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!

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.

I can attest that the flicker is ever present in a pitch black room as well.

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.

hey,
I've noticed some lines showing up on my screen... they only show once every 10/15 min and run across the vritical when in landscape mode. typically only one or two pixels thick and lasts only a moment.
Like every one my tablet takes a tumble now and again, but if it was hardware then my is it so intermittent?
any ideas?
I think this has happened to mine too but it flashes so fast that I don't know if it's happening or I'm seeing things. It's very rare though for me.

I get it every now and again, seems to happen when the screen has been on for a long period.
Not sure what is causing it, I tried to Google it but couldn't find anything.
It seems to be software guys, as before the 4.1.2 update I was getting these lines around 2x as often. Hopefully the next ota knocks them out for good.
I think it is WiFi reception strength related. In my case, they appear only when WiFi signal is weak. They have been there since the beginning. But now, not only vertical, some times horizontal lines appear as well. Horizontal lines didn't exist before 4.1.2 update. Same issue have I with my TF700. So, I assume it's both hardware/software related.

I never had this with stock rom but have had it with some custom roms, I had it with "slimbean 2.7" but since updating to 2.8 it has gone. So, it points to software.
Maybe megamoz is onto something too.
I don't think it is a faulty screen. Something else is going on.
I am on rooted stock, had them both before and after rooting.
Don't think it is related to the WIFI, not for me anyway, as I get it when browsing in the living room and I sit right next to my router so I get full signal.

that would sound like a prime candidate for me. I have been stuck in hospital for 10 days, and the tab has been on for 15+ hours at a time some days... although the wifi angle is interesting too.
just happy its "normal" and not that I dropped it
thanks everyone for you input
Yeah I am also getting them and they seem to happen more when there is alot of white background on my screen or maybe that's when I notice them more lol but as far as problems go that's all my NEXUS7 has so hopefully it is software and can be fixed with a good old update COME ONNN 4.2 GOD BLESS YOU GUYS

Same here. I sent it back. Ordered a new one a couple of weeks later from another place, same issue.
There are many articles and threads about this problem, but unfortunately Google and ASUS seem to ignore it. And even here on xda, people get defensive about their Nexus 7 and downplays the problem, attacks DisplayMate for scientifically illustrating the problem etc.
It annoys the hell out of me because I _want_ to love the Nexus 7, I _want_ to _want_ to keep it. It has great hardware, great software and even the IPS screen is great, but unfortunately the end result is a display that is seriously miscalibrated. The simplest calibration tests of black level, shadow detail, white crush and saturation and intensity (especially of the green primary) shows the major issues. Worst, it is obvious in daily use all the time.
I probably will end up sending this second Nexus 7 back as well and buy something with a half-decent visual experience.

I already have PRISM disabled. It helps a tiny bit but does not begin to solve the problem at all. Gamma, white crush, green saturation and intensity, contrast etc. still looks like something from 5+ years ago.
And there are a billion threads about this on the internet. I wish Google would take it serious, but...

Is anyone else having a slight misalignment on the touch screen?
For me touch is shifted about a millimeter or two to the right.
I've checked on both my N4 and my sister's N4 and both of us seem to be having this slight misalignment.
Both of us have REV 11 N4's. One was obtained through T-Mobile in January, the other was obtained through Google Play just last month.
I've checked on a few roms. I've tried CM, PA, and Stock with a multitude of different kernels (Franco, Faux, Trinity, CM, and stock).
To check:
1. Enable "Show touches" under the Developer menu.
2. Touch a part of the screen where you'll be able to see the touch bubble and hold it there.
3. Look at the screen at angle to see under your finger.
It's not a big deal, just something I've noticed when I had difficulty trying to use PIE on the left side of the screen. Although, I still would love to be able to get the screen recalibrated to have more accurate touch sensitivity to eliminate the difficulty that I have with CM's PIE.
Another question: Is anyone aware of any LG diagnostic tool to calibrate the screen? I remember back on the HTC sensation there was a file that you could load through HBOOT and get your screen calibrated from there.
Photo attached.

I thought I was just trippin when I noticed the same thing last week
Just tested and confirmed, pretty significant misalignment by about 1 cm, which is a LOT when you're talking about a <5" touch screen..
My next thought is, is this a software issue?
We need more people to test and confirm. But I believe that is what we will find. Software issue.
Anyone with a Nexus 7 on stock 4.2.2, please also test and report.
Wow never thought anyone else was experiencing this, mine seems to be off since I always have to touch a little higher than what I'm going for even nav bar.

I would think that it's a software issue. My HTC sensation was able to have it's screen recalibrated. I think LG would have some kind of tool to be able to do 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

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.

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.

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.

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...
