Random Black Screen Flashes - Nexus 7 (2013) General

I have owned a Nexus 7 2nd gen for a couple months now and have just started to get random flashes of black (occurs for not even a quarter second) ...
I am wondering what causes this...
I have not damaged the Nexus in any way and bought it brand new..
I have only used CleanRom and PA ROM...
The functionality of the tablet remains great, but the flashes are very annoying ...I have tried clean installing multiple times but the flashes still happen...
Any feedback/solutions would be a big help...
Thanks

The whole screen?
I've noticed black lines when playing Terraria for hours but its only the background of certains areas. I chalked I up as game glitches.
I haven't seen anything outside of that.
Give us some more details.

I had that happen soon enough for a return to be viable. Do some more Google searching and you'll find people who fixed this as a hardware issue. They had to open the back and fiddle a connection. Didn't sound to hard but I just went to best buy instead.
Happy hunting, sorry I don't have a link.

Yea I would exchange it before it is too late. Doesn't seem that troublesome but if it got worse, or worst, disconnected entirely, it would bring bad news.

What specific piece of hardware is causing this?
I still have this issue from time to time ..
I've notices it happens a lot less if I turn off auto brightness and manually turn brightness above 45-50 percent...

Just because you bought it off ebay doesn't mean it doesn't still carry the 1 year manufacturer warranty on the hardware. It would require you to send it in, but worth a shot.
Once you pop the back and start fiddling with hardware, you run the risk of doing enough damage where Asus will void the warranty. I think I would check with Asus first before resorting to hardware modifications.

I should send it in to Asus you say?
What are the requirements to have it repaired/replaced under warranty as I have already rooted it with a custom rom

So... is this the flicker problem

Sometimes while watching the screen, every now and then I get a flicker, I only noticed it when I was staring at the screen reading a book, if so I am sad because my OTG cable just arrived and I was having so much fun
Your life is ruined.:thumbdown:
Sent from my Galaxy Nexus using Tapatalk 2
well... at least it works and theres no other horrible problems so I can still play with it until google send me a new unit :silly:
Reckon I should wait a few months so I guarentee a unit from the new batch, or just do it now?
You know what. As I was reading your post I started to see tons of flickering. Thanks a lot. Lol jk. Better now than later. I'm still in my 15 day window
I'm stuck dealing with Asus.
I'm leaving the country for a 3 week vacay so I can't deal with a 4th exchange from Google Play.

I think it's worth a shot. My replacement is perfect, much like many of the initial batch / recipients. Risk you take, right?, jumping on that first wave. Seems like things have settle down, think the negative outcry is just more easily heard thAn the positive.

Definitely going ahead and do an exchange now. Got my replacement unit today and this one doesn't have a flicker problem at all. My last one had really bad flicker.

Well I only got it last week so that makes it better if I submit that its faulty at this point..
might seem like a stupid question, but where the hell do I go to organize a replacement
I've seen the flicker on mine and called to replace it. I was told to try a factory reset to see if it was hardware or software. I said I'd try tomorrow and call back/set up replacement if it doesn't work. What do guys think? Could it be software?

You're either crazy or have a defective unit. As with all Nexus devices, the response time and software is great on the N7.

What I find amusing is that you have made 6 posts about the Nexus 7, the first being July 20th.
A couple about trying to use VPN with pptpd, 3 about keyboards, and 1 about how to spend your free $25 Google Play dollars you got when you purchased the Nexus 7.
NONE about slowness or anything related to your OP here.
In March you had this gem to say...
Anyone else hesitant to order after rumors of Google $150/$200 Tablet?

Response time? Are you serious? Are we talking about the Nexus 7? By the way anything you get that isn't a nexus 7 is a downgrade, Best tablet ever. I'm going to be with this for a very long time.
Sent from my Nexus 7 using Tapatalk 2
Well I'd really rather keep it. Even typing this I'm having to hit keys multiple times. Very annoying.
No one else having these issues at all?
Perhaps I have a dud? Anyone know how difficult it is to get a replacement from Google?
No issues here, using swiftkey.

I most likely will stay with the N7, but *IF* I were to trade this in, I would most likely get the Galaxy Note tablet soon to be released. For me, having a fine-tip pressure sensitive stylus would be awesome. However, after having so many tablets, I think the 7" form factor is the perfect size. Now if Samsung comes out with a Note 7...I would be hard pressed to stay with the N7.

Right I thought I was having keyboard problems which is why I tried 3-4 different ones and hated a few. (krelvinaz knows what I'm taking about since he keeps tabs on my posts). Now I believe I wasn't actually having problems with swiftkey 3 or swype but that I'm getting flakey touch responses. Currently have Thumbs installed and still have to hit the letters a couple of times for them to register. Just went back to the stock keyboard and same thing is happening. I have to key really slow to make sure every letter touch activates.
Here's another odd thing, I just installed the app Multi Tough Visual Test so see if indead I was having problems with my touch screen and every click and gesture I do, even with multiple touches all register. I even tapped super fast and still I see everything showing up. So this leads me to believing the hardwares fine.
I do have it rooted, perhaps if I have time I'll do a backup and factory reset and/or try a custom ROM.
I'd simply warranty the thing out. Your problems are clearly not typical of the nexus 7 experience.
Well I did a factory reset and response times are better. I can actually type now. Using SwiftKey keyboard for a try.
Only installed keyboards and titanium backup. I'll slowly start adding back my apps.

+1. I'm having the same touchscreen issues with mine, going to call up Google for an exchange tomorrow.
I'm not having the lag issue when I type, but I get it pretty badly when scrolling around Chrome and various other apps. Early the lag was so bad that I turned it off for a few minutes, then when I booted it back up, there was a red outline surrounding the entire screen for about a minute, then went back to normal. I'm just going to return it tomorrow.

Screen bleed. RMA?

Ive recieved RMA today, device is nearly perfect. The only issue is the screen bleed. ive attached one screenie with auto bright and other at max.
Do you guys have the same? Can you post here?

Ouch, that looks horrible. I would have definitely RMA'd that as well myself. Mine is also "nearly perfect" and has two very small areas of backlight bleed but nowhere near as dramatic as yours and I don't think that I'll be RMA-ing mine for that alone.

Pretty much normal for LCD displays, you can always get screen bleed to appear when viewing in the dark and at high/full brightness, it is a limitation of the technology. When you have it on auto or sensible brightness and use the phone normally can you notice it? If the answer is no, don't worry about it.

I can see it ocasionaly. For example, when I started up I saw google logo and could see it perfectly...

Yes unless you wait for the charges from the first rma to drop off.

I wouldnt be surprised if the RMA was returned because of screen bleed and then they sent it to you and hoped you wouldnt notice. Every RMA is probably an old return since they dont even have new ones to sell.
Did you get the RMA right away or did you have to wait awhile? If it was right away then it must be a faulty return.
It took 5 days. Now that you say this.. Phone had some dirt and had finguerprints tho "i was the first one to open it"

I bought three Nexii on November 27th and all three had screen bleed. I can't see OP's pictures to compare but each phone has a ~1/4" area of bleed with one phone having two. This has only been visible when playing a movie and a black screen is shown at the beginning. I don't notice it at boot up, for instance.
I don't know if this bothers me enough to RMA yet. My thinking is to punt the issue into next year, wait for supply to catch up with demand, and then RMA for a new unit. Two of my Nexii are going to relatives so unless they notice it, I don't think I'll bother RMAing them.
I remember seeing someone mention in a thread that LG can't seal an LCD to save their skins and that person is knowledgeable, in retrospect. The issue looks exactly like some adhesive wasn't applied or pressed down evenly during assembly. I wouldn't be surprised if assembly by hand is the cause of the problem, due to expediency in order to fulfill existing orders.

You cannot seriously believe they do this? They have separate batches for new sales and RMA.
I agree with everything u said. Mine has 3 bleeds 2 on top and one on the top left. Im not going to RMA my N4 though its a non win either way so many people get stuck in a RMA cycle. If your phones are good other than light bleeds ID stick with them. But that's your call good luck with everything.

You have one year for manufacturer defects. Please hold off at least a few more weeks on RMA so people whose devices develop issues that seriously affect functionality can get a replacement quickly.

My guess is that it's common practice. I know I've RMA'd devices to other manufacturers and gotten back "refurbished" devices. I'd be surprised if the refurbish process is any more complicated than booting it and looking for cracks in the glass.
A certain percentage of all electronics will be returned. A subset of those are perfectly functional devices. This is a function of having variable intelligence in the population. Now, rather than spend resources to determine which exactly of those returns are actually pristine devices that the mouthbreathers couldn't decipher, if the percentage in a sample is high enough, the company might well choose to mail out any that aren't obviously damaged and take the chance that the device will satisfy the customer. If it doesn't, they can always mail another.
Hiring a worker to mail things is a lot cheaper than hiring and training a worker to diagnose complex devices. It's also much slower, which means more labor costs. Even if they have to mail a device twice, it still comes out cheaper and faster than diagnosing every single return.

Between a rock and a hard place...

Hello all,
I need some advice concerning my Nex4. As many people have experienced, I also have a slightly buzzing earpiece and now I'm in doubt whether to use my warranty and get a new one or not.
Since I live in Holland I got my Nex4 through someone else from a store in Germany, about 1 - 1,5 hours away to reach it if I want a new one. Since I'm 15 and not able to get there myself I'll probably will need to go through some quarreling with my parents to get them to driving me there.
The issue is that I'm not sure if I want to go through all those things, since the problem doesn't actually bother me. I can make good quality calls with a little of buzzing which I don't mind and I'm happy with my battery life: 3-4 hours of screen time on 1,5 days with medium usage.
I hope you can give me some counsel. Thanks in advance!
By the way, when I'm studying in silence I sometimes seem to be able to actually hear some high-pitched sounds, which I do mind, but I guess that's partially a placebo effect.

I just got a REV 11 device. it still makes the nose, albeit slightly quieter. With that said, these phones have build quality issues and getting a new one might be more hassle than it's worth. My REV 11 device has a slightly worse screen than my REV10 (lots of streaks on the the grey scale). Just keep that in mind.
Wait, REV 10 and 11? Did you already do this many RMAs or did I misunderstood the meaning of the word ^^?
Sent from my beloved Nexus 4
You misunderstand the word, REV is for hardware revision, a new revision comes with small changes. I got a REV 11 device and it's my first one.
Also keep in mind, you don't know if your replacement device is going to be any better.
Ah, thanks, any idea if I could check my REV?

There is no danger in booting into fastboot made & checking the info. IIRC with the phone off hold volue down & power at the same time.

Brand new nexus 4 blank screen

Hi
2 days ago i bought a nexus 4, i unboxed it very carefully and turned it on, but there was no any Google or Nexus logo, at first i thought its normal but after 10 minutes i turned it off and on again, but same thing happened, after about 1 hour of trying, google logo showed up and i was able to work with it but with some problems, for example camera didn't work, then i updated it from 4.2.2 to 4.3 and it worked normal and i was able to use camera.
after 2 or 3 hours same thing happened again and now its 1.5 days that I am trying on and off options.
i held power key for 10, 15, 20,30 seconds like million times but nothing happens and every time i see blank white and gray screen.
unfortunately I am in a country that google doesn't support, for love of god please someone help me to make this thing work, i waited to long for this phone and i love its look and feel.
thank you all.

Before returning it try using one of the tool kit and flash stock image. It could be an issue with software. Won't hurt to try.
