Does anyone else have this problem with their nexus 7? I just got my nexus 7 today but I noticed that the backlight seems to flicker randomly
It doesn't look like much in the video but it is very noticeable and gets annoying when you're reading an ebook like i was.. Here's a video showing the problem.(It's near the end)
VIDEO LINK: h**p://db.tt/28eD0NLk (It happens around 9 second in) (change ** into tt)
For whatever reason this forum would not post a video link to show the problem.. for those who wants to know what it looks like please PM me..
But basically the screen flickers randomly ..
Is this a software problem? Should I go back and get it exchanged?
I don't see a video

I think its different.
Mine flickers no matter which app I use..even on home screen it flickers..
Also this forum has the most ridiculousspam prevention method..5 mins between posts + no link ? WTF
Its because you are new, we get a lot of trolls
Does increasing your brightness help?

I've had a similar problem as well. It seemed to happen to me on auto-brightness when it was changing the brightness level. I can't say for sure though, just my observation.

I havn't tried it yet..do we know if it's a hardware problem or software?
I just got it today so I can still return it if it turns out to be hardware
We really dunno at this point, but we are speculating software since both HTC One X and TF300 had similar problems and were fixed with firmware updates. Also someone switched it three times and all of them had this issue. Also try to run the screen in a pitch black room and tell me if the screen flicker is there. I may have a theory but need some other people to see if their units are behaving the same way as mine.
You can still post the link when you alter it a bit, insert a few *** into it, for example.
I turned mine on as soon as I got hold of it, no flicker, managed to go through and set up things, powered off and left to charged.
Coming back to it the screen would appear to turn on and off randomly, I thought it could be an app controlling a proximity sensor (I have one on my phone and I was EXTREMELY tired!), when I took it into the light there was no change.
I found that shaking it would help it flicker on and off at all intervals but didn't fix it. In the end I just started pushing random areas on the back, just before the issue went away I pressed around the bottom left quarter of mine and haven't had an issue since!
Glad I wasn't the only one with the problem though and would love to actually find out what it was.
Hope this helps!

Try this video,
h**p://dl.dropbox.com/u/13153603/Videos/VID_20120715_100253.mp4
it is using google map and you can see the constant flickering.. It doesn't look very severe in the video but it is actually very noticeable and annoying
I have the same issue with mine. It only seems noticeable when I have the brightness set to the lowest setting and on a page that is predominately white. I don't think it's the proximity sensor though, because it happens both when I set it manually to the lowest setting and when I'm in the dark and the tablet sets the brightness all the way down itself. Hope the next update fixed this, because it's really annoying!

Seems like only a small portion of nexus 7 owners are reporting this issue .. I think I'm going to return mine ...

I first noticed this flicker in a darkened room, so yes, it is definitely something going on. I'll try disabling auto-brightness to see if that matters.
If anyone else has info about this, please share!

I can attest that the flicker is ever present in a pitch black room as well.
Like this?
There are a few videos on youtube, but i cant post links but if you do a search you can find it
I noticed a flickering in chrome yesterday. But only in chrome and only while the page is rendering after it fully renders no more flickering.
Everyone turn off wifi and I guarantee it will go away. It happens when using wifi which makes it hard to believe that a software update can fix it.
Hello,
I picked up my GS4 about a week ago but haven't really used it in direct sunlight until today. I was outside, and the sun was shining brightly on the screen. Home screen was fine, and darker images were ok, but if I were to go to an app with a primarily white background, or open up something which used the keyboard (texting) the screen would flicker pretty noticeably. Brightness is all the way up, and auto tone was off.
Has anyone else seen this?
yup this is normal esp when using the keyboard.
Im not sure if it will be fixed.

I guess my question is, is this a hardware issue with many GS4's or a minority. I came across a thread on the Tmobile GS4 forum where people were experiencing it, but it seems not everyone is.

Its a hardware thing, but also its only in touchwiz so a developer might be able to turn it off so to speak.
It adjusts the color and tone no matter what to save the display from overheating and or burning in...
Does it a lot and I notice it cause im weird about those kinds of things.
If you use CM 10.1 or AOKP its gone.
ive made some progress with the RGB light meter on this; hoping a friend can write up some code so we can test out a 'smoothed out' transition and sampling rate and one that is sped up, averaged faster, but will take up more CPU and RAM and battery but more accurate.
here is another thread regarding it:
http://forum.xda-developers.com/showthread.php?t=2280715
http://forum.xda-developers.com/showthread.php?t=2284726
Maybe if someone who is using CM10 or AOKP could test it to see if it is a software issues and not a hardware issue?
edit: slade and jet replied while I was writing this...thanks for the info. looks like it is touchwiz related.
edit2: just went out in the sun again to test a lot of different options in the display settings (which none worked) but is seems it is only happening when the keyboard is enabled. I am using swiftkey.
yeah TW and that sensor communicate; i believe the sensor itself probably works better ALONE, but TW changes it and throttles it for either battery or screen safety.
It is always dependent on what is being pulled up on the screen, though it can be mitigated quite a bit if you disable all power saving and screen auto features, and leave brightness under 80% or so.
yea anything under 80% in direct sun is basically black. all power saving and screen auto modes were disabled. i covered up all of the sensors too and it still flickered....

Not just a sensor thing per-say.
It's hard to explain, they most likely did it because they didn't want the amoled to burn in.
Its the same reason why the brightness goes up another 34% or so on auto above the max brightness. Only uses it when needed to save the screen and battery.
Does it on youtube too btw, bring up a video on wide screen then tap it and you'll see the drastic color shift
I noticed this thing when I got my phone also. I thought I was just imagining it but I guess it's an actual problem

Seriously its about power handling/battery saving and white balance, but its noticeable, and annoying.

No that's not possible, its hard coded into touchwiz, this isn't a bug or anything...
If people say they don't have it; they're not noticing it.

Thought my eyes were going crazy. Mine does this too. It even did it once under some fluorescent lights. It's not annoying enough to matter but it would be cool if it gets fixed.
This phone is amazing! I can't say enough good about it. I did find a bug that I wonder if anyone else has noticed.
I like to turn all animation off just for more speed. When you turn it off, transition animation comes back on after a little while. Maybe after being in deep sleep. Minor annoyance and it'll get fixed. Anyone else have this issue?
Yeah I read about this in another thread. It does seem to be a small bug. I believe they said in the other thread that the it kicks back in after u use camera.

Thanks Kevin,
Yep, I can confirm now. It's after using the camera when it happens. Thanks!
adaptive display off
reading mode off
brightness manual
smart screen off
brightness level set to 90% or so
and my screen auto dimm for no reason playing PVZ or any other game is very annoying to the point of stop playing
I did some reading on att note 3 forums and they said this is implemented on the Kernel itself so if we can get full unlock perhaps we can use a custom kerlel to fix this BIG PROBLEM

sorry if I was not clear with all those options turned off the screen keeps auto dimming during games so there is nothing you can do to keep the screen at same brightness what is unacceptable

Ahh, gotcha.
I've never experienced any problems with the screen dimming when I'm using it (even playing games). But I like to use Smart Stay (works great for me) and I like my brightness at 100% all the time, so it's a little different scenario, I guess.

I've seen it and been looking for where to turn it off. Was going to post about it, so glad you did. It's very annoying and send to happen at odd times in pretty much any app.
Now here's another one for you. Have you noticed when you pick up your phone that it will vibrate twice? I can't tell what I'd doing it, so it may be a system thing.

Yea if in the next update it don't get a fix Samsung will not like me very much
Like how LG probably hates me every chance I get I talk **** especially about their LowGrade ****uition
Android product ...LG is byfar the worst android creators out there and should just stick
To making ****ty appliance or better yet just stay out of the electronic world all 2gthr IMO...
But back to the subject at hand it seems its when a lot of processes are going that it dims (CRASHES)
Try keeping an auto task killer app running to kill unwanted tasks as they pop up...
It works but not for too long. it would seem the 2G of RAM is not enough for the quadcore
maybe 3G would have worked better.
Solution
Kinda late with an answer but I figured out why my note 4 was doing that out of the bloom. Turns out I had an option checked for my screen brightness to adjust based on the image that was on my display. Just go to Settings, Display, then uncheck the Auto Adjust Screen Tone. That should fix it. ☺
Hi lovely guys of the Note 3 forum!!
I've had my Note 3 for some time now and I was wondering if my screen is defect since it does act a little weird. I hope you can clarify this for me
Whenever I put my screen on low brightness, the screen tend to leave a trail of purple color behind whenever I scroll/move something. It'd be very nice if anyone with a Note 3 could test this for me, if u are having the same problem or if it's just me
A good way to test this, is to set brightness to 0% and then pull the notificationcenter down and try to swipe the notifications away slowly and look closely, if u can find some purple trail leaving behind the swiping object. To see this clearly, you can download the app Lux and set the brightness to sub-zero. Try -50% and it should be very easy to see. Would mean a ton to me if you could report back. I need to return my device asap if it's defect.
Thank you very much!! <3
EDIT: Here is a video of the problem!

Hey guys!
Just to confirm we're talking about the same thing, here is a video I took of the problem
EDIT: Seems like I've discovered a general issue with S4/Note3; Ghosting/smearing. God damnit, this is annoying. The shop will probably not even take it back now. ****..

I can't see this at zero brightness. I even installed lux and set it to subzero, and I still can't see it. I'm using an SM-900T.
I think I know what you are talking about. I also believe my smartphone has same problem. As an example if you download BBC News application,then scroll down to end of page and pull further you will see this tail of light appear. It also does this in the settings page when you scrol up or down but you have to get to bottom or top of page and pull further

Not sure if that was sarcasm... BEcause I hope it was.
That's the replacement for the 'bounce at end of page' that Apple successfully sued Samsung over. It now glows.
exactly the same problem with mine. fast moving UI elements leave a purple trail behind them.
could it be that some batches of screen are affected and some are not? it doesn't bother me too much though.
