I notice that the screen on my nexus 7 flickers at regular times at brightness levels lesser than 30% or so.
Here's what I tried:
1. Disable auto brightness
2. Installing lux and turning of auto
3. Factory Reset
4. Wifi Conservation-turned off
Still, it's not going away. I'm running Android 4.2.2. It does not appear to flicker at subzero levels on lux.
This is a new Nexus 7 and I want to ask whether I should return it( If it is a H/W problem) or it has some S/W solution?
Also, this is sorta a medical question: Is it unhealthy for your eyes to use subzero brightness?

My opinion, I would return it. I had this problem when I got my n7 on its first release but it went away after the updates

I'm on the latest version of android. So it is a H/W issue? I need to return it soon then.

Have you tried turning off smartdimmer?
I'd send it back mate.
Even though some of these suggestions may fix your issue, thats not the point !! You shouldn't have to disable anything to stop the screen flickering.
RMA it.
I sent mine back for service yesterday.

It's hopefully fixed after turning off Tegra PRISM.
I can't notice any flicker now.
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

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.
Alright so I just got my Note 3 here in Canada (SM-N900W8) and whenever I download an app from the Play store, or do anything I would normally do on a S4 or HTC One, the phone lowers the screen brightness (usually keep it on full brightness). When I go into Settings > Display > Brightness, it says something along the lines of to ensure your phone doesn't over heat, your phone's brightness has been lowered. Now, I've noticed this happen a handful of times, and I'm wondering if anyone else is having this problem?
I don't think the phone should be doing that over simple task like downloading apps. Might want to take it back asap and exchange for a new one.

Yes, mine is doing the same exact thing. When it first started happening, I thought there was something wrong with this particular phone but then I saw that same message. It's annoying have the screen change brightness like that.
I notice when browsing web page it does it too.. can anyone else confirm? Test by turning your brightness all the way, then download a few apps and browse the web. Let me know.
same experience
Hi! Very new at this forum. Just searched the net because of the same problem. The screen keeps dimming even if im using it. I thought it was a problem so I had my unit replaced. I have a new one now but it still does the same thing. It still dims randomly. Now I dont know if I should have another replacement or if this is normal.

I think the dimming may be caused by settings>device>display>auto adjust screen tones. And/or screen mode check anything but adapt mode. .. That solved it for me.

And here's the link to that thread... http://forum.xda-developers.com/showthread.php?t=2382134
I haven't got the Note 3 yet partly because of this. When I compared my Note 2 to the Note 3 in the At&t store I noticed the Note 3 was definitely not as bright, while being obviously bluer. But I also caught it dimming itself too, very quickly but couldn't get it to reproduce the behavior. Changing the display mode didn't affect any of this. I've wanted to see this amazing improved display everyone talks about but I haven't seen it yet - certainly not when the brightness is set manually.
I wonder if this dimming display thing is a new normal, that they've made the brightness more an automatic control now. I have no idea if this is to save battery (but then why not let the user choose) or if these new screens need to be protected more from overheating.

What's the point of full brightness if it's going to auto-dim all the time? I ended up returning my Galaxy Mega for this very reason.

What parts of the phone heats up? Mine is near the camera. But I havent had this message yet on my note but it does get fairly hot alot. I dont even do anything for it to heat up this much. Just browse around and dont play much games.

I'm on my third... and posted already in your thread! for me this throttling happens all the time, gallery indexing for example triggers it a lot!
to clarify:
this throttling has nothing to do with settings a user can adjust, it's logic must be kernel implemented! no auto-contrast setting would help! and it happens even when you are on manual lowest brightness. on my devices the screen would switch even then in a cycle of ca. 20s between a additionally dimmed and the set state...

Hi,
Have any of you noticed when you push the home or the power button to turn on your phone to unlock it the screen is really bright for a second then it switches to your settings? Has anyone experienced this and if so has anyone found a way to stop it?

Nu such issue on mine. Might be because of auto brightness, the sensor is off when the screen is off.
Yes. I have see this issue in my brother in law note 3. We all bought 3 note 3. 2 of it doesn't have this issue. I wonder is it hardware issue? Since the other two phone will never having the brightness problem.

I noticed this on my Nexus 7 2013, it's really annoying when you want to say read in bed and the lights are off it's far too bright. I found using the app Brightness Adjuster solved this. It lets you go way below the firmware level of brightness and I have found it excellent. May work on your NIII.

Huh? Wha? That's a fix for screen flickering?
Op, search youtube for S7 Edge screen flickering and be amazed! Brand new S7s were doing that.
If you slide the brightness to max, it should stop. Or if bright light hits the dimming sensor, it stops.

Most likely an issue with the AMOLED PWM implementation/controller, the flicker free Kernel doesn't use PWM to control Brightness.
So this might be an suitable workaround for users without warranty or possibility of repair.
