Weird Screen Problem? - Nexus 7 Q&A, Help & Troubleshooting

So yeah, was just using my N7 about 30 minutes ago. Just picked it up and the screen won't come on. Happened earlier this week too.
The weird thing is, my computer still recognizes it (obviously the tablet is still on) but ADB doesn't seem to notice it. Any ideas?

It was connected on computer or power?

Neither it was just sitting on my desk. Just got it to reboot after 10+ times. Really wanna know what's going on, because it's annoying as hell.

I recall seeing another thread about this. Disable auto-brightness. Your screen is on, just that the brightness is turned down completely.

Hmm, turning auto brightness off. Let's see if that'll work. Thanks for the help.

issue with backlight will charging

I've been noticing it happening more recently. when I connect my phone to my charger my phone tends to wake itself up. I plug my phone in and my phone is off or asleep. after about maybe a minute to 2 minutes the screen will wake up. I look in the options and have the option to keep a light on unchecked. my backlight timeout is set at 30 seconds, yet I've counted over 2 minutes where the light stays on until I manually choose to turn it off.
I don't like leaving the phone screen on because it can damage the screen. I can't quite figure out what could be causing the issue. I've done absolutely no modding to the phone its completely stock. I have got the j16 update but this is a more recent issue I'm experiencing.

Epic just died.

Just now. I was on xda app and suddenly the screen started having a titty attack (its happened numerous times before on froyo)
i wasnt worried cuz i figured my processor was just being overworked so i downclocked it to 400mhz.
Usually this happens in miren or dolphin. Then it clicked. It MUST BE ALL THE ENERGY BEING USED TO RENDER THE WHITE! cuz i always use my [phone at or near max brightness....
the thing was, i lowered the brightness and it stopped, but then it just shut off....i had to unplug it and plug it back in for the charger to even start charging it again.
So my question...is the screen dying (which means it has been for a while.) or is the processor dying (which means it has been for a while lol)
just wonderin are you using a stock battery or a cheapy from ebay? i had this happen too, and it turned out to be neither the screen or the core. it was only happening when i was using my aftermarket chinese battery.
im using stock battery
maybe its not getting enough juice anymore? i do plug my phone into things alot...lol

I had a screen crap out on me. I had similar symptoms leading up to it. The next thing that happened was the touchscreen became unresponsive unless keyboard was open. Then it stopped altogether. Thank goodness for my insurance because it did die. When I took it to a Repair store they had to open a new one to replace it because it is not a common issue.

How bad is it, I know we can all experience the screen f'ing up just by raising the brightness all the way and go to settings>display>and uncheck power save mode then go to any screen that is white. Its a problem with the super amoled.
But if you have the power save mode thing checked I think ur f'ed

This has happened go me before. But it was because I was trying to flash roms over a custom stock rom and I didn't know. I suggest you Odin back to stock. Leave it for a week or 2.

My screen flickers really hard on all white pages when the screen iks on full bright and power save off. Not all the time though, only when my battery is under 20 percent or so.

Similar experience but usually only when under 10-15% battery left and full brightness. The screen just can't draw enough current I guess.

I hardly ever get below 25% on a battery because I carry a backup but when I did, I had strange things happen.

Ohhhh, well that's interesting. Because if you OC or if your phone heats up enough data corrupts and your screen spazzes out. But I wonder if weather could play an affect towards that.

Its funny you mentioned that. It was 103 degrees in SoCal yesterday and I was getting random reboots and freezing ON FROYO and that never happens to me.

My screen goes glitchy when its on 100% brightness, and I go to a mostly white app(like google search), but its cause mines a refurb.

[Q] Is my screen broken?

I got my Nexus 7 about a week ago and have been loving it. However, I woke up this morning to turn the screen on and it is not turning on at all. The screen stays black, even though I had it plugged in all night. When I connect it to my computer it makes a sound which leads me to believe that the tablet works, but the screen has unexpectedly died on me. Are there any tricks or tips you could give me on how to possibly get it to work, and if not where do I go to get it fixed (Ordered from Gamestop.com with store credit, 16 GB model).
Have you tried holding the power button on it for around/over 30 seconds to force it to power off and back on? I had the same problem with mine, and doing that fixed it.
I had the problem. Hard reboot sorts it

Hi all,
My Nexus7 screen will automatically dim out while watching movies through apps. It will dim until all dark and i donno way to turn the screen back. The movie is still running though with sound on but no screen. I didnt turn on auto brightness. does anyone's N7 has the same issue i am having? How may I fix it, thx

No one has screen dimming problem?

I don't know if screen flicker and screen dimming are the same thing but I encounter a similar issue whenever brightness is below 30 percent.... Other than that my Nexus is flawless besides a rare notification freeze

So, if mine is also called a screen flicker, how do I fix it?
When my N7 screen went all black out, I have to use a torch towards my N7 screen sensor to have the screen bright up again

I just got mine yesterday. Not rooted but I noticed if the screen auto turns off....sometimes it is locked up. Hitting the power button won't do a thing. Have you had this problem?

Yes, i have this problem too. Then when I have no torch beside me for the sensor, i would need to press power button for 10sec+ for a reboot. How suck it is. This is the only thing bugging me on N7

I just got off the phone with Google play. Having a new unit sent to me. Glad to hear (unfortunately) you are having similar issues.

So, no one seems to know how to fix, then it's hardware problem and have to send to ASUS?

hey!
if it is the same issue as i have (screen turns off in auto brightness or manually set the brightness to minimum), i dont think it is an hardware issue.
i think the minimum background light is set wrong in the system.
also i dont think it is hardware related, because many other owner af a n7 are reporting this issue.

So is that means only hope is hope for next firmware fixing it?

i dont know... if so, i hope for a quick fix
but you could try the app
tegra prism toggle
(costs about 1$, needa root)
maybe it helps
testcenter, thanks for the recommanded app, but i not wanna root at this moment.
I guess in the mean time just not using auto brightness and pray for not dim out again

Brightness Slider Gone

I'm rooted running stock with no mods flashed and I'm not sure why but sometime over the past few days my brightness adjuster has disappeared from my notifications. I enjoyed having it there and if it's just a setting I've hit that's be awesome. Otherwise I might just flash a rom to fix it.

You can see if it is turned on.
Click on settings
My Device
Display
Notification Panel
Then click Brightness Adjustment
If it unchecked that is why you don't see it. Unfortunately I have no clue why it turns off if you are not doing it.

Thanks lol. I looked for a setting but evidently I didn't try hard enough.
No problem, Samsung had to move all the settings around in 4.2, making it harder for everyone

It disapears when your battery hits 5%
Comes back when you are at 6% or higher

please help *my brightness adjuster has disappeared,
I have it enabled in the settings
Yeah mine has disappeared too, this is the second time I reset my phone once and it came back now it has happened again. No one seems to know why...
Night Mode
If you have the app Night Mode. Turn it on (start) then turn it off (stop). The slider should appear again, as long as you have it checked in the settings.
