nexus 7 screen flickering

So this only Happens when I'm on Google chrome and I've noticed that ocassionally that the screen flickers, its not crazy annoying but definitely distracting. Have any of you had this problem?
Hopefully any of you aren't epileptic.

Hopefully the next update will resolve this problem.

so set and wait.
So I should just wait for a fix and not return it over and over to try to find a good one. It has a year warranty.

I see it too!

I turned off automatic brightness and I think that solved it. I think it was flickering when it was changing brightness.

its still there with auto off.
And with the brightness up but it so slight u have to be ocd like I am about my stuff to see it. But its easy to tell its not hardware because games like sonic CD are beautiful.

It happens to mine when its on the lowest brightness setting of when "auto brightness" is on. For now I've just set the brightness to max so I don't have deal with all the flickering.. for now.

With my settings set to Automatically lock (immediately after sleep) and power button instantly locks with a visible patter screen lock, my Nexus 7 on wake-up [pushing the power button immediately] either right after an invalid pattern code (where device then sleeps) or waiting a few seconds with no activity until the device sleeps (where the Nexus 7 fades to a black screen) will have a delay in bringing up the lock screen OR sort of flicker presenting some sort of black and white bar lines background at the bottom half of the screen for a split second before bringing up the lock screen. Is this normal or it is in fact a defect?
Thanks in advance!

Not sire about that I have seen it in 3rd patty apps on all devices before. But the flicker we are seeing is like it changing the brightness up and down.

As does mine. I think people think it goes away when not on auto, because the "low" setting is about 20-25% and auto will often bring it lower than that, making the flickering worse.
At medium brightness the problem is almost, almost, non-existant.
It's also not just in chrome as some say, just most noticable on chrome's white backgrounds. I've noticed it in any app with lighter, brighter colors. I just exchanged my Nexus 7, and the new one has the exact same problem. This leads me to think the software problem is the most correct answer.

I get it every once in a while. Full brightness set, no automatic. Ill wait for a fix, doesn't bug me too bad.

I suspect it to be a software problem because in game it looks great. Plus in a new device like this software problems go with the territory.

And mine as well I noticed my screen flickered when my batt was getting down to 10% and my brightness level was at about 1/3. But now its charged and I don't see it flickering yet. I don't know...with Chrome having a bug (lags when scrolling) and the flickering screen...I may be returning my unit? I really hate to because aside from my issues, it's an awesome device!

Don't take it back they well fix it with a update.

Using the Nexus 7 in the dark

I seem to have found a weird problem with my Nexus 7. I can't wake it up in the dark. If i turn on the lights in the room, the nexus will wake up when i hit push the power button. I can recreate the problem in a lighted room but putting my covering up the camera and light senor. If i turn off the "auto-brightness" feature, It works like normal.
Anyone else having a problem using the Nexus 7 in the dark?

Auto brightness is pretty buggy currently.

True that. When I put mine on auto, it just stays at the lowest it can go. Doesn't move no matter what.

I ran into the exact same problem. I wonder if it is just our tablet. Since I was not sure if this is a hardware issue or a software I started a RMA.

was just about to start a new thread asking about this issue...
well, at least it's good to know that I'm not the only one experiencing this defect.
I wonder if this is a hardware or software issue.

I cover up the light sensor and it wakes up like normal and very dim. Remove my hand and it brightens as I would expect.

You may want to check out an app called "Display Brightness" by Big Rubber Pepper. It will also save you battery by allowing you to control your brightness from 1 to 100% with the swipe of your finger with an invisible slider at the very edge of your screen that can be customized for any location.

yeah this bug is annoying me. Hope they fix it soon.

Powers on fine here with auto-brightness in complete darkness. Return it to stock to see if it clears up.

I'm getting this too. Also if I manually do the brightness slider all the way to the bottom the screen goes off.. I thought it was bricked at first then turned the light on and hey presto! I'm running a stock rom but its rooted, deodexed and also running the tablet ui patch (dpi set at default 213).

Just an update... I got the replacement and that Nexus 7 tablet doesn't have the auto-brightness issue so I guess it was a hardware problem and I am glad I did the RMA or else it would have kept bugging me

Also finding the auto brightness to not work right, one of the applications I downloaded showed the sensor bouncing around a lot. I picked up Lux brightness and it seems to do a better job of moderating automatic brightness with the ability to set custom levels based on the ambient light.

I've never noticed my screen "flicker"; does it flash off and on again or what?

Yeah, please clarify what a flicker is... if it only happened a couple times then it probably is related to the apps or maybe a couple things going on at once.
If it is not a constant, consistent problem and had only happened a couple times then perhaps it isn't a problem at all.

My screen flickered for a good 5 minutes and even a reboot didn't fix it. I think it's hardware related because if it was software a reboot would have fixed it. Could have been a driver glitch too but I'm pretty sure a reboot would've fixed it. My flickered a lot though saw a bunch of vertical lines and discoloration. Idk if that's what you're talking about.

I use Google Music a lot and I've never seen that. I just tried to replicate it and other than the usual CRT off animation I didn't see anything that I would construe as a flicker or flash.

If you hold your device in front of you with the screen on and look beyond it (i.e. over it's shoulder per say) you can see flicker. Works best in a dark room.
No big deal, but it's there.

I think its a big deal ...you spend your money for a working product..these issues need to be addressed..I thought I could trust LG again but dont think I can anymore

This sounds like a refresh rate issue, which would be hardware, yes?

Sounds like one of those magic eye pictures. If you squint at your screen while holding it at a 45-degree angle in a dark room with brightness turned all the way down and jog in place...
I'm not sure how to replicate it based on what you said, but I still don't see any screen flicker.

Mine started flickering like mad today for the first time. I rebooted, but that didn't fix it. I started up a benchmark app and the flickering stopped after the graphics benchmarks ran. I had to RMA my first Nexus 7 with screen issues too, so I'm hoping this is just a software issue

I don't have this issue at all.

GREEN TINT IN S4 i9500

I am using my s4 from past 20 days but today i noticed whenever i open keyboard to type something a slight green tint occurs on the display it is very visible while using the phone in dark environment with zero brightness and with higher brightness levels its not that clear but still it is there ... i got rid of smearing issue courtesy screen adjuster app but this issue is bothering me .... anyone else having the same issue plz let me know.

Sent from my GT-I9505 using xda premium

I'm having this issue and it's doing my head in!
Every time I bring up the on screen keyboard the hue changes slightly to greeny tone. Then back again when keyboard goes.
I'm surprised not more people mention it.
The easiest way I found to see it was ten brightness right down, go to a dark room and open play store. Touch on the search bar to bring up recent searches and keyboard, then hit the back button, then touch touch bar again, then the back button. Keep doing this so your toggling keyboard on and off and watch the whole screen shift tone.
I'd love to know if it's an issue across the board or if only a few phones are affected.

I am facing the exact issue bro but i hope it will be a software related issue but i am also worried that may be we have defective handsets because very few people raised voice against this issue so it means that most users are not suffering from this issue.

It's got nothing to do with the keyboard.
If you watch a movie on you tube (black and white is best) put to full screen and wait for slider to dissappear, then tap screen to bring it back. The hue changes to green!
It's whenever the screen has to bring something up like a keyboard, menu, slider etc.
Come on guys please can you test this so we know it's a problem on all handsets like smearing or if it's a hardware fault in a few handsets.

mostly all people have this problem & I was worried too about this. But update your phone. you should get a new update notification by now.! I already updated and it fixes this problem. and the smearing issue as well. And then you can also move your apps to sd!!!!!:victory:

Hi, just got my replacement after having some overheating problems and noticed this problem on the new one. I'm pretty sure is the screen, and not a software problem. Mine looks yellowish/greenish on the bottom. I downloaded Screen Test app and notice the problem. I have some pics showing the color differences along the screen. I'll go for another replacement tomorrow.

It's the Tegra smart dimming causing the flickering. Apps like Franco Kernel Updater or Tegra Prism can toggle this on or off. Might be better to manually toggle it by editing a file if you want to avoid paying for an app, but I don't know it to hand.

Smart dimmer is NOT the problem, why do people perpetuate this nonsense... It is some interaction between the wifi and Backlight and is only really visible when wifi signal is low, background is white, and in the dark or near. Meh.

Turn up the backlight a little, I personally don't even notice it much anymore.

I fixed it by lifting the antenna ground with a piece of scotch tape. 7 months and still going strong.
Sent from my Nexus 7 using Tapatalk 2

I had this problem. It was very common around the time the nexus 7 was released.
From what I remember, it's a hardware issue with low WiFi signal interfering with the backlight, as someone above said.
Your options as I recall are to crack it open and attempt fixing yourself, voiding your warranty. Or just send it off. I sent mine off and received a new replacement. It was obviously a common complaint because they didn't even enquire further after I briefly described the problem.
Send it off, save yourself the headache of a hack job gone wrong.
