Middle of the screen not registering touch - Nexus 4 Q&A, Help & Troubleshooting

Hey guys, my N4 has all of a sudden stopped working correctly. My display doesn't register touch going horizontally across the middle of the screen. Especially where you adjust the brightness and sound. It really sucks and a factory reset doesn't help. Anybody heard of this? Any help offered? For what its worth, I'm unrooted with an unlocked boot loader.

Momentary black screen

Anyone had this one? Since 4.2, the screen momentarily goes black, with a similar transition to hitting the task manage soft key, but transiting to the left in landscape, then flicks back to normal use. Happens in apps...screws up some games, puts others into pause mode as if a task has been switched. Thought it might have had something to do with auto rotation going a bit bonkers, but not sure....
Not heard any reports...have looked through the forum, couldn't find anything.
Weird...it just did it then....but the keyboard stayed on screen, xda disappeared to the left...
Any thoughts and thanks in advance

Ok..just happened again while in portrait mode. Definitely saw it flick to landscape. Rotation is locked btw.
Hmmmmm.....

It happened to me three times last night after update to 4.2 :crying:
Ok...so, while sitting in a tedious meeting, Nexus in landscape, propped up with its folding case the screened flipped upside down and stayed upside down. 3 times. My ipad using colleague giggled.
Any way to recalibrate the tilt sensor? Or any other suggestions?
It's not the end of the world but...there must be a patch solution or other? Before 4.1 I used the auto rotate app, I forget its correct name...
Thoughts?

I used logcat to monitor the Nexus 7 until the random rotation happened. After looking at the log I realized that it was always the same process being activated and that process was nVision.
Since nVision always rotates into landscape mode I was suspicious that perhaps when it tried to update itself in the background it was changing the screen orientation. I disabled notifications and then uninstalled the app and the problem has completely gone away. I have had no random rotations at all in the last 24 hours.

Okie doke.
For the record.... 48 hours and no random flips to landscape and back. I'd be willing to be a substantial amount of money this was the culprit. However, whether this is a 4.2 issue per se vs. Bad behavior in nVision is an open Question.

Ok. Disabling nvision notifications still flips out. Will uninstall later.
Thanks again

Uninstall it. I still think it checks in and screws your screen, whether it shows you the notification or not.

Uninstalled...all good so far. Woooooo!

[Q] Stuck after phone call

I bought a Nexus4 a couple of weeks ago. I constantly got this issue, it will be stuck and not return to the normal screen even I keep pressing the power button. However, if the other side of the call hangs up quickly, it normally works fine. but if it is directed to a voice mail box, it will be stuck forever until I shutdown the phone.
Just wondering has anyone experienced the same issue ?
Have you put a screen protector on it?

It sounds like the proximity sensor on your phone is being blocked you might want to try not using your case and see if its make any difference

Annoying touchscreen problem

Hey guys,
So my N7 seems to have gone crazy. I can't even type, scroll, zoom in/out or swipe or do anything on my nexus 7. I enabled the "see screen touches" option in settings ...
The problem is that it get this random touches on my screen. And when I actually touch the screen it does not record my touches... Sometimes I'm watching a video
and it will randomly pause it because it recorded a touch..
Any of u heard of this issue??
I was trying to type it on my N7 but I couldn't get past the title for the thread :banghead:
Thanks I'm advance

Screen sensitivity

Been having problems with my screen lately. Its hard to explain but some of the screen isn't responding to touch.
I'll click on find on page in chrome and it will go to the option below it. Seems to be very unresponsive too. Some of the keys dont work when typing. When I press the power and unlock they start to work again.
Running PA beta 4 and more recently beta 5 both with the same problem. Pretty sure the problem came half way through using beta 4.
Anyone know what's going on?

Basically when I go down from where that pointer is it is unresponsive. Anyone know why this is?

G2 not registering the second touch when playing games

Hey guys. I'm asking to find out if anybody else has experienced this and if there's a fix for it.
The first time I noticed this problem was when I changed the settings in the game 'traffic racer' to manual speeding and touch steering. It would play well for some time, but then it would stop registering the second touch sometimes, so you would have to touch it twice or thrice for it to register. I thought the game was badly coded, but today I downloaded Real Car Drift Racing and with manual throttle and touch steering and the same problem occurred. The phone won't register the second touch.
I tried updating touch firmware in hidden menu, tried to see if the phone registered all my touches in the hardware test and it did (but I won't do it again since I don't know how to get out of it without rebooting).
I'm stock unrooted D802 running the 20D firmware. Thanks in advance.

Lg G2 have some issues if the screen protector is bad quality.
Try to remove it if you have one and then check again.
If you dont have a screen protector try one more time to update touch fw through hidden menu.
just a random thought.. but does turning off the knock code help?
bit late edit.. I meant knock on, but I guess it hasn't anything to do with it
I'm using a 35 dollar tempered glass screen protector - it could be that my fingers get sweaty and that's what causes it.
I don't use knock code =) it's too inaccurate for me and the fact that the LED doesn't light up when the phone is unlocked bothers me =) thanks for your responses.

The problem seems to be heat. The g2 has problems detecting a touch when the area is hot. This could be due to the glass screen protector, but it's definitely annoying.

Yes indeed g2 have some issues in general with screen protectors.
I have tried almost everything and stop to an x-one tempered glass but i can see is not the same as without anything.
Best feeling is without but scratches waiting just around the corner...
