Camera odd issues [global bug from HC to ICS]

Hi all, just nabbed a 7.7 today moving away from the p1000. I started playing around with the camera and I immediately noticed some oddities especially when switching to video mode set at 720p quality.
Below are screenshots taken with my SGS 2, where I placed the tablet stationary at a certain distance from my printer and tested different resolution settings on the camera, while maintaining the tablet in same position at all times.
First a test with the picture mode, the distances between 480p and the highest quality isn't very noticeable but it's there,
480p
Highest quality with widescreen
This, I have no problems whatsoever, taking pictures still feels the same as the p1000 and that's good because I'm used to that.
Next is where I am really confused. When switching to video mode, I noticed the entire printer seems to be zoomed in closer and the graininess has increased drastically (I suspect the increased in graininess comes from zooming too close to it). I have checked everywhere in the menu to look for zoom settings but alas, after googling around the tablet's default camera app doesn't support zoom at all. Which brings me to an even bigger problem, as it just feels out of place when everything is zoomed in whenever I wanted to take a video recording. After turning down the quality to 480p, it felt so much better with the distancing between the object and the camera. Pics below will show the comparison between both settings,
480p video
720p video
Is everyone else having this same oddity with their camera as well? I hope its not a 'normal' thing cause I'd be hating it immensely (just using 480p mode in the meantime) :|

any kind sgt owners willing to test this out for me and give a feedback?
at least I could pinpoint if its a hardware or software problem, if its different between other tablets.

I am having the same problem. I was wanting to use my 7.7 as a uStream live streaming device for some of our company events, and because of this problem, I am using my phone instead, which sucks because phone calls can interupt!
Anyone else notice vid camera zoomed all of the way in, with no other way to zoom out. Is there a fix?

I have never used 720p video recording before, but after reading this thread I just tried it. Same problem as reported. On 480p everything works fine, but on 720p vid is zoomed in alot. Also quality is way worse than on 480p.
I guess without this thread I would have never noticed that, but this is indeed a huge bug that should not happen on final software for an expensive device like this.
It is advertised with hd video recording after all...

thanks guys for the feedback!
I was almost tempted to try another firmware but with different SGT 7.7's out there affected by this bug, it needs to be reported.
I am pretty sure it is a software problem which is causing the camera to zoom in on HD mode (digital zooming is possible with third party software as I have tried it)
Also, because it is always digitally zoomed in, the quality/graininess will be a lot worse, this is what every tab 7.7 owner will be looking at.
Could anyone guide me to report this directly to Samsung? I'm hoping its fixed before official ICS!

bump, anyone else having the same issues with their camera just give a feedback here.

+1
Also the text is cut off in settings when in landscape.. geez

I have the same issue. Tried using a video recorder app off the market and it would digital zoom 720p and 480p so that wasn't any help.

yeap great feedback
please guys, I am sure this is a worldwide problem for every sgt 7.7 out there,
the default factory setting on the camera is broken
need some experts on this issue and if there's a possible fix

Anyone running XXLC3 rom from mars? Since im still on XXLA4, but i have deodexed XXLC3 rom, so later these evening i'll test the latest camera to see how far this bug goes..

anyone with the new official ICS rom be able to test the camera out to see if they resolved this problem in a stealth fix?
my tab's with mum so I can't try it
I will forever be in your debt

Just installed open Austria ICS and the bug is still there

wow that sucks ! I dont have the sgt 7.7 with me but this is too serious to be overlooked
i guess based on the amount of responses in this thread most of the tab owners never really cared about 720p video recording
this is my FINAL samsung android product... I feel that they have dropped the ball this time, their pinnacle being SGS 2 and I will always remember the younger days when samsung was focused on something good,
now they are just releasing products like different branded cereal without even tasting them first.

someone explained this one to me before since I hate the 'zoom' effect of the screen as well, but as per his explanation, this could be due to the camera pixel, we have a 3.2 on board camera, using it in 3.2mpxl snapper makes use of the whole image sensor pixel array. using the 720P video on the other hand will use only a portion of that array and the software automatically fill the screen. I don't have an explanation regarding the full screen, un-zoomed 480P though,
I dont find this as a problem but if we can just have this adjusted (zoom in and out) it would be much better

Sammy juat stopped caring about their tabs. Gs3 is making sales targets. Thats good enough for them. Too bad! 7 inch market is super competative. If they dont act fast they will lose just like blackbery and their underdeveloped playbok

I am so angry I'm considering ditching Samsung. ICS finally arrived in the UK via Kies a couple of days ago. I didn't have this issue with Honeycomb but now with ICS my P6800 video camera, when in HD mode displays a zoomed image. The only reason I;m not ditching it right now is because of the SuperAMOLED screen - the same reason I paid silly money for it when I could have gotten a Nexus.

I have done some recherching and found out this is not a bug! Many devices have this. I'll try to explain what happens:
If you record videos in HD, your device has to downscale the video to show it to you on display while at the same time saving it in HD resolution and keeping the promised frame rate. This needs too much processing power, framerate would just drop. So they use a little trick: If you don't downscale the preview but only show a small part of what the sensor gets you save alot of processing power. But on the other hand it gives you the noticed "zoomed-in" look, also the image quality is less because it does not use the whole sensor (like it would on a still).
The saved video should look normal (not zoomed-in).
Hope my english is not too bad so you can understand what I mean

Camera ics + doesnt zoom in when recording ^^

Standard poor copy-paste response from Samsung, which appear not to acknowledge that the device isn't a telephone:
Thank you for contacting Samsung and I have pleasure in providing the following assistance.
I’m sorry you are having issues with your device after upgrading the firmware. I can understand your frustration about this.
Old systems settings can be left on the phone after an update occurs, which is why we usually recommend a full factory reset after updating. If this isn’t done your device may begin to give false readings from system resources, or experience technical problems, which may explain the issue you are having.
We would advise on doing the following, which is designed to reset the settings on your device. Please back up your device using Samsung KIES before you do this.
1) Remove the battery for at least 40 minutes, put the battery back in and allow it to fully discharge. Afterwards, perform a full battery charge with the device turned off. Do not interrupt the charging process.
2) After the battery is fully charged, we would like you to perform a full factory reset, which can be done via Settings > Backup > Reset.
This process will reset your device, remove old system files that are no longer needed and enable your device to operate normally again.
Please let us know if your device continues to experience problems after the reset so we can investigate further.
If you require any further assistance, please contact Samsung again and we will be more than happy to help.
Kind regards

I must respectfully disagree. If that were the case then the behaviour should have been the same prior to the ICS update. Also, when copying the video off the device and playing it back on a FullHD capable device the quality is still poor.

[Q] Downscale screen resolution for more battery conserving

1080p contend is supported more often from apps because of the amount of supported devices, I wondered if downscaling the tablet's screen resolution to 1080p is supported by any rom and if it would save a few hours of extra usage to the tablet?

I am no expert but I know that when you give the command to change the resolution it doesn't actually change it, it's more of a virtual/spoofing, to make the system think it's changed. So all the pixels will still be there. But when watching videos in 1080p the "upscaling" won't take much of your battery, if any at all. You won't notice it.

A digital screen only has 1 resolution. To use any alternate resolution it must be scaled to the screens native resolution so if you were to somehow force a resolution other then the native it would have to re-scale it to the native in order to display it which would require additional processing...

You could get better performance, in 3D applications for example but not better battery life.

I am asking for the SoC power consumption,logic says less effort saves more energy,current pixels to handle are about 4 million instead of the half that 1080p are
Though there might be needed optimizations as a modded kernel with different clock speeds

"Logic" that's ill-informed can be just as fallacious as a random guess. Your particular brand is working off of some very silly assumptions, and your second sentence really just highlights that. A modded kernel with different clock speeds? Please.
When you downscale an image, you have less pixels to handle only in the sense that the image becomes smaller. The actual display still requires that all of the physical pixels be addressed before it can display anything. The only reason that you see graphical performance improve in say, a computer video game when you're playing on a lower resolution is when the bottleneck is the graphics card rendering an image. If your computer is struggling with the output, then you have a different set of problems.
On a tablet, a game that's not built to the screen resolution (let's say it's designed for a 720p panel for the sake of argument) will keep load fairly light on the GPU for rendering, but the same amount of work as normal to display (although this is a simplification, it'll work for these purposes). That's because whether the content is 720p or 1080p doesn't matter-- the GPU still needs to figure out how to stretch it to the dimensions of the physical screen.
Bottom line, you're not going to save "a few hours" of usage. All the work you'd need to do normally will still be there, plus the chicanery of trying to transform all video output to 1080p again only for the physical screen to demand its normal resolution.

How do you explain the 3rd ipad (that your sighn shows you have) overheat from the SoC?The amount of retina display pixels caused it and overheat means power loss as far as I know.Anyway your ironic first setence made me loose any interest for rest of your post.

This! I know I was playing Dead trigger and you can enable the advanced graphics for tegra gpus, and it was laggy, but after reducing the resolution (the game doesn't allow this, or didn't the last time I played it) the game was buttery smooth.
And no, video decoding doesn't care what resolution your screen is. It still has to decode the whole video and display all the pixels, weather they are upscaled or not. your battery won't be affected by that. Apps on the other hand, like games, are another story.

Not sure what's worse, clueless people on a site called XDA-Developers or clueless people who refuse to listen to advice.
Whether the iPad has some kind of overheating issue is a completely different matter and can be caused by a number of things. The fact is that changing your screen's render resolution has almost no impact on your battery life. The GPU still has to upscale whatever is rendered to the Nexus 10's native resolution. The biggest drain on the battery is the display itself; it takes a lot of energy to light up a display with such a high pixel density and still be bright enough to see.

Irony is the worst of all,at least some people know what a question is as this thread is

When you ask a question you need to be able to accept an answer that isn't on your liking. You've had 5 people telling you in different ways that it won't help, if you don't want to believe us, then here you go this doesn't work on 4.3, just 4.2 and maybe earlier. You can change it and use it for a week and see for yourself. Just make sure you don't let autosuggestion cloud your judgement.

It's not the answer but some persons that give them that's not my liking

Ahaha, says the new member who has demonstrated 1) that they don't know what irony is, and 2) that they have no idea how to ask for help. Hint: it's not "please validate my preconceptions." The only irony here is your reactions to the thread that you spawned.
My iPad has never overheated, or even come close, really. It's the same crowd of people who will complain any device "overheats" when they're doing something that is going to create thermal load. Newsflash: that will be just about any game or long-term video ever. The 1080p Nexus 7 gets warm under use as well-- oh wait, 1080p is some magical resolution that will fix all your woes, right?
Protip: overheating doesn't mean power loss unless your circuitry gets pushed outside of standard operating conditions and loses conductivity due to thermal deformation. On a desktop PC, it might mean power loss from running the fans up, but as mobile SoCs use passive dissipation, this is a non-starter. Heat buildup is a byproduct of using a processor to do things.

[Q] Downscale Resolution to 1080p to increase performance?

For me QHD displays are too much for a 5.7 inch phone. The exynos version looks pretty powerful, but I guess I`d rather have better performance than insane ppi.
Watching some on/off screen GPU benchmark reviews for the LG G3, Oppo Find 7 and S5 "Premium", the off screen (1080p) tests had an average of 51% higher scores than on screen (QHD) scores. I mean, WOW! That`s a lot! I can post the results here if you want to skip the trouble looking for it.
One guy on youtube changed his LG G3 resolution from QHD to Full HD using NOMone Resolution Changer and used Xposed to change DPI and font scale of native apps to make them work.
What do you think about this? This could possibly increase overall performance+battery life and definitely increase gaming performance.
The videos about resolution downscale on the G3:

Sounds like you need to stay with your note 3

... and reduce resolution to 720p

and, no one cares about benchmarks..

and... lol reading above comments make me laugh
why you bought note 4 if you want to reduce it's resolution, there will be 1080p device later if you want SD805

Daaaaaamn, this a deal breaker... If I cannot reduce the resolution of the Note 4 to 4:3 CRT TV 480i letterbox... I will not buy it, what a piece of crap! I was hoping to get at least 6 months of battery life on each charge with CRT resolution... I reduced to 320i my note 3 and it lasts almost a year on a single charge. The only problem is that I am having issues watching YouTube in HD for some unknown reason.

funny stuff!
we ***** and moan that we want QHD/4K/ultra definition on our "5 inch video screens", then once we get it, we complain that it uses too much battery life, so we have to "downrez" it..
you just cant make some people happy...

I'm more curious of how the screen will look like if in 1080p, especially the pentile effect. We know that we still see the pentile effect somewhat on Note 3, not sure on Note 4's 1440p screen.
Don't really care about performance.

I can't see any difference, but I can't see any pentile on 1080p phones too so...

if you reduce resolution to 256 x 144 battery life will be improved by a factor of 10!
much better than 1080p! OMG!

Is there any sound reason for bashing the OP ?
Just because he thinks a little bit different than you, maybe a step ahead of you ?
His idea is no nonsense.
If it IS possible to boost perfomance by lowering the resolution to e. g. Full HD, that would be quite beneficial.
Practical example: Let's talk about a game, "World of Tanks - Blitz".
Great game on the PC, not so great game on Android. Reason: Graphics are not the best. At present, there's a kind of universal version out, all reduced graphics to make sure the game works with most Android devices, even the weaker ones. Game publisher said they're working on a version you can adapt to the performance of your system. Hope they won't lie.
2560 x 1440 pixels is quite a number.
Rendering that many pixels WILL take a lot of processing power, WILL be quite a burden on the CPU and the battery.
So the results are likely to be: Great graphics but bad performance - or bad graphics because the game recognizes the overall performance as being too low for high details AND fluid gameplay.
Plus: You can watch your battery going down in no time, as rendering that mass of pixels will take a lot of power.
Let's say we've got a resolution of 853 x 480. SOUNDS like subzero quality, but don't forget the tiny screen (compared with a large PC monitor).
If it's possible to display 853 x 480 using the highest details setting, the result will look classes better than 2560 x 1440 with low details. You won't be able to spot single pixels, just a wealth of fine graphics.
So a reduced resolution and highest details will look MUCH better than highest resolution and low details. That's benefit one.
Second, gameplay will be vastly improved by a higher framerate and more CPU power for handling all the netcode and stuff.
Third, our battery will last far longer because of the lower battery drain.
Result would be a great looking, blazing fast game which won't suck your battery dry in no time,
And that's a reason to laugh at the OP, for bashing him ?
I do NOT know if reducing the resolution AND saving ressources is possible.
But IF it's possible, it would be a great step forward.
You will NOT able to see the difference between full resolution and reduced resolution on the tiny Note 4's display.
Only differences will be graphics and details quality - and higher speed, better framerates, more fluid gameplay.
And there will be always some room for compromises like slightly higher resolution and the like.
Now bash on if you still feel like.

Just a bunch of trolls. There are many people dowscaling resolution to play. I personally leave at 1080p all the time. Just restart and everything rescales to the right dpi.

I don't know of a way to reduce it to 1080p, but wouldn't it make more sense to buy an s5? Battery life was superb on my s5, still wouldn't swap it for my note 4 though, optimise your note 4, it holds its own in terms of battery life and performance.

All depends on why you got a note4, I love the s-pen, I like the added fingerprint reader and heart rate monitor, and like the better camera with OIS. I already can't see the pixels on my Note3 though, so why would I care if I downgraded my Note4 to "only" that same resolution? Having longer battery life and higher performance for all the bits that matter to you sounds like a much better plan than having more pixels than you can possibly see.

You didn't get the idea at all. It's about making games run faster and with far better details. Same as with PC games.
Read my post!
Edit: It was me not reading the post correctly. Sorry !

I'd be interested in this also. I would love the ability to lower the resolution for a few apps I use on my note 4

I like this idea for performance in games and battery saving but you definitely can see the pixels on the Note3 and indeed any 1080p mobile right now. The extra resolution on the Note 4 really pays off for normal useage but games should be able to default to 1080p at the very least.
Phones should have a resolution change option like pc's these days anyway.

Sorry, I think you misunderstood. I was agreeing with you. My point was that I don't really "lose" anything if I downgrade the resolution as on a screen this size I can't see individual pixels even at 1080 I was also countering those who said the OP should have stuck with a note 3 by saying that the note 4 has many other improvements as well, and that the resolution, though better on paper doesn't really matter.

NOMone resolution changer in the app store lets you bring it down to 1080P.

Xperia Z5 Premium - Native resolution

Is it only me who thinks that all the videos online show the Z5 premium 4K screen at 1080p resolution ? For such a high pixel density the icons and menu should be much smaller and app list in the menu should be more than 4x5 .
I found a video showing the Z5 Premium running at a different resolution but much slower. I must admit I don't understand spanish but anyone can watch the end where things get really laggy ?

Old software running at 300 dpi. Will not be present in the finalized product

Have to admit that when I hear 4K I expect the resolution to be similar to the one in the video. It makes a huge difference and looks much better.

I had one in the past, the Ultra T2 and although I liked everything about it that time, but sold it after 1 week becuse the low call voice in the loud speakers, althoigh the music was fine . I found out on the net, that may eb all Sony experia has this issue, may be thier standard.
Can you tell me if all the xperia you used has the same low call voice. I am thinking of buying C4 or may be the z5 , but I am afraid to have the same issue.

Premium will not use 4k all the time, only when needed.

You get a larger battery and screen though

It's exactly like macbook pro retinas... you still have the desktop space of the standard resolution, yet much crispier

http://www.androidauthority.com/sony-explains-xperia-z5-premium-4k-642067/
“Xperia Z5 Premium features a 4K display with a resolution of 3840×2160 pixels based on SID Standard and enables all video and image content to be enjoyed in 4K resolution. All other content is displayed at 1080P or lower resolution in order to optimise the performance and battery stamina for this device, ensuring you can enjoy the 4K resolution when you need it most.“

Almost no point of the Z5 Premium in that case, as my old laptop certainly isn't going to render it, nor is my 2010 spec plasma

Once you root it and have xposed installed I'm sure you can set a per app DPI. I can't use a phone if it doesn't have root (won't connect to headunit) and exposed makes everything so much better.

Even if that's the case, you are never going to browse and read at more than 480p. I've seen almost none apps for "simple" things going higher than 480p... Neither Chrome for browsing, nor Play Books for reading...for example!

I Like it
it s smart management for speed & power
I don need 4K rendering when watching HD clips So It s better that phone switch to FHD/HD rendering

Lol u want to browse and read in 4K, but anything above 1080p is nearly undetectable for humans eye
4K will become standardised very soon, as VR goggles are getting more and more popular.
Now, on 1080p, when using VR goggles, the screen does get separated into two images. Thus screen resolution you see thru the glasses be like 400x800 or so..
Imagine, when using 4K... VR goggles will still display 2K.. Which is more pixels than our 1080p res.
Take a magnifier and look at a 1080p screen, count the pixels and multiply that by 2. That's the resolution you'll see thru VR goggles when using a 4k display, and that's exactly what it's designed and meant for.
Sooner or later, Sony will come up with their very own VR goggles like Samsung with VR gear.

Lol u want to browse and read in 4K, but anything above 1080p is nearly undetectable for humans eye
4K will become standardised very soon, as VR goggles are getting more and more popular.
Now, on 1080p, when using VR goggles, the screen does get separated into two images. Thus screen resolution you see thru the glasses be like 400x800 or so..
Imagine, when using 4K... VR goggles will still display 2K.. Which is more pixels than our 1080p res.
Take a magnifier and look at a 1080p screen, count the pixels and multiply that by 2. That's the resolution you'll see thru VR goggles when using a 4k display, and that's exactly what it's designed and meant for.

I dont really understand what's with the "undetectable thing " people keep repeating.
If you browse at 4K, text is much smaller and the content displayed is much more than 1080p . I don't have to scroll 2 pages to see everything where I can see it in only one @4K.
When you buy bigger PC screen you get more space on your desktop ( icons / files etc.. ) because resolution gets higher not because the screen gets bigger.
Whether I can see the pixel or not is my least concern.

That's not about resolution.
Resolution is about pixels.
How things appear on the screen is about layout / DPI.
U can easily spoof ur DPI in build.prop or with an xposed module, even per-app.
Just Google a bit and you'll find out

Higher DPI means higher resolution....
In the first video I posted the dpi was increased as u can see in the end of the video the device becomes very laggy during transition.
bottom line, xperia can't handle 4K resolution.

Cool! So if I just put higher DPI, and everything looks smaller on my Z, that means I suddenly have 4K lol

Does the screen look noticibly sharper after this?
Just wondering if worth the effort/trade off in battery life

I must say that I'm a bit skeptical about this. The screen has a specific number of pixels, in the XA1 case 720 x 1280, and it is not possible to increase with setting a value in Android. Lowering the value is possible since then the software can count several pixels as one (but usually it does not look that good).
In the GSMarena review they use a microscope to look at the pixels and sure they don't count them but I think after looking at so many screens they would have notice if the pixels was so small that the screen was a 1080 x 1920 screen instead.

If you saw my old phone, you too would be happy with the current resolution.
Why pump it up. Uses your battery quicker

Very Eager to tryit out but worried about battery life. Is it worth??

Strong post
thanks for your help , I have been bothered by the xa1 's low ppi for a long time:laugh::laugh::laugh::laugh:

Does this only change the dpi? As stated above you can't add pixels to a screen that's 720p

Yes you r right. but the point is you can view youtube with FullHD setting. and you will get more space, also UI like tablet for some app if you want

I use these settings :
adb shell wm size 480x850
adb shell wm density 240
in settings, display, use the smallest size of font.
you can use too but it's blur :
adb shell wm size 360x640
adb shell wm density 180

I tried this out and my batterylive isnt affected. But I'm not able to take a screenshot anymore

1. Probably not the best idea to publish a video with your pirated movies and MILF porn clearly visible
2. How could this be possibly be... possible? Unless Sony has built in a 1080 display and lowered the resolution via software (why would they?!), I call complete bull****.
What you're changing is what the phone tells YT it is capable of. So you're using more data and also more battery for no visual improvement whatsoever. It just doesn't have more pixels.

And you are not able to take Screenshots anymore

In case of Youtube it helps, because videos are encoded with very low quality to save space and bandwidth.
It always help to use higher resolution of video than screen has resolution anyway. I do this on ma PC for couple of years now.
On phone screen is so small it makes little but still noticeable difference, but i don't care about it, i want battery life especially when I watch YT while travelling.
EDIT:
I've checked the screen with good old cardboard.
It is 720p and android probably is downsampling 1080p to it if You change the resolution.
So in conclusion other than 1080p in Youtube You only waste Your battery life.
If You want 1080p in Youtube, get modded app.
Anyway it is interesting gimmick, but with no real purpose.
