Phantom touchs

I've been dealing with a phantom touch issue with my shift. Pefectly centered in on the botto of the screen where it hits the phone button in sense. Its looking like a hardware issue.
My question is, has anybody else experienced this and has anybody dealt with taking a rooted phone back to sprint for service?
Thoughts?

I had a weird issue where an area (the left side of the screen 2mm strip) on the touchscreen didn't work at all. I used the one zip RUU back to stock and brought it in and they gave me a new slider (whole top portion). Just happened 2 weeks ago.

I have bad problems with that and screen protectors, especially when it's really hot and humid (like everyday here in tampa)

At first I thought it was the screen protector, but the problem persisted after I stopped using them. And then I thought it was a bad rom or rom install, so I tried 3 different ones with no change. So ill just update myself to the OTA GB and take it in for service.

Did the rooted update to GB and it seems to have gotten rid of the phantom touch issue. I ended up having to do a factory reset when I did it, so maybe that helped. Glad I don't have to deal with customer support now. There always seems to be a line when I go in.

Just want to say you're not alone, this happened once temporarily on my G2. It made pressing the "s" and "a" keys on the on-screen keyboard almost impossible!

Screen tearing fix?

I remember reading a few days back about people having issues with screen tearing. My screen will display a symptom where it has a jagged line shoot across the center area of the screen real fast and then go away. I was wondering if anyone found a solution to that?

No progress has been made, yet. Some think it will be fixed in a software update. When I notified Google support of the issue, they thought it was a hardware problem, but if several people have the issue, maybe it's software.

I'm hoping it is fixed in a software update. That is literally the only issue I have with the tablet.

Yeah I hope so too, but I already have a replacement on the way. I have some other issues with mine though that I felt warranted getting a replacement.
Does the tearing happen to you all the time or just in certain apps? It only happens on mine when I'm playing music. It will show up for a split second as a quick horizontal line then disappear. The line appears in different areas of the screen each time. I notice it the most when it happens in Chrome, but I've seen it on the homescreen and in other apps as well.

Mine happens frequently throughout the ui. Xda app, chrome, everywhere really. If it is a software issue though there really is no point in exchanging. It seems to happen more frequently in an app with a light background.

I have this problem as well.. I only notice it in tapatalk though.. I'm not sure If its because I use tapatalk all the time or what..

Mine happens in chrome pretty regularly as well. Could it be something with the video drivers for this thing?

So apparently it was a bad kernel that I was using that caused the problems. Flashed a completely stock build and the problems are gone. To the people that chimed in and said they had the issue, are you on a stock ROM or did you change that and the kernel?
Sent from my Nexus 7 using xda premium

I've noticed this, but it's only happened twice (so far), Once was whilst using chrome, the other time just sat on the homescreen. I'm currently using stock.
(Not too worried, just as long as it's not a line of pixels about to give up the ghost as some other people have had).

Happens to me on stock rom. My N7 is not rooted or unlocked.

Pretty sure this only happens when you force GPU acceleration. I had the same issue, turned it off, and never saw it again.
Of course I love GPU acceleration too much to leave it off, but a jagged line every once in a while is not a deal-breaker for me.

Glad it worked for you, but I don't have that option on nor any other's enabled in the development menu. Regardless, the issue persists.

Is there anyone else having this issue?
I received a replacement today, but I couldn't escape defects on that on that one either. I'm trying to figure out if I should hang in there for a fix on the screen tearing/horizontal line issue, or if I should just send both back and call it a day.
Sent from my Nexus 7 using xda app-developers app

I just found this thread. I have the same issue. I'm on stock kernel, unlocked/rooted, and stock rom. I don't have GPU acceleration forced.
Any further ideas? Could be a driver issue.

People here think the screen flickering issue could be resolved in software, but I'm not sure about the issue we are having.
I might go through the unlocking process just to see if the horizontal line stuff happens on other roms/kernels.
I really hope it can be addressed in a software update. I just struck out on my 3rd nexus. All of them have screen defects. All have had other issues like creaking and slight screen lift, but those are a lot less of a problem to me. The original one is ok except for the horizontal line issue. My two replacements each have dead pixels and dust in central areas of the screen.
This is ending up to be a very tiring and disappointing pursuit.

If it's a software problem it's likely to be in the tegra3 proprietary driver blobs. If this is indeed the case, changing rom and/or kernel will make little difference (because they share the same blobs).
It might be possible to work around the issue outside of the blobs but its likely only nvidia can fix the root cause.

Hopefully someone at Google watches some of these threads. I have 2 nexus 7s with this issue. Thanks for trying to save me the time of trying a different ROM/kernel, but I might still try a CM10 build for kicks.

My first tablet had one dead pixel and it had this issue too. My second one is perfect except for this problem. It probably does have to do with the tegra 3. I hope its a software issue because this one is perfect except for that one problem. I'm not rooted nor unlocked and no force GPU rendering either. It only occurs on some apps with mine. Tapatalk, facebook and barely ever on chrome. I haven't seen it on any games or video nor on the home screen. There should be a place to report this to Google... I doubt they are searching through xda looking for every little problem. I've had this issue for a while and have been searching specifically for bit and just found it today. Also I never see it in horizontal mode.
Sent from my Nexus 7 using Tapatalk 2

I have this issue too and I think it's likely to be a driver issue as it appearance seems random and sporadic in frequency, but it's always really hard to tell about these things.
In any I'm guessing some people just don't notice this issue and thus haven't really talked about it. But it sure is discomforting seeing it.

I seem to suffer from this too.. Everything is stock on mine, no mods, no flashes no unlocks.. It appears to be worse when its been on for a long time.. Wondering if its heat related?

Weird graphics corruption.

Hi. I have had this Nexus 4 for about a month and it has does some strange things with the graphics on the bottom bar of buttons. Please see the screenshots attached. It can happen every few minutes and as soon as I touch the screen it will revert to normal again.
Is this something that is likely to get fixed with an update or a hardware issue?
I can't find anything on the internet referring to the same problem but the sales guy in the local carphone warehouse has a nexus 4 as well and said his does the same :-/
Anybody know what is causing it.
Completely stock BTW oh and as you can see. Pressing the hardware buttons for a screenshot does not fix it. Only touching the screen.
Sent from my Nexus 4 using xda app-developers app

Wow.. thats not normal! I would look into RMA'ing that sucker!

You could try using a toolkit to reflash stock to see if that helps, however you will have to unlock the bootloader, flash stock rom and then relock bootloader, then you just go into settings and do a full reset to hide the developer options then you will be stock. The toolkit I use is this one http://forum.xda-developers.com/showthread.php?t=2015469 and its awesome just follow the on screen prompts.

I'm quite sure that this is a software issue, since hardware issues can't be captured by screenshots obviously. I'd recommend flashing it with whatever you like and do a factory reset. You can restore all apps afterwards ofc (use Titanium Backup for example).
Best regards!

That only means that it isn't an issue with the physical screen. It could still be an issue with the GPU or other hardware, since various hardware is used to create that software image in the first place.
I have seen exactly this sort of picture posted in at least one thread before on here before, though that might be hard to find on a search.
I would also recommend reinstalling the ROM and if it still happens then it must be hardware. I strongly suspect that it is the hardware.
Sent from my Nexus 4

Thanks for all the replies
I have now disabled HW overlays and it does seem to have fixed the issue (or at least made it far better, I have not noticed it since but it has only been an hour)
I will keep in eye on it for a bit and if it lasts cone back and change the title of the thread to solved.
Thanks for all the help guys.

hmmm, and the gpu just decides to screw up down there in a perfectly aligned rectangular shape that happens to resemble the navigationbar? i think thats unlikely.
gimpor, can you play gpu accelerated games? try please.
its probably googles weird 4 layer stuff. thats why disabling hw overlays fixes it. same guy that screwed up the kernel colors that merged it into 4.2.2 btw. : P
gimpor again,
hwoverlay is not permanent, a reboot unchecks it. try this
replace persist.hwc.mdpcomp.enable=true
with debug.mdpcomp.maxlayer=3
in your build.prop
or in the worst case persist.hwc.mdpcomp.enable=false

Its much better but still not fixed. Only done it once in about 8 hours whilst playing a solitaire game. I will try the other suggestions when I have decoded them into English :-/
I have not found any games that don't work yet, bad piggies etc. Seem to work okay. Would they be GPU accelerated?
Once again thanks for the assistance with this, it does get rather annoying when you show someone your phone and it's all garbled.
It still does this though :-/

Ya it was happening on stock as well for me too but I thought it was only my SMS I see you say others are having the same problem... Did you find out if it was hardware or software??? Have you done anything at all or is it still screwed???
Sent from my Nexus 4 using xda premium

I haven't found out anything further and it's still doing it but not as bad. It doesn't seem to happen to every stock phone so I'm guessing its hardware related, or at least something in software not playing well with this specific hardware. Mine is a 212 so they may have changed something on the later ones. I got it from Carphone warehouse on the UK as they were the only ones with stock. I had it changed already as the first one I got was DOA. I think it's going to have to go back if I can't get it fixed soon.

Occasional home button response delay
Sent from my Galaxy S4

Your definition of Lag is definitely different than my definition. However, the "home" button has a short pause because it is designed that way. It is waiting (just a fraction of a second) to see if you are going to use it for it's double tap option or not. Disable this feature (you can search for how) and that very little delay should go away.

change S-Voice setting to not open via home key. home button response delay solved.

You did a 10 minute video for that???? I believe when you say you have OCD. I suggest you to seek professional help, and not from Samsung support

I agree there's nothing wrong with your phone.. But they're might be something wrong with you if a .01 millisecond delay bothers you to the point of making a 10 minute video and rambling on and on about it. I would try and get laid if I were you and stop worrying about the phones home button.. Not that big of a deal

Thank goodness for fast forward or that would have been a painful 10 minutes.
You should all kinds of weirdness with your launcher - how about going back to stock 100% first. But from what I see things are fine. Maybe the mechanical home button is slower then the touchscreen. You could always return it for an iPhone.

Hahahahaha is this guy serious

Limiting the process to four will negatively impact your performance.
More ram usage does not mean more battery usage, in fact it should usually save battery because the applications are already loaded in ram when you go to use them. If you are constantly killing them you'll have to reload from nand flash and back into ram.
Also you should probably try to make shorter videos

Do you have any idea why when I have maybe 5 apps in my recent list my home button response has a slight delay but then if I clear all recent the home button response is basically instant?
Sent from my Galaxy S4

I actually went to at&t yesterday to compare mine to the display models and the home button response was exactly the same, until I started loading multiple apps then mine was a tad bit slower. You guys might think this is ridiculous but I'm just trying to make sure that I don't have a defective device. I have like 6 more days to return it to Verizon if i feel I do.

Yep. Ordered 7/10 got it today 7/12. Opened it. Plugged it in. Nothing. Did the steps that googled emailed me. Nothing. Screen just flickers when trying to turn it on. Awesome. Don't you love when you pay for something, it comes and doesn't work at all??? Guess it has to happen to somebody! So at least I won that... Will update on how long Google takes to send another one.

Many people have the same manufacturing issue... It just didn't usually kick in this early.
There's two things this could be... Assuming you haven't already sent it in.
If the screen is kind of like an antrace and noisy, then it has zero charge and needs desperately, a few hours electricity.
If it only flashes like you say. There is a common issue with nexus 7 issue where the cable hooking the battery to the device becomes detached.
The easy fix I would do in your position would be to slip it open and reconnect the cord, as it is in the front. The case is also very easy to get off with a flathead screwdriver, or from dropping it... Not the best design. I did alot of research when mine was bootlooped and very certain that is your problem. Hope this helps if you didn't send it in xD

Don't mess with it....send it in. Better to wait and start with a fully functional device, not one you had to fix to make work!!

Amen to that! My level of fixing tablets and phones is pretty high. Just got done replacing my Nexus 4 screen. Anyways, point I'm trying to make is... Open box and DOA? I don't think so. Already have the RMA process started. Hopefully this one will work. Should get it on Wednesday.
