Adjust contrast? - Nexus 7 (2013) Q&A

Hi,
I like my Nexus, but it has one flaw that really bothers me: when playing videos, dark scenes look absolutely horrible. The blacks are grainy and the colors look washed out. It's a step down from the first generation Nexus 7. Is there a kernel or ROM I can install that would let me adjust the contrast?

Are you sure the problem isn't on the video/file instead?
Try using another video player from the playstore?

Voodoo screen fix

I see that Voodoo sound is being implemented left and right... but what about the screen? Our device would benefit more from the screen than the sound, IMO.
If the voodoo sound is as good as it is supposed to be, awesome... as far as screen is that a video settings app??? I would really love a full suite of vid settings, including gamma etc... if I can feasibly watch movies I wanna ISF calibrate the display, one: because im retentive that way, and two: see what this bad boy can do with proper calibration...

Although it looked washed out (but super bright), I'm curious what BThomas did in his Epic ROM that altered the color. His was the first that I saw that had voodoo in there.

GPU failing?

All of the sudden most images have horrible color transition (especially gradient images) and nothing is as sharp anymore. Tried factory reset but didn't fix it.
Anyone else have this happen? I just exchanged mine too and got a screen with no black blobs and minimal lines but now it's worse than my original phone.
What gives? Even HD video looks like crap now
Not rooted stock 2.3.5

After further testing everything appears fine in the gallery when I view an image, but as soon as I set wallpaper or watch video it's messed up looking..
Weird thing is it started after I updated widget locker.

I'm not sure what to tell you on the video, but as far as images go I initially had problems with images that were saved to my sd card. They looked terrible when I tried to set them as my wallpaper. I was able to go back to my laptop for some of the pictures and re-download them which fixed the problem.

Didn't make any difference. Even tried some of the walls that come with the phone, same problem.
Weird thing is when I view a wallpaper in the gallery,I can zoom in full screen size and it's flawless. As soon as I set it as a wallpaper it's slightly blurred with bad color transitions. YouTube videos that were formerly flawless look sub par. Wtf?

The wallpapers have nothing to do with the gpu so idk where you get off with that?You might need to do another exchange my sg2 displays wallpapers just fine. Maybe your youtube isn't on high quality most youtube videos look like crap on low quality. Try doing a factory reset. The only time the gpu should be in effect is when the 3d gallery is moving in its little animations. Are you sure your wallpapers are hpdi and high quality?

Well my question about the GPU was because the videos don't play crisp anymore. And yes that's on high quality, don't act like I'm a moron. All my wallpapers are extremely high quality images...and I do graphic design so please understand I'm telling you like it is. Maybe it's the screen going out I don't know, but I see more vertical and horizontal lines now than previously, images are choppier,lines are not smooth. If you would have read my posts you would see I stated that I did a FDR and it did not solve it.
I really think the widget locker update did something, it was right after that and the dev has acknowledged the issue, he was able to reproduce and is working on a fix.

possible to get better pics with another camera app??

So I'm coming from an S4 which i thought had probably the best camera out there. While the One's camera is pretty good, I occasionally get blurry or not so great pics. I was wondering if another camera app might produce more consistent pics, or if it is what it is.
I don't want to sound like I'm complaining about the camera, it's just I'm trying to see if there are ways to get better pics.

I'm afraid to say that we're limited on the hardware perspective...

Yeah, that's kinda what I've been reading. Don't get me wrong it's not horrible, I just wish it gave more consistently good pics.
Anyone reading this, have you adjusted any settings to get better pics?
I think it's software. For example, I sometimes get pink tint or a little blur with the stock camera app. But I also have vignette camera, and there is no pink tint or blur when I take pics with that camera. The only problem is vignette needs to update their app to work properly with the One, because it's only allowing 3mp pictures, not the full 4. :/

I also believe it to be software as not everyone has the issue.
I think it will be fixed soon with an OTA.
I 3rd party app actually may work better.
great thinking OP

to that end, I took one with the stock camera and another with Vignette. The stock one is bluish/purple. Vignette is not.

Both your problems can be solved by changing the camera settings.
The colour cast can be fixed by changing the white balance, and if you set the ISO higher, your shots should be less blurry (but slightly more grainy).
The "scene" settings can be handy, and if you pick the one to suit the lighting, it should give good results.
You could also practice holding the camera steady.
I really like the stock camera.

That's as may be, but the auto setting should automatically give you the right settings...It is on HTC to fix this, because we don't always have time to change the settings to get the one in a million shot of my 10 year old!
I have noticed that the Night setting gives me a better result...And I love to tweak my settings, but I wish it was easier to get to them. Maybe some "hot" buttons!

Oversaturated colors on landscape mode in videos

Hello everyone, i bought this phone a little while ago and i'm very happy with it...that until i found something ugly. Whenever i want to watch a video on full screen (landscape mode) the color get so over saturated that, for example, a face loses all it's contours and it almost looks like its glowing - on portrait mode the problem is there but in a much much lower scale (almost unnoticeable). I tried changing in the settings the color mode and the screen brightness but didn't help a bit. The weird part is that if a take a screenshot, the colors of the video looks normal...so i don't know what to do. Hope someone can help me with this.
Thanks in advanced!!

Change player. Try VLC or MXplayer.
Good luck!
Hello! I'm having the same problem. Mine does this on YouTube and Google Files as well (though the latter isn't as extreme). Has anyone found a solution yet?

Hi. Today i noticed that the oversaturation problem it's still there, but a bit less noticeable (i hadn't watched any youtube videos for days)
Two things happened, since i posted here:
Did a factory reset (settings->system->advanced->reset options->erase all data (factory reset)
When i turned on the phone after the factory reset i got the update for the october security patch (i'm from Chile)
After the update i immediately noticed that a horrible bluish tone that the screen had was gone and today i noticed the oversaturation problem, as you said on youtube videos, was less noticeable.

Question Whats wrong with A52s auto white balance

I would like to hear some opinions on this. I noticed some time ago that my videos had very inconsistent colors - there would be visible change of the balance when paning around or filming different objects to an extent that seems odd. After trying out and comparing I did realise that the main camera tends to very aggresively change the auto white balance, even if the scene is basically the same and the phone just slightly changes angle. It seems as it tries to desperately match white balance to every frame and its content (forgive my amateur vocabulary here), which to me seems strange and looking at other phones they just hold a much more consistent balance.
I attach 2 videos to show the issue - keep in mind that the issue isnt as visible always, as I tried very specific scenes/angles to show it.
When I use manual white balance it works great, so it kinda feels like a software issue (?)
Does anybody have a similar experience?
Would you mind trying to film a video in a similar scenario, but after disabling the option "scene optimizer" in the camera settings? I don't know if it does anything, but might be worth trying.

Thanks for the tipp, I'll try to compare it, although I dont think that scene optimizer affects videos
Unfortunately turning scene optimizer off doesnt change it (video attached).
It still feels like a software issue, but since nobody has yet confirmed a similar experience I'm starting to think it might be a problem with my unit. (Btw my A52s seems to have the Samsung image sensor not the Sony one)
Edit: or, I am exaggerating and this behaviour is actually not unusual - havent had a Samsung phone for a few years before my A52s

I do not shoot a lot of video, but in the few videos I did shoot I never saw what is visible in your videos (Sony sensor). It is indeed very jarring. Do you only have it with footage of grass or just always?
In the Samsung camera app, you can go the "Professional Video" mode in the "More" section (so where macro etc. is), and then set whitebalance manually to e.g. 5500K and see whether it is more stable then. But like I said I do not shoot a lot of video, so I certainly do not have experience with that professional video mode.
Edit: I now see that you already mention manual whitebalance yourself. So are there disadvantages to just using professional video mode all the time then?

It definitely gets more visible in outside scenes, more so if there is a lot of green in the frame - indoors and with artificial light it definitely is hard to spot. As I mentioned above it feels like it tries to match the balance to the content or objects of/in the frame, instead of keeping a consistent balance. I had a video where I stuck my hand in and out of the frame and it would drastically change the whole color to match the hand it seemed (thinking about it, the background was grass also, so ...).
Pro mode is a solution, it's just that I'm not a fan of setting the balance everytime I take a video or photo - and the balance ofc affects photos in the same way, as 2 photos of basically the same scene might have drastically different WB.
Nevertheless thanks a lot for your input - I also very much enjoyed your detailed instructions for Gcam usage

You would not have to set it every time (probably). In the Samsung camera app I have dragged the Pro Photo (not video) mode to the 'main bar' (from the more menu you can hold and drag items in and out of the main bar for quick access), with a changed fixed ISO (for shooting of fast action scenes), and you set it once and the camera app will remember that setting forever. And I think for all outside scenes around 5600K WB will work fine (it's not like the A52s is a high quality video machine anyway).
I didn't want to bring up gcam because I had no idea whether that would make a difference, but now that you brought it up, does that have the same whitebalance issues for you (in video)?

I meant I would have to set it again for every scene, but you are right, something like 5600 would probably be okay for most outdoor stuff. And with rearranging the icons it wouldnt be such a hassle. I'll try that out for daily use, thanks!
I am using BSG gcam also, because I find the nightmode drastically better but unfortunately the balance issue is the same, so I guess the balance gets set on system level. I also tried gcam awb but it always seems to be a bit off no matter the config - but I prefer the stock app for daylight anyway (apart from the wb)
