Nexus 7 screen flickers on low brightness becoz i use the device at lowest possible brightness to save battery but screen flickers while using wifi specially on webpages having white background

this issue has already been discussed, a simple search and you would've found the solution. Just turn off wi-fi optimization and no more flicker

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.

You could also download trickster mod and set it with that. Has paid and free versions.

Are you using the Oxydo kernel? That makes my screen flicker too, try using m-kernel

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.

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.

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.

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.

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.

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?

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.

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.

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

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.
I usually keep my phones on full brightness. I'll deal with the battery draining because I love how it looks with full brightness. Has anyone noticed the display on the n4 kind of adjusting sometimes. I have noticed sometimes it changes to a little darker or a little brighter while using the phone.
I also noticed when I am talking on the phone with the speaker on sometimes it shuts when opening an application or sometimes even without opening an app and switches to regular ear piece. Sometimes it will stay on speaker but go lower.
Anyone having these issues? Its not a deal breaker or anything I still love it. I know phones will always have their issues, I've had ever nexus and the g1. I just want to know if other people are having this issue.

It's adaptive contrast, runs independent of your brightness settings and there's not an option to disable it. You probably notice it most when moving from a largely black screen to a white one.
I think I remember first hearing about it's use in a Galaxy S2 review, my TV does the same thing on its dynamic setting.
