Screen washed out after playing video

Anybody else noticed that the screen is washed out/blown out sometimes after a video plays (mainly Netflix, maybe)? It seems to be a combination of increased brightness and decreased color saturation, making colors seem... well... washed out. It goes away after either shutting the screen off and on or switching to another app. I think. I haven't found the pattern yet.
I'm guessing it's Nvidia's Tegra 3 PRISM tech at play, and it's just not shutting off after the video app is closed. I'll expect a software fix at some point, but just want to see if anyone else is experiencing it.

Well son of a b... that is what is causing my washed out colors and gamma. I noticed it seemed to come and go. Unfortunately it never seems to completely clear up for me, even after going to other apps.
I tested this with the Transformers movie. After playing that a few seconds, I left and noticed the home screen looked really saturated, then went to the browser, and it was the same.
For me going to another app doesn't seem to clear it up, but it does clear up partially after a period of time. And maybe it might be my imagination, but it doesn't seem like it really ever goes back to normal until I reboot the tablet.

next to my work ipad.. the colors seem really blown out. =\ also there seems to be a video stutter / jittery issue during the panning effect. Played it side by side with my S3 and the s3 can render it just fine. What gives?

Haven't noticed anything like that after watching videos or movie on nexus 7. display looks great 24/7

No, I see it happen with YouTube and Netflix too. I was just trying to make a futile attempt to understand why this happens to some of us and not others. My guess though if you haven't seen it with other videos, the Transformer movie won't do it either.

I've noticed that it's most obvious on some screen elements, but not all. So, it's entirely possible, I think, for someone to be experiencing the effect and simply not noticing it.

I've noticed this as well quite annoying.

The after movie wash-out appearance was particularly noticeable when looking at small fonts on a white background. Such as this forum.

Yeah same for me! I'm on my 3rd nexus because of dust under the screen, I can't remember my previous 2 doing it. Will it be fixed by an up date doyou think? Or could it be hardware related?

I finished watching the transformers movie this morning. Looked great to me. I can't notice any washed out colours.

I just started getting the "whiteout" too. Not from anything in particular that I can tell, it happened twice coming out of sleep mode.
Anybody have a fix? Is it Hardware or Software related?

>Is it Hardware or Software related?
Take screen cap. If cap image is likewise washed out, it's not hardware. If cap image isn't washed out, then it's more complicated.

I tried it on all the same things you listed. Didn't notice nothing some of you described at all. Screen still looked sharp n crisp. Colors looked fine and not washed out.
Its more than likely the nvidia feature kicking in. Especially if you have brightness set up higher. Probably doing it to save battery life. I keep my brightness at 12% and its more than bright enough for me to see everything well. I heard the autobrightness likes to act up so THST could be am issue also if you have that on also. I never use autobrightness unless I take device outdoors.

Can you give me the quick answer on how to take a screen capture on the N7? Thanks!

Just took several screenshots and swiped between the screen that was normal screenshot and the faded screenshot and they both look the same for me, which is lovely with nice rich colours. If I stick transformers on for 20 sec its washed out when I exit, as soon as I turn the screen on and off its back to normal. I just think its a bug in the screen settings when exiting a move or game. Used to happen on my PC until I updated the driver.

You just hold the volume down button and the bower button, it will take a snapshotof the screen. I've tested it though, see my above post

I'm having the same issue too.
Happens when I watch a video on youtube, netflix or play movies. I use a brightness app to change the brightness levels and it returns to normal. I'm also getting the "screen flickering" issue described here http://forum.xda-developers.com/showthread.php?t=1740385
I really hope these issue with be fixed with an update. I'm new to android. Where's the best place to report these issues direct to Google/Asus?

>between the screen that was normal screenshot and the faded screenshot and they both look the same for me, which is lovely with nice rich colours
So it's probably hardware (display), or a combo of hardware/firmware.
Power-saving feature of Kai's PRISM display pertains to color saturation and brightness. As OP indicated, malfunction may be related to that. But it doesn't matter what the exact cause is.
It may or may not be fixable via firmware update. Suggest getting RMA process started, then sit on it for a few days to see if OTA fix happens. Don't wait beyond the return period. Make sure to ask for advance replacement if RMA.
>I just think its a bug in the screen settings when exiting a move or game.
If the issue was firmware-only, then it would happen to all units, not some. It's either HW, or HW+FW.
Edit: Suggest trying different movie players and different movies to find extent of problem.

So question for the community. If you're having issues with the "whiteout/washout", the ghosting and flickering... would you recommend getting a replacement or waiting for a driver / firmware update?

[Q] Video Playback Issue

Hey guys, need a bit of help...
Been using the Z a few days now, and I'm having 2 issues...
WiFi and Bluetooth won't work together at the same time, one knocks the other off whenever I'm browsing and listening to music on my Bluetooth stereo... In the ratio of about 5:1 for WiFi:Bluetooth like...
That's one issue that's a little annoying.
Another is that video playback over WiFi is broken... If I load up a video on the YouTube app, depending on video length, the video normally freezes around the 40 second mark. If I load a video up in my browser, more of the video will load, but never the full video, could freeze 3 minutes in, 5 seconds in, but never fails to freeze.
I've reverted to stock YouTube app, cleared cache, didn't solve a sausage.
I haven't gotten to the end of a single video since I bought the device.
EDIT: Above issue is most likelyan android wide YouTube issue, if the comments on Play are anything to go by.
And that's on top of the Bluetooth/WiFi clashing that I mentioned above.
Not what I expect from a quad core device with 2GB ram like! Any ideas? Faulty handset? Factory reset? Return the handset? I've never rooted or used custom firmware ;so don't really know how to go about it, open to any suggestions to get the best out of the hardware...
Thanks in advance guys.

WiFi/Bluetooth issue
Seems the YouTube issue is an android wide issue, sorry for bringing it up.
Just leaves the Bluetooth/WiFi clashing issue where they keep knocking each other off while they're both being used.

YouTube app not auto-selecting/defaulting to HD quality

This was never a problem before, but I'm noticing the last couple of weeks, whenever I view a YouTube video on my Z3C, it keeps selecting one of the lower qualities and I have to manually switch to 720p almost half the time. Back then, the highest quality was always chosen by default and my internet connection is fast (enough) so I have no idea why it does this. Is anyone else experiencing this?
I tried downgrading/upgrading the YouTube app and comparing to other phones, but it seems only I'm having this issue. Now it's starting to affect other videos I stream over the internet from different sites/links as well so I'm kind of stumped at the moment.

not sure about the other streaming videos, but do you have limit mobile data setting checked for youtube?

I did check, thanks for the suggestion. I always make sure to take off any limitations as I have unlimited mobile data. And actually, I'm having this problem on Wi-Fi. It's a tiny problem, really, but still annoying nonetheless.

I'm retracting my complaint about other streaming services defaulting to lower quality, turns out it was only happening on one site and that tricked me into thinking it was happening on others as well, but in fact, it was the site's fault, not my phone.
That said, I'm still having the issue with the YouTube app where it automatically selects the lower quality when I play a video, usually auto-selecting 360p or lower, even though 720p is an option and loads fine when I pick it manually. I have another phone I test this on and it plays HD properly every time so something definitely isn't sticking the way it should.

I'd like to confirm that the youtube app selects 360p no matter what the option for hd videos is but i saw that when first loading the video in vertical display it remains 360p while if you turn your phone horizontal and going fullscreen it switches to 720p instantly or in a few seconds. Maybe it's a feature to conserve data anyway ?

I wouldn't doubt it as we know many have fallen victim to overage fees due to inadvertent and reckless streaming over the years, but if that's the case, this must be a relatively new feature introduced within the last few versions because I never had this issue before. Even before I had unlimited data, I monitored my data usage carefully so I'm not concerned with conserving, and as mentioned, this is happening on Wi-Fi as well. I've changed the settings to always allow HD streaming, but that's not doing anything.
Thanks for confirming though, at least I have a place to start now.

It is indeed happening both on wifi/mobile data with the limit hd videos to wifi option enabled or disabled. I have also tried disabling mobile data while having wifi on and it failed to do HD on start. The difference noted in the post above is that 720p kicks in at about 20secs in the video(check kwabs - walk for testing).
No problem, i just thought of posting to assure you that your device is ok and that it might be a bug/"feature" on google/youtube`s side or some incompatibility with sony(?!). The only thing i can think of is that 720p and higher is pretty pointless in the vertical view with the small video player on top since it's too small to notice which seems pretty logic.
Update: i have deleted cache and data for the app, uninstalled updates, thus reverting to version5.738, restarted the app, signed in and then updated via play store. Now it automatically selects 720p for the video on wifi. It still doesn't matter for mobile data if you disable the limited hd, it shows the 720p but it doesn't autoswitch to it(maybe because i'm on h+ and not on 4g/lte, i can't verify this). Hope it helps ! Cheers !

I hadn't tried clearing cache/data yet, will give it a shot (fingers crossed!)

Update: Ah, you were right about viewing videos in portrait being the culprit. I generally don't watch YouTube in any orientation other than landscape so I never noticed. Basically, the solution is to use YouTube in landscape, or at least, launch the video in landscape. Thanks for pointing that out!

You're welcome ! In my case after the data/cache clearing, uninstalling and updating from store afterwards, portrait videos also start in 720p, the only issue that remains would be the videos not defaulting to 720p on mobile data with the hd limit option disabled.

Good to know. I'm just making sure my phone is in landscape now before I click on the video, problem solved. Such a weird little quirk, LOL!

Tab S2 display "issue"

I'm having an odd issue... Anyone with the 9.7 while holding the tab in portrait view on a screen with lots of text or horizontal lines and plenty of scrolling: while scrolling, does anyone else's display seem to scroll sloppy? The right side of mine scrolls faster than the left. Marginally slower, but noticeable. Makes scrolling seem wavy or wobbly or bendy from right to left. If it's just me, I'm going to exchange this one.
I understand about refresh rates n such. I'm going to Bestbuy today to test the floor model.

OK to update: I tested the floor model at a different Bestbuy than the one I purchased mine at and experienced the same "wavy bendy effect" while vertical scrolling in portrait. So, I'm going to assume it's normal and the refresh rate just can't keep up with high resolution and dpi. In case any other S2 owners see this effect.

Have you show this problem to any of you friends or family, can they see your problem, as some people can be more sensitive to screen refresh problems than others, also oled display can have refresh rate problems.

I have. Unfortunately I'm the only one who can see it. Then again I can spot a dead pixel from 10 feet away. :silly:

I had the original Samsung Note 1 phablet and it had an problem with ghosting while scrolling though menu`s ect, the oled pixels take an lot longer to wake up than lcd pixels, so Samsung sent out an firmware update that kept the pixels on at a very low level all the time to increase the refresh rate and fix the problem with the ghosting.
It been an few years since the Note 1, and oled display have advanced since then, but trying to make the oled displays more efficient i hope they have not turned off the pixels completely or low as they can get away with most people cannot see the refresh problem but you can.
I don't know if this is the reason you are having the problem, it could be something else completely.
Have a look in the developer menu in settings, try the use gpu when drawing or whatever it`s called and see if it makes any difference.

I'm thinking they may have turned them back off. The blacks are very black compared to my other devices. Hmm. I have updated to 5.1 to see if that'd resolve it but it didn't. It's not a huge issue, just weird to see but once I get used to it I'll be alright. Hopefully. lol

Motion Blur is what we called it, not ghosting have a look at the link below, it shows motion blur on the S4 see video, I could not see the problem myself (don't have fighter pilot eyes ) , see if it is the same problem you are having or is it something else.

I'm having issue with screen turning pink when using Chrome as browser. It happens only for 10 to 15 seconds. I wonder if that's hardware or adaptive display problem.

Similar. But instead of it being uniform horizontally across the display, it gets "worse" from right to left more than likely because of the resolution and DPI compared to the S4. But same effect.

That I would say is not normal. Is it only Chrome or are there any other apps that exhibit this color change?

The Tab S has the same issue, but it only happens in portrait mode, seems to be ok in landscape. If i flip the tablet 180 in portrait mode it will do it the opposite way, so its not an optical illusion!
It seems like the control chip for the display is suffering some sort of micro lag.

Have you tried the "forced GPU rendering" in the Developer option, I mentioned in post 6.
John.

Nothing solves it, its just the way it is. I gave up bothering about it and forgot about it until this thread . Another reason to stick with 16:10 instead 4:3.

Indeed. Forced GPU rendering changes nothing. That's one of the first things I tried.

Have you tried playing an HEVC H.265 1080p video yet, to see if it stutters like it does on the S1, the S2 is supposed to have hardware decoding, the S1 uses software decoding that kills the battery and stutters.
HEVC H.265 are half the size of normal H.264 video`s for the same quality.
John.

I have a black and white Tab S2 9.7 and both have the same issue. It doesn't look like motion blur, it looks almost like an intentional wavy/wobble animation when scrolling in any app. Which is why I was looking for an option that toggles it. It's very noticeable by anyone who has used it. I pre-ordered it so I didn't get to test it at Bestbuy before hand. I've never seen this scrolling issue on the old Tab S, Nexus 9 or even an IPad Air 2, I've had all three of them. Just when I think I've found a decent android tablet another issue pops up. If there is no fix and this is considered "normal" then I'll be returning them.

I played a heavy HEVC 4096x1720 and it plays the video perfectly on the standard videoplayer, but it stutters when using VLC so I guess the standard videoplayer has a way to hardware-decode this while VLC-player has to use software decoding?

Very nice, hevc hardware decoding is the only thing i am envious of the S2, And 4096x1720 is amazing, unless it`s only really processing the max resolution of the display, and with the stock Samsung player too, does it support AC3 audio though in the stock player.

The name of the file is tos-4096x1720-tiles.mkv, unfortunately the standard player does not support the used audio codec in that container. When I check the file it says 5.1 sound.
VLC does play the audio but as already said the video stutters heavily.

The audio on that hevc video was AC-3 so it look like only the Tab Pro gets AC-3 decoding

Question Stutters in videos

Hi, I have a problem when I take videos in 60fps. 4k or fullhd.
I always have jerks. An example on this video
At 10 seconds you can see the problem.
I tried to configure in h264 or h265 but it does not change anything...
Thank you in advance for your solutions.

Tried resetting the phone to the factory defaults?

I'm a videographer using this phone. Its a bit frustrating, but i think i know what the issue is. Dont use in built stabilization modes. They work, but they cause frames to drop out. I bought a gimbal system for the stabilization issue ( i needed to buy one anyway ) and the stutters are gone.
