[Nexus 7 General] Ravynmagi:
My Nexus is stock (but unlocked and rooted). I run my Nexus 7 almost all the time at 40% brightness.

I get this over exposed looked after playing most videos. Happens with YouTube, Play Movies, Gallery, pretty much any videos from any source. Turning the screen off and on works. Or I could just wait an minute and watch the screen gradually fade back to normal-ish.

This isn't my only issue though. My screen also seems to be poorly calibrated. Even without the video playback issue, some of my colors are faded, and whites are over saturated all the time.

Don't know if the two issues are related, but I'm going to try exchanging it because some people say theirs doesn't have these issues.

PS. I don't use auto brightness, that makes my screen way too dark (seems my auto brightness setting keeps my Nexus 7 at minimum brightness most of the time).
[Nexus 7 General] :
I have this issue (as well as minor screen separation), but can't replicate it consistently.

I just assumed it was the screen just 'waking up' from full screen mode, it usually goes to normal after about a minute.

Rarely i see a minor screen flicker/ or tearing (sortof like oldschool CRT television flicker on a few scan lines) during this 'recovery'
[Nexus 7 General] mi7chy:
Interesting now that we're on level playing field. Do you have auto-brightness or hard set?
[Nexus 7 General] spovat:
nope. brightness set to around 25%. like others, I can't always replicate but it usually happens after watching videos. locking and unlocking the device immediately restores normal contrast. This is the only semi issue i have on my n7. it doesn't even bother me that much, knowing it's a simple recovery
[Nexus 7 General] sharp2G:
the problem lies within the software. perhaps you're a lucky one who is somehow avoiding this problem or you don't notice the problem yet.

[Nexus 7 General] mightymn:
I have the same issue with my N7. Android 4.1.1 completely stock, out of the box. It seems to be a problem with the hardware decoder as using software in MX player does not seem to trigger it, but the gallery player does. I see this not just after video playback, but around 5 seconds after starting playback when I begin to notice I'm losing so many details in highlights. A white contrast test on www.lagom.nl clearly shows the horrible detail level. I hope they fix it soon.
[Nexus 7 General] saadi703:
I have the same problem but how are you so sure that it is software problem. If it is a software problem then why do you get a screen shot showing no problem when in reality you can see it on your screen that you are indeed having problem on your screen at this very moment.
[Nexus 7 General] saadi703:
Another thing is that it only happens if you watch video in full screen. If you watch YouTube video not in full screen i.e. in portrait then there is no problem of over exposed colors.
[Nexus 7 General] mi7chy:
Does it occur if you watch the free Transformer movie? Just curious since it doesn't for me.
[Nexus 7 General] mightymn:
I can confirm that in only happens in landscape video and yes it does happen with the transformers movie and it's very annoying :(
[Nexus 7 General] saadi703:
Yes, it does. It happens whenever you play a movie full screen no matter what the app is i.e. Google play movies, Netflix, YouTube etc.

Although not a big deal but it is getting on my head and I am considering sending mine back because of this and other issues I am having. At first I thought the only issue I have is the screen lift off but it turns out that it was just the beginning.
[Nexus 7 General] Solange82200:
How long do you have to play it for it to happen? I haven't seen it yet, but let me know how long it takes so I can test and make sure
[Nexus 7 General] sharp2G:
It became more noticeable over time. I'd say around 5+ days for me. I did get a replacement which is expected to arrive Friday.
[Nexus 7 General] Solange82200:
Thanks! But does it happen after playing even 1 minute of video, or do you have to play the video for an hour? Would like to make sure my new (seemingly perfect) replacement doesnt have this issue...
[Nexus 7 General] mightymn:
Mine happens very soon. Sometimes even seconds after going landscape in video. To notice it, I suggest opening chrome and looking at the tab bar color. It is white instead of bright grey like it should be.
[Nexus 7 General] Ravynmagi:
Mine does it even without full screen mode. I noticed it when watching YouTube in portrait mode and trying to read the video description or comments while the video is playing, it's a bit difficult because of the over exposure effect with mine.
[Nexus 7 General] i.amtom:
I get it, waiting a bit solves the problem. I have a feeling its something to do with how brightness turns to full automatically when playing a video in landscape. Must be a software issue.
[Nexus 7 General] miketoasty:
This is your answer right here folks, Metallice even posted a guide to disabling the feature which fixes the issue once and for all, at a cost of battery life when watching videos.
[Nexus 7 General] sharp2G:
i don't see it affecting my battery life at all. I still get 6 hours screen time before applying the fix.

[Asus Transformer TF700] mazuka:
Has anybody noticed the following phenomenon? You look straight at the tablet while holding it perpendicular to the floor at your eyes level.

Then you start tilting it towards yourself - brightness fades at about 45 degree but then returns at about 70 degree and stays at the original level almost to 90. Same if you turn the tablet around.

I would not be surprised if the brightness was gradually fading as the angle increased, but this is the fact that it fades and comes back as the angle increases is what's puzzling me.

Not a big deal, I am just curious.
[Asus Transformer TF700] sapienssapiens:
Color saturation is different when "the angle increases". I suggest you look into LCD polarizing filters. It's probably the screen component you want to investigate in order to understand this phenomenon.
[Asus Transformer TF700] fsured:
Could it be the amount of light the ambient sensor is picking up? If you have it set to auto adjust that is.
[Asus Transformer TF700] mazuka:
I could not find that info related to tf700 screen... even generic articles on IPS and SIPS do not contain detailed description of how exactly brightness changes with viewing angle.
[Asus Transformer TF700] mazuka:
Nope, I have it on manual.

In case you have a tf700 - can you see this phenomenon, or it is just me?

I tried tilting while the screen showing a blank white page - same behavior, and it was almost like I could see some evenly distributed cloudy matter under the screen while at about 45 degree angle, and then the matter disappeared as the angle increased past 45...
[Asus Transformer TF700] mazuka:
resolved

OK, so I wrote Asus on it in get in reply usual "do a factory reset, if does not help - open an MRA";

I still insisted and got in reply something like "in this case we suggest you open an MRA".

I then visited a couple of stores and while I could not find TF700, I examined screens of TF101, TF201, TF300, Galaxy Tab 2, Acer, Toshiba - none had the issue.

At this point mine is going back to the seller.
[Asus Transformer TF700] mazuka:
HELP!

I returned my TF700 and got another one - and here we go, THE SAME issue - I tilt the screen - brightness fades at 45 degree then returns at 75 or so.

Dear FT700 owners, take a few seconds, share your experiences with me, I do not believe I am the only one having this issue.

ASUS folks, I would really appreciate if you chime on this too. If I return my second TF700 - I am done with ASUS tablets in general.

I went through blurry TF101, not working TF201, and now two TF700 seemingly having a display issue, and this is while the display is the main selling point of the unit.
[Asus Transformer TF700] jtrosky:
Yes, my TF700 does the same thing - I believe that it's completely normal....
[Asus Transformer TF700] Cleanskinned:
My screen constantly adjusts brightness, but it has nothing to do with tilting the tablet. I can hold the tablet completely still and the brightness continuously adjusts, especially while watching videos. I must admit that it does get distracting as it happens every couple seconds depending on what is shown on the screen. I have autobrightness turned off.
[Asus Transformer TF700] mazuka:
Thank you, jtrosky. Anyone else?
[Asus Transformer TF700] mazuka:
Try cold boot, then try factory reset, and if no results - send it back to the seller.
[Asus Transformer TF700] jtrosky:
That is the dynamic contrast that you are speaking of. Basically, the tablet increases and decreases the backlight depending on how much white is on the screen, etc... Annoying, but it also helps make the screen look good (super high contrast)... No way to disable it yet though...
[Asus Transformer TF700] opentoe:
What? Nothing is changing on the screen so it can't be what you are saying. If the screen is displaying STATIC content it should display the same brightness no matter how you are looking at it. As I said before in a previous post, it is manufacturing of the cheap screen. How else do you think Asus made the Infinity the same price as the Prime? They had to take shortcuts and use cheaper inferior parts. Sorry.
[Asus Transformer TF700] jtrosky:
Saywhat? The poster that I was replying to said that it was most noticeble while watching videos, not while the screen was static... Of course it's not auto-contrast if the screen is static!

Please actually read the posts before making stupid remarks!
[Asus Transformer TF700] Eroc162:
I use Vplayer and Diceplayer which have the gesture controls to max bright the screen and Volume control. When I'm watching a movie I set it to high and I never have an issue with it dimming. Try it out.

I think it overrights the light sensor.
[Asus Transformer TF700] jtrosky:
So you are saying that you set the brightness to max and leave it there while watching a video?? I think that would be way to bright for most movie-viewing scenarios!
[Asus Transformer TF700] sapienssapiens:
Oh man...I thought you wanted to understand the science behind the phenomenon, not that you percieved this as a problem.

This is normal. There's nothing wrong with your screen.
[Asus Transformer TF700] BeverageNinja:
^This

While there are some very valid issues being reporting, this isn't one of them.
[Asus Transformer TF700] emmemm:
I also have a "brightness flicker" issue.

Even on a screen that does not change at all.

I just have to open google maps.

About every 2-10 seconds there are one or a few flickers.

I tried different power saving settings and disabled auto adjust brightness.

Screen still flicker.

I just have received my tf700t and have not yet noticed this flickering in other apps.

emmemm
[Asus Transformer TF700] uwotm8:
this is normal, i noticed this too, when you go into a video it flickers and dims down but when you go back to the home screen it flickers back to normal, this is the contrast system not some bs about a cheap screen used by asus.

+1 - disable the "SmartDimmer" and this issue goes away.

There is a great Sticky in the Development thread and gives you exact procedures in order to disable this and keep it disabled after a reboot.

Lots of other goodies in that Sticky post as well (tune auto-brightess levels, performance tweaks, etc).

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] A San:
I've already tested with copy, delete, rename & change file properties at system files.

It will work temporary only if I do a setting on "ES File Explorer" application. I have to go to setting and uncheck and check the Mount File System (Mount / . / system as writable).

But it worked only temporary, the file properties will back to before, only copy, delete, rename files still remain.

If after sometimes, I want to copy or delete or edit a file, I have to do the same procedure again with the help of "ES File Explorer" app.

The problem is, the file system cannot be changed if using some program like Volume+, CallRecorder, so the application didn't effect, even with the setting above.

Note : I've already checked with Root Checker application, ant it's said "Already Rooted"

Now I am using ICS 4.0.4 official for my Galaxy Note.

Ugrade from Gingerbread to CS with Mobile ODIN from Play Store.

Any suggestion which I can do to set the system, so it won't always return to lock the file (not editable) ?

[Vibrant Q&A, Help & Troubleshooting] Jsfuga:
I am trying to flash my vibrant to stock, but my laptop says usb unrecognized.This causes Odin not to detect my vibrant in download mode. I have downloaded all drivers including nexus drivers, but still same error usb unrecognized. I have then start on switching data cables including the stock data cables but the errors remain the same. I have tried on different computers and different windows, nothing working its the same errors on all computers. I have messed up by formatting everything in the Vibrant, now it boot loops to Vibrant logo. I can get into download mode normal but I cant get into CWM or any recovery mode, its probably because I have formatted the whole phone. When the phone is off, I plugged in the micro USB to the phone from the laptop, all it shows is the white lines that are in circler motions and then freezes. Weird my laptop still detects it as a USB unrecognized. As the phone is plugged in to the laptop I try taking the battery out and my phone is still on with the frozen screen of those white lines in circler Motions. Can anyone help me, or at least explain to me what the problem may be? My thoughts is that it may be a hardware problem. If so can anyone provide me some schematics on the USB portion? I hope we can bring some light on this problem. Giving it to T-Mobile is not an option. I have dealt with many problems and solved it, but this is one problem that keeps me stomp in my own tracks.

You can give a man a fish and he will eat for a day, but if you teach a man to fish, he will be able to eat for a lifetime!
[Vibrant Q&A, Help & Troubleshooting] Woody:
Ok, so I am in a similar situation as yourself. I bought another Vibrant that was stuck on the bootloader screen. I gets into DL mode just fine, however Odin doesn't recognize it. I have uninstalled, reinstalled the drivers, used Nexus S and GNex drivers, 4 cords and 3ports and still no joy. My daily driver Vibe is like a mid-town flasher and is seen all over the place. So this leads me to believe that it is not driver/SW related but rather HW realted for me.

I think that my next step is to clean the USB ports on the phone and see if that works. If not, then I'll have to probably crack her open and clean there. I have another laptop that is using WinXP, so I might give that a try since nothing Samsung has ever been installed on it.

Keep me up to date with your findings and I will do the same with mine. Clearly I am not a noob but now this is just making me mad. Why one phone works/is seen and not the other. Common denomitator has to be HW.
[Vibrant Q&A, Help & Troubleshooting] Jsfuga:
I agree with you, it may be a HW issue. I have tried connecting other phones to my laptop and it reads it just fine, but for my vibrant no success. Im gonna go ahead and actally open it up and check on some componets, i have a feeling that it may have burnt one of the componets due to over charge. Ill get back with you on my findings. Keep me updated on your progress.
[Vibrant Q&A, Help & Troubleshooting] Woody:
Before you open her up, have you tried cleaning the metal contacts inside the USB on the phone? I am at work not, so I can't try anything, but I would check that before opening. Might just need to be cleaned.
[Vibrant Q&A, Help & Troubleshooting] Jsfuga:
yes i've tried. I used a Q-tip and some alcohol, still same problems.
[Vibrant Q&A, Help & Troubleshooting] Woody:
Update: Nothing!! How about you?

I have tried un/reinstalling the drivers, Odin v1.8, 1.3 and 1.0, about 4-5 cables and all 3 ports. I have cleaned the USB with alcohol and at this point am at a slight loss. The phone boots into DLmode and charges fine, so I don't think it is a faulty USB port. I cannot get into any recovery or ROM boot. All I have is DLmode and the GB bl screen. No kernel or ROM splash.
[Vibrant Q&A, Help & Troubleshooting] Xenoism:
Gasp! I'm in a similar boat guys. My phone charges fine, and all my drivers are working and up to date...I can get into DL mode and all that jazz...phone even boots up and works! (fortunately)...but no dice on it being recognized by my or any computer. Glancing into the port, it looks like there may be some corrosion on the left hand side of the port, or some sort of damage...can't really tell without a proper magnifying glass. but it does look damaged or at least irregular. I've been reading around, and cleaning sounds like a potential solution...I've no idea how you guys are cleaning with giant q-tips lol but hopefully I can figure that one out also and give it a whirl xD But in the mean time, I sure hope somebody can come to the rescue ;)

[Sprint HTC EVO 4G LTE] JoeMimic:
I've got a stock Evo 4G LTE, never been rooted and I got it via pre order directly from Sprint. Never had a major problem until last night. I went to check a message on my phone and the screen is/was frozen. I can't actually unlock the phone via the launcher. Now if I press volume up/down the normal volume screen comes up and accurately shows the volume doing whatever way I'm pressing it. Power button press turns the screen on and off as usual. It's as if my phone has lost the touch screen functionality and is basically useless at this point. I've restarted it probably 10-15 times. I let the power die and then tried to see if it completely dying would fix it and nothing.

I got a tad desperate this evening and I accessed the recovery menu and did a factory reset...comes back up but the problem is still there. I can't unlock it and actually get into my phone. Anyone have any ideas? I'm pretty resigned to the fact that I'm probably going to end up at a sprint store tomorrow but I just want to see if anyone has any last ditch effort ideas.
