
I owned WP7 phones in this order: LG Optimus 7, Omnia 7, Samsung Focus.
One of my friends has a HD7 so I can say I've seen the first phones closely. I think one of my first posts here were about the quality comparison between these phones.
To summarize it, put side by side, the phones are:
Screen size:
HD7>Omnia7=Focus>Optimus7
Screen quality (I know it's subjective but I'll detail later)
Omnia7=Focus>Optimus7>HD7
Battery
Optimus7=Omnia7=Focus>HD7
Phone build quality:
Omnia7>Optimus7>Focus>HD7
Sound quality (overall)
all seemed about the same
That's my impression.
Now about the screen. Put side by side any LCD (Optimus7/HD7) screen with the same thing on alongside Omnia7/Focus and you can't miss the difference. Also, if you're complaining about the size, I can do that too. I can't use only one hand to tap all across the HD7 's screen, I need to use my other hand as well, while on the other phones I can do it with one hand.
To summarize: The contrast, brightness, colors, legibility is simply better on Amoled than on LCD.

The contrast is better and so are the colors but I have to say that's it. At least when comparing the HD2 and the Focus. I am watching netflix, looking at pictures and reading web pages side by side and the HD2 picture is more crisp and text looks better.

That's because Focus screen, which is Super AMOLED, currently uses Pen Tile subpixel arrangement that have half the number of sub pixels as normal LCD screens. It could be problematic to some but not noticeable to others (like me). Next generation Super AMOLED Plus will double sub pixel count and a few other quality improvement.
If you can overcome this subpixel deficient issue, the screen visual quality, especially the contrast, is next to none. Some might argue that the color is too satuated.
I personally will take contrast over pixel counts. Can't stand the forggy screen. That's why I only buy Plasma TVs vs LCD TVs. Die hards would willing to spend $3000+ for a used (no longer in production) Pioneer 50" Kuro plasma TV over any fansy new TVs today because they know how to cheerish the superior black level (and hence the contrast) or a Kuro TV that none of today's HDTV can match.
Also, be careful of screen burn in. Don't let bright text display on the screen too long. OLED screens are very suspectable to burn in because the pixels have a very limited life span.
I hear you on the contrast - I own a 50" Panasonic plasma that I will be hard pressed to part with. I like how the picture looks compared to most LCDs.
I just looked on AT&T's website and they are showing the HD7s on the list of wp7 phones with a coming soon tag. That just happened today so maybe they really are getting it soon. It's got a really nice super LCD on it and once it's in the store I will compare the focus and it closely and get the one I like best.
One point that may keep me on the focus though is the camera is a lot better. I took some low light pictures on the focus and they came out great. On the HD7 - not so great. Maybe the HD7S will be better but we will see.

V20 Bug - Purple Shadow when Taking Night Pics with Wide Lens

Hi Everyone,
Have a look at attached example image to see what I mean.
Please try to take a manual shot with your wide lens in a very dark environment with very high ISO (3200 in example) and exposure time of 5secs plus (20 secs in example).
Everyone who has tried that so far has the same issue, a big purple shadow on the top. It's most likely the laser and it won't happen with the normal lense.
Do you have the same result? Any suggestions what we can do about it?
Whoa! I haven't seen that in a long time. I think maybe around the time of the Nikon D80. I can't currently try this out personally but by the sounds of it what has happened is called Amp Glow. It's when you kind of start getting out of the bounds of what is really acceptable shooting conditions for a given sensor. In this case, if you really are shooting in conditions that call for high ISO AND still need a shutter speed of 20 seconds and the image still comes out that dark, then you're way beyond realistic expectations for shooting with a cellphone. In the older DSLRs, people would see it when doing star trail photos that were 10 minutes or longer. Frame stacking software became the solution to this problem by taking a lot of shorter photos and stacking them up and pulling through the new dots of light. (And this is still used by a lot of photographers as it also gets rid of other forms of noise.)
So what is happening? ISO is pretty much the gain. It's the amplification being applied to the signal coming off of the sensor. Ideally with ANY camera, you want to stay as close to the base ISO of a given sensor. That's usually the lowest ISO number. (There are some exceptions where some camera manufacturers have done some trickery to get a lower ISO to show up but that was short lived as it didn't really help things.) Unfortunately, image sensors are not hanging in space. They're packed in with a ton of other stuff. Stuff that gets warm. If that stuff is near an edge of the sensor, that heat bleeds into the sensor and then those warmed pixels get amplified by the higher ISO and next thing you know, Amp Glow. Well, that's the simplified version at least.
A cellphone, any cellphone, is not designed for those kinds of shots. If they were, they would have a tripod mount, a much better flash, and a much larger sensor. (Yeah, the flash on your cellphone is not meant to light up stuff much past 5 feet. Even the ones built into a DSLR aren't meant for much past about 15-20 feet.) The reality is that cellphones are designed for handheld shots with decent light. Even the larger sensor used in some cellphones shouldn't be expected to pull any miracles that top end DSLRs are just barely pulling off cleanly. For that shot, you would want to use a dedicated camera locked down on a tripod using base ISO and long exposure at the very least. Although, personally, I'd probably just take a pass on that shot.
someone on reddit has the exam same issue with the wide angle. and someone said it's in the regular too. weird. my s7 never had this purple hue when I did even 30 second exposure at night.

something obstructing the lens maybe, or just camera went bad
Better hope this isn't the same problem the HTC one m7 had with the purple haze. The culprit was a light sensor on the camera would overhear and give a purple haze on the screen in low light. Place the phone face down and with the camera on and see if the purple comes back.

No, it won't happen with the same ISO/Shutter settings I took the previously attached photo. But maybe that's because it's not dark enough. Did the M7 issue only happen in dark enviornment as well?

Settings aren't the only part of the equation. The other par is the placement of other components within the device. I need to look at the tear downs to see how the various parts are placed next to each other but something is heating up and passing that heat to the sensor. Just off the top of my head there are four parts together; the two camera sensors, the laser focus module, and the flask module. Each one of those on its own will generate heat if used enough.

It's the same issue. I haven't looked at the HTC issue but from your description of it, it's the same. Amp glow is what it is called in digital photography. (OK, silly that I said digital as you don't get amp glow in film.) The glow will show up because there is no other data coming off of the sensor for those pixels and the heat is amplified as "data".
---------- Post added at 05:15 PM ---------- Previous post was at 04:59 PM ----------
Ok, just watched the JerryRigEverything repair tear down. The flash module sits right next to the wide angle and the laser focus next to the regular sensor. There is no mention as to what is sitting next to the sensors on the main board but I see silver boxes on each side with one having some sort of black and yellow warning sticker. Not sure what they are so I can't rope them in as culprits. So for now, I'd say it's a combo of the four units of the camera assembly.
Were you running the flash or one of the cameras a lot while you were playing around? Shooting a lot of long exposure shots in a row?
I'll get to test out some night shots and video tonight at a lighting ceremony but I'm still not expecting to shoot 3200 for 20 seconds type shots. Again, that's pretty extreme.

I know what's wrong with g5plus camera.

The highlighted thing about g5 plus was also the reason for bad camera. The 1.7 aperture and wide angle camera are the cause here. Though it is good for shots within a certain distance like 10-15 feet. But any further the pictures loose sharpness and gets noisy due to which moto decided to use high denoising due to which the photos look soft. My father's redmi 4 clicks better distance pictures than this. It has 2.0 aperture and little less wide angle lens.
Don't forget that G5 Plus have the same camera sensor as HTC U11 or Asus Zenfone 4 (which takes good pictures on stock software).
Worse photo quality is caused by software (Motorola/Lenovo screw it up).
Did you tried any mods/apps? You can find a lot of these, but I suggest you to try Google camera app port.

I use bacon camera on stock Android without root.
I disabled noise reduction and use hdr with manual mode and stable hands to get though grainy but nice pictures. Though the app is not perfect but it works
When I first got the G5+ I thought the camera was too dark... While a lower aperture may help in low light shots it does cause a bit of trouble for highly illuminated scenes.
HDR does compensate but it's nothing like HDR+ from Google.
Plus, terrible sharpen and overdone Noise Reduction excessive Color NR.
I felt quite dissapointed comparing it to my old Titan (G2)
Anyone tried to mod the camera to enable debug mode? You can disable noise reduction from there

Coming from an old school enthusiast of photography background - you're aperture on your lens (in this case f1.7) isn't going to cause noise - that's a function of the sensor. A lot changed when we went from film to digital sensors, but the impact of the f number of the lens did not.
You might be on to something with the with loss of sharpness though. Typically a fixed focal length lens is at it's sharpest at it's only setting... but they very well could have forked this up.
Given that the camera does pretty adequately with other camera software or other hacks - I don't think it's a hardware issue or lens issue. It could be a cut rate sensor...
It could also just be that whomever chose the default settings for this camera did a bad job

What about shadows in bright scenes such as outdoor scenery?
I mean, wouldn't lens aperture like f2.2 preserve more of these details?
That's a function of the film/sensor.
Your f number controls light and the depth of field (area that's in focus) - a smaller f number is more desirable because it allows more light to the film/sensor.
The only thing different here than fine that I can see is the size/diameter of the lens related to the f number. A larger f number, like f 8 or f16 increases the depth of field and sharpness, but at the cost of light hitting the film/sensor. That results in a longer exposure time.
A wide open f stop means more light and shorter exposure times.
One thing we gained with sensors over film is a wider range between highlights and shadows... You could get more shadows and more highlights. Film could get only so much of that before shadows went black and highlights blew out to white. But you still have a limited range. You can't get it all. In order to keep the highlights from going completely white you have to trade off some of the shadow range.
It's early and I'm probably explaining this horribly. Your spectrum between black and white or shadows and highlights is very long. But your camera sensors capability can only encompass a range of that spectrum. If the spectrum were a line of shades of grey from black to white that was, say, 10 units long, the range you could get in one image might be six units long. You've gotta give up somcombo of four units either at the black end of the spectrum or the light side.
If the cameras loaing details in the shadows that's because it's opting to the highlight/light end of the range.
So lens doesn't play a huge role in what chunk of the spectrum the film/sensor can encompass. But does play a role in how quickly the sensor can collect that info. Higher f number = smaller amounts of light on the sensor = longer exposure times.
My guess would be that the sensor or software is biased toward highlights because it results in faster exposures making life easier for snap shots and selfies.

You might be having a bad Xiaomi A1 - Comparison

Hello guys,
Just to post to warn you about the quality difference between the A1s
A bit of background:
I have bought a Xiaomi a1 for my gf, and i was really impressed by the built quality of this budget phone, the screen was very nice especially and the camera quality with GCam or even in Panorama mode was insane. (I can show some pics if you want).
So I decided to get one for myself, for quick travel photography, along with my full frame camera.
I have just received it and I am so disappointed, the screen is bad, it has a yellow tint especially in the top left corner.
The camera is extremly bad, it has a built issue and it's not sharp at all.
Now I will try to get a refund (bought it on Aliexpress).....
So yep, be careful, test your phone when you receive it, you might be unlucky and get a crappy version
My screen glass has defects on the inside (right where the LCD and glass meet), it's positioned at the upper left of my screen, the 2-3 small imperfections are really distracting. It looks like an indent from the inside causing small black spots on the glass. I can't show it because the camera won't pick it up.
Im one of the unlucky too.
My phones screen is separating from the frame on the left and right side.
Battery is so bad like I get 1 hour of full charge
USB C port is loose. This phone never fell out of my hands its falling apart on its own!
Wow, it seems i am not the only one, the quality insurance at Xiaomi seems to be their weak point.
It's sad, because when you stumble on a good one, they are real beasts for the price!
Its the worst phone I've had. Even my Galaxy S4 is better and more durable then this piece of c*ap
Got mine last October when it released and no issues. Built quality and screen are superb. It also takes great pictures with gcam installed.
My Mi A1 hasn't really had any issues, I bought it from my friend's cousin so it's second hand but he really took care of it. Nowadays I'm having a great experience with it, I'm just afraid about EMMC degrading like some users have reported... However, It has 8-9 months already and it's running pretty decently
Dropped mine about 30 cm and a flex cable got loose so I had to open the phone and put it back.. But flawless ever since :silly:

Yep, I have already checked, and they are virtually the same, here is the result:
The screens are the exact same: GFF, Vendor: Tianma, ICtm1911(focal)
The cameras too, but I think it's the same for everyone.
For the rest, the only difference is that mine is a 64 gb and the other one a 32 GB.
