Screen warm up time - Nexus 7 Q&A, Help & Troubleshooting

When I first load up my nexus 7, the screen looks terribly washed out but eventually becomes normal after a few minutes. In addition, bad screen ghosting occurs and gradually disappears over about a half hour. Anybody else experiencing this? Is this normal ?

I have the same problem :crying:

No, that's not normal... I bought 2 and neither do that. They're just like any other decent LCD device. Instant on without issue. Sounds like you got a dud.

Mine looks the same from the first second on until I turn it off. The only time it "washes out" (Tegra 3 "PRISM" Display stuff) is at very specific times when watching a video (including youtube) or sometimes playing games.
I have yet to see ghosting at all on the N7, I have seen it on previous IPS LCD tablets like my Nook Color, particularly if it decided to get stuck on while charging like it randomly would do. I'd go to another screen and the previous screen, most often the launcher, I'd see the icons for a few seconds on the new screen. But again, haven't seen this on the N7 at all.

I've worked with 5 brand new devices and have never had these symptoms. Not normal

Thanks for your advice. I've contacted Google and am returning this one in exchange for a new one.

I'm on the same boat Mate... :'( ... the problem is, that in UK return process is a real road through hell. I am thinking about accepting it as it is, mere 5 minutes of warmup time, but other than that - flawless.

Random vertical lines?

I've noticed that a random black line sometimes appears on my Nexus 7. It's very brief, probably on a single frame width ways on the screen, not so often, the closest I noticed were about 15 minutes apart, usually much more.
Has anyone else noticed anything like this? Could I have a faulty unit?
Wrong thread mate, q/a or general. I dont have any of these lines though.

I have the dev one from IO, but i don't have that. Sorry man
I have seen that on mine as well. Its almost as if the GPU missed drawing one of the lines on the screen. Pretty rare though.

What ROM are you running? I had this issue on SGT7, but switched to Linaro cookies and cream (motley kernel) and it went away. Smoother rom overall also.

Pretty rare but I've caught a few of those as well. Not so much bothersome as slightly worrying...
The last one appeared while charging but pretty sure I've seen them unplugged too.
Rare, but happened to mine as well. Just hope it won't get worse
same here

I have the same thing. My Nexus otherwise seems flawless.
I got mine direct from google.
Flashing motley's kernel seems to be the fix as of now.

Have you guyz checked if this happens in Bootloader and Recovery ? I did and I could see it there as well which had me worrying. My Unit is just a day old and I was worried if the device was plagued with faulty screen.
I saw this behaviour for atleast 6 hours and now it has disappeared ! I've seen these crap happening to LCD TVs as well, usually temp in the beginning but eventually it pops up forever !
Thoughts ?
i'm experiencing the same. but horizonal. but i know its a software thing..will be patched up soon.

Nexus 7 3G Defects - here!

Hello people!
As we all know the nexus 7 32gb 3G has shipped!, This is for everyone who has the Nexus 7 -3G- version only!
Do you have an issue with anything of your nexus 7 components (screen issues - build issues - speaker, etc ...) that are found on the previous builds of the nexus 7 non 3G ?
Did you guys find something that you like or you feel is better than the one with the previous build or non 3G (if you own a non 3G nexus)
like say, Faster, snppier, better graphics, performance etc ..
Sorry for my not so bad English
Just had 2 3Gs arrive to replace my old 16Gb wifis
Both perfect in every way, (Saying that so were my wifis)
Only comment is (Are google trying to get apple to sue them over the sim removal tool!!!)

Oh the reason Google are stating that Cases for the wifi nexus 7 are not compatible with the 3G version is that the Mic has moved due to the microsim slot so the flap on the cases covers trhe mic on the 3G version.

This seems a little pessimistic to me. Why assume they are going to have tons of defects? Won't google/asus have learned from the mistakes they made with the early wifis?
I didn't mean to be pessimistic at all .. just scared of that feeling when you wait so badly for that shiny device that you ever wanted but only to figure out that you have to sooooo lucky to get a (well-made) one without any defect !! I hate QC.
i see the need for this very much,
i just got the 32gb wifi only and maaaann.... the feel to the tab is just...different like the back panel feels...better i cant really explain it the unit feels heavier too.
Got mine this-morning. No defects at all. Why would you expect any? The Wifi version has been out for ages so any major defects would have been caught long ago by the early adopters.
The only "defect" per-se is deciding what the best deal on a SIM card is... 3 is probably the best network... but what one to order? All rather confusing for a poor old mouse brain.

I got mine last night. It has some backlight bleeding and also has these funky faded streaks (hard to explain) on a black screen these streaks give the blacks a washed out appearance. I compared it to my 16GB N7 which I got in Aug and I didn't notice these streaks but do have backlight bleeding on that one. I'm actually getting it replaced for these streaks but I've come to expect and even accept(as long as it's not horrible) backlight bleeding on Asus tablets. Having owned the TF101 (3 of them) the TF201(3 of them) and the infinity I have not came across a single one that didn't have some backlight bleeding to an extent or another. Some having it much worse while others maybe having just a small spot in the corner. But I honestly have not seen a single one (mine or a friend's) that didn't have backlight bleeding to some extent.
Mine has some very slight backlight bleeding, but nothing I'd complain about. Unfortunately, it does have the blown speaker issue...so an RMA replacement is on its way.
I bought a 2nd Nexus 7 3G version and all the issue of my 16gb WiFi are gone... The main problem the light flickering which is gone totally, also the screen is now flat with the bezel finally.
Sent from my Nexus 7 3G
Mine is fine overall. There seems to be some slight backlight bleeding on the left side of the screen, but not major enough to RMA.
Speaker sounds fine too as far as I can tell. The only "issue" I think I can report is that when my tablet has been sleeping for a long time, the mobile data will cut itself back on if it's off. At least the mobile data works though. Anyone else experience this?

I forgot to mention that I have noticed my screen flickering a bit when in 'auto', and depending on the ambient light. It's almost like the screen can't decide where to set itself and is bouncing between 'levels'. The problem seems to go away completely when I just turn off the auto lighting and keep it at minumum (which is how I usually use it). Is this the screen flickering problem everyone keeps talking about?

Just got my replacement an hour ago. Body creaks less, bezel appears slightly more even (although the old one was really even to begin with), and speaker sounds MUCH better. Only slight buzzing from the 'notification' volume bar, default tone, at max. Everything else sounds clear. I'll have to watch the screen to see about flicker. I have noticed it switching levels, but haven't noticed it flicker yet. It also appears to have less light bleeding. So far so good...
Ok guys - I need an opinion. I've had some time to play with my replacement N7, and noticed some odd things. I ran the battery down last night just to make sure it wasn't a dud - got about 10hrs of video (minimum brightness, sound down). It's not as good as my first one, but I don't consider it a dud. However, after it died, I plugged it in. A half hour later, I tried to power it on to collect the batter logs (simple battery logger), and it wouldn't power on. I pressed the power button for 5 sec each time, nothing. No white battery charging logo either...just unresponsive. I kept trying and it finally booted. I think I had to hold the button for 10-15 sec - and the battery was charging and at 10%. Never happened like that with my old one - just a consistent 4 second press to power on. Does this thing need 10% before it will power on? Reading the forums, the power on issue seems to be common. Should I be worried about this? Should I just keep my original unit even though the speakers are bad? I really don't want to end up in the endless replacement loop. Do others here have occasional power up glitches?

Nexus 4 screen distorted/tearing

My wife just got the Nexus 4 the other day and she has problems with a potion of the screen becoming distorted very often. She said it usually happens at least once everytime she is using it. It's with no particular program or doing a certain thing, just random. The phone is stock still. I attatched a picture and you can see at the bottom of the screen. It's not always the bottom, sometimes it's at the top, sometimes bottom. She said it hasn't happened in the middle of the screen (yet). Has this happened to anyone else and does anyone have any ideas on how to fix it?
Don't try to fix. Get it replaced.

I had the same problem, but my phone was distorted all over. I returned the original phone they sent me. When I got the new replacement phone after just a few days it acted up the same problem. I returned it to Google and never purchase the Nexus 4 again. I'm glad they gave ma a full refund minus the shipping though. Right now I'm still searching for a good reasonably price phone
Just return it and ask for full refund before your warranty runs out.

Moto X Screen burn-in

I bought my Moto X around the end of September and about two weeks after getting it, I had a screen burn-in from the notification bar and navigation bar. I let Motorola know and they happily replaced it. However few weeks after owning the second one I experienced the issue again and I let them know. They told me they were stunned and that I was literally the only person who had reported the issue.
What I am wondering is if anyone else has experienced this. I know it is a common problem with AMOLEDs, but I didn't expect it to happen so soon.

I have never seen screen burn in on any phone. Not sure I would notice it in the notification and navigation areas since they always display the same things.

I saw burn in on a display model at Best Buy. It was the big Motorola M logo that displays at the boot animation. If you looked at a white web page or any solid, but light colored image, you could see the ghostly circle the size of a quarter complete with the swishy M in the middle of the screen. Got them to open a second demo model and boot it up so I could see a clean screen and bring it to their attention. Weird thing to have burned in, too.

Op did you leave both phones display on for 2weeks straight at 100% brightness? Lol
I have had mine for 2 months, do at least 4 hours sot daily, most of which is on reddit and xda, so nav and status are almost always static... I have zero sign of burn in.
I had it pretty good on my s3, but I blame ingress for that... Being outside playing so much and had it at 100% brightness because that screen was so dark... Even then it took at least 2 months before I saw any burn in and I was playing A LOT!
Can't imagine how you would get burn in on two devices, each in two weeks... Seems like that's a feat that you have to try and do, lol.

I'd be hard pressed to believe this as well... I've had numerous amoled devices and abused the crap out of them and even then, it took months to get any sort it noticeable burn in... If it were one device then I wouldn't second guess it, chalk it up to manufacture defect... But two in a row? I'm curious as to what the op uses his phones for and if he ever turns off the screens... Even store display models take a while to get burn in and they are on 3-4 times as much as a typical power user.

I'll have to send you a pic of my GNex then, so you can see the perfect "ghost" of a Pandora logo in the middle of the screen from running the display full time in my car dock.
I also remember similar complaints when the GNex first came out, of people claiming they were getting burn-in on the notification bar area, and I thought they were ridiculous at the time. Now, not so much.
It happened to my gnex, so I'm not surprised that it happened on this phone too.
I'm not saying you're faking it, but 2 weeks is a little too soon for it to be happening. The gnex only had the issue after a year or so. Are you keeping the display on all the time when charging or something?
They will eventually burn in if you set the screen to never time out and leave it displaying the same thing for hours or days on end. Most store models have some level of burn it. In normal use cases it should never be an issue though.

Just passing by, but 2 weeks is entirely possible.
If you keep using the phone with the notification bar displayed and then two weeks later open a full screen browser, you will most likely notice burn in if you look close enough.
It's extremely easy to do.
I bought an S3 from ebay with real bad screen burn in (that the seller didn't mention). She actually didn't believe me and accused me of scamming her until I replied back with a contact name and number that was burned into the top of the screen from the messaging app (the keyboard was also burned in, I guess she constantly texted this person).
I think burn in is more likely to happen when brightness is higher. I had a GNex and GS3 that never got any sort of burn in but I also rarely had the brightness above 50%.
you know, now that I look, I have it too. It's faint, and I thought it was from the Nova Launcher beta, but ****, this is screen burn in. Damn.
---------- Post added at 05:26 PM ---------- Previous post was at 05:13 PM ----------
I don't even use my phone that much. Generally around 1.5 or 2 hours screen time per day. Brightness is about half. Kinda crazy.
Recommend using an app such as:
https://play.google.com/store/apps/details?id=com.feetstech.screenburn&hl=en
to minimize this. Most plasma TV's have something like this built in as they are also prone to burn-in. Use it for 10 minutes every once in a while (even if you don't see burn in) and it should prevent it.
I got screen burn in on my S4 after 2 months. But I also blame ingress for that. I have a X coming and hope to minimize that by not playing ingress so much or play on another device. One thing that I do for the status bar to help out is with nova launcher I have it set to swipe the notification bar on top away. I try to leave it off the screen as much as possible. But yes amoled screens suck for burn in.
I usually turn my phone to the 270 degree position to have the navigation bars switch sides every now and then. That helps a bit.
And with AMOLEDs, it's more important to turn off the screen when not in use rather than let it time out. I have mine set to 10 minutes, but I usually manually turn off the screen because I know AMOLEDs are prone to burn-in over time.

[Q] Nexus 4 touchscreen and Battery Issues

Hellllo everyone!
I bought a Brand New Nexus 4 a 5 months back from an unofficial distributor. In the Beginning I loved the phone, but now this phone is really giving me a lot of headaches lately.
My first issue is the Ghost touch and dead zone issue that has been affecting quite a few G4's lately. (Since I enabled "Show Touches" in developers options,I am able to see any touch inputs on my phone. )
The ghost touches occur right in the middle of the screen (Right where the dead zone is) and the ghost touch issue disappears when I lock and unlock the screen.
The ghost touches may show up again after a minute, 10 minutes or maybe even the next day.
To my dismay, I think that a new dead zone has appeared (however, much smaller than the dead zone in the middle) a centimeter above my Navigation bar.
My other issue is that when my battery reaches a certain level, say around 25-38%, the whole screen erupts in a fury of touches all over the screen. My phone is rendered unusable, until I charge up the phone.
And another issue is that when I restart my phone, the touch screen sometimes does not respond at first. It then starts working after a while. It could start working in 1 minute or it could start working in an hour. This particular issue only happens when I restart the phone
Honestly, I have taken care of my phone, and never dropped it or abused it in anyway.
I read reviews about the whole "Amazing Quality" of the Nexus 4, and was bought on looks and design of the phone, but right now I'm really starting to regret my choice, and wish I went with an Xperia Instead.
Sadly, since there is no official LG or Google Service centers where I live, and since I bought this phone from an non-official shop, I'm unable to send it in for warranty claims.
I'm quite adept in opening up electronics, so I have no issues opening up my Nexus.
Does anyone know of a way to fix this phone, without a Digitizer replacement?
And is there anyone out there facing the same problems?
You still have lg warranty regardless of where you bought it from. Its more likely that you got a refurb though. In terms of fixing it I think you are in for a new screen.
Hey, thanks for your reply
There is no official warranty where I live, so I cant RMA it to google or LG.
Honestly through the issues keeps on increasing day by day.
Now it looks like my battery dies around the 60% mark. I guess my battery is uncalibrated?
Anyways, now because of these battery issues, I cant make it past 4 hours of use before the touch screens acts up and the phone shuts down.
I am very unhappy about this phone.
Any way to solve the battery issues?

I found out that this issue is most likely due to the battery. It somehow became slightly inflated, thus severely reducing the battery life and throwing off Android's Battery meter.
I tried over 6 different touchscreens and they all had this problem.
Great, I now have to buy a new battery as well.
And another issue is that when I restart my phone, the touch screen sometimes does not respond at first. It then starts working after a while. It could start working in 1 minute or it could start working in an hour. This particular issue only happens when I restart the phone

A full factory reset of the phone, helped to solve this particular issue.

The ghost touches may show up again after a minute, 10 minutes or maybe even the next day.

And there is no fix for this other than a full Touch+Display Panel replacement.
Right now I'm going to have to buy a cheap 10 dollar phone as my main phone, while I raise up the money and find the time needed to search for and buy these parts for my Nexus.
Honestly, Google and LG have made a very bad impression on me, and I will think twice before buying another LG Nexus phone in the future.
Update:
I Bought a new Display and a new LG Battery, and so far all my issues have been solved.
Now I guess I have to sell this off.
meh.

Sorry for the very late reply, but yes, It does seem that you will have to replace both.
