[Q] New Nexus 7 no touch at all

Hello,
I just got my Nexus 7 shipped, and try to turn him on, but when I want to touch the screen to enter my language the Nexus doesn't recognize any tap. I rebooted the Nexus several times (the buttons on the side are working - 2button combo to reset).
Has anyone an idea what I did wrong or is it a production failure?
Thanks

Very simple i think...... must be production failure when its brand new out of the box.
I would change it for a new one...
Good luck

Faulty touch screen, send it back. I had one like that.

OK, Let's rule out one thing first. On the initial language setting screen, you need to slide up and down rather than to tap it. You know that right?

Need Advice N7 Screen issue.

Hello-
I usually do not open threads but I need advice on this recent touch responsiveness issue that has been happening. My Nexus 7 8 GIG was running great I had not had one issue with it, until one day I opened the case "Poetic leather case with magnet locks" and the screen came on notifications were on and animated everything looked fine. I went to unlock it and the touch screen did not respond to anything, now the screen rotates fine and all but it would not respond to touch. So I reset it with the power button, the touch screen then works until it times out and turns off, I wake it up and the screen does not respond again. I took it out of the case and have manually turned it on/off and it still does not respond to touch, but it will work every time I reset it. This problem has came out of nowhere it was running great.
I was originally on AOKP Milestone 1 with Franko's Kernel r25 so I thought maybe that was it so I re flashed Milestone 1 and kept the stock kernel and the problem persists. So I wiped everything and put BAMF Paradigm on it and it still does this, but the touch screen responds every time it is manually reset so I am trying to figure out if this is hardware or software related I am led to believe it is software considering the touch screen works flawlessly upon reboot but again I am not sure.
I have not added any new apps or anything like that to cause a memory leak or such. This problem started when I left the N7 for two days without touching it, then the problem happened after I tried to use it after the two days of inactivity.
Update: I turned the N7 off for about a day booted it back up now the touch screen is working every time I am confused.
So I still have 7 months on my ASUS manufactures warranty should I send this unit back? I just do not want to think its software related and it will get fixed through updates and then find out it is hardware related and be out of the warranty period.
I am on 4.1.2 with the last boot loader "not the new one"
latest version of TWRP
Thanks everyone in advance for your time.

It seems like a magnet bad effect to me! not sure though cuz the nexus 7 suppose to work fine with magnetic cases but it could be a Magnetic field effect. In my opinion as long as it works don't send it cuz you don't know what happens there in the service center, I mean once the device is opened it would never get the same as before.

Yea I had thought that was it but I took it out of the case and still does it so no dice on that field

well i flashed the latest google image and just started fresh. The touch screen is now working without issue so hopefully it was nothing still not sure though what would have caused this though -_-

[Q] Touchscreen problem: hardware or software?

Hey
I had my Nexus 4 for a while now and today suddenly I have a problem with my touchscreen. It suddenly happend, it didn't fall or nothing.
So, the problem: there is a part of the screen that doesn't function properly. It's at a certain y value or height. It noticed this today when I wanted to swipe down the notification bar. Half the time it flips back up or doesn't do anything at all, sometimes it does work. If I swipe "fast" before that height, it usually works.
I downloaded an app to test the touchscreen and at that height it registers 2 or more fingers or it snaps above or under that line.
Can I fix this or do I need to bring it back for warranty? Is this a software or hardware issue? I also did a reset, but that didn't help...
I uploaded some videos to illustrate (can't post links so insert this in the youtube links please):
1. The problem: /watch?v=kNLbSU0smcw
2. Test: /watch?v=B8ERuBtYeBA
Edit: When I hold the phone horizontally, the notification bar works perfectly.
Many thanks,
Aaron

Update: from yesterday until now the screen was even worse, like I was touching it with 100 fingers, it went totally crazy...
A few hours later it works perfectly normal again
Any ideas?

Ok, I still have this problem...
However, the problem is present and I switch a few time to the lockscreen and back, it's fixed most the time. So I think this must be a software issue.
Maybe undoing a few updates might help? What's the best way to do that?

Are you on a Custom ROM / Kernel? If so, go back to stock ROM and Kernel and see if the problem still exists.

No, never used other roms, kernels or rooted..

Sent from my Nexus 4 using xda app-developers app

I have the exact same issue.. Did you manage to solve it?

Nope, but sometimes I can use it like a week with no problem and sometimes I have it everyday.
At first I thought it might be because of the low temperature in my bedroom, but I tested it and I don't think that's the reason. I removed the cover I bought too, but I need to use it a bit longer to be sure it doesn't happen without cover. After that I'll put on the cover again and check again.

Is it possible that it happens when it is charging? Mine does this when it is charging.

No, as far as I know it's not affected by charging. The first time I had this problem I just picked it up from my desk..

I had touch screen issues as well, less than one month after getting the phone.
Occasionally, after pressing the power button to power up the display, the touch screen would not be responsive. I need to turn off/turn on the display again for it to work. It finally conked out one day when the entire part used for soft keys doesn't work anymore. Just an instant before this happened the touch screen started acting crazy for a few seconds.
Had the touch screen and LCD replaced under warranty.
The problem now is there's a bright white blob in the upper right corner of the LCD, and the proximity sensor sometimes doesn't work, resulting in no display when making or receiving a call.

I have the same problem. I am using an other USB adapter for loading. And while the N4 is charging the screen responds like crazy. It often detects two fingers instead of one... And using the keyboard is impossible... If I use the original USB adapter it works with no problems...

Yeah, turning the display on/off a few times (so lock/unlock) helps sometimes. The warranty is a bit of a problem here, I bought it in Germany (MediaMarkt), but I live in Belgium. I tried registering at the LG site (Belgian version), but no option to select a Nexus 4 there for support... I did a live chat at the LG site, explained my problem and the helpdesk guy just left the chat I tried to contact them using Twitter, but they never replied. I asked MediaMarkt and they said I'd have to bring it in the a German MediaMarkt... It's a long way to Germany, so I'd rather not do that unless I can't solve it and they reject the warranty in Belgium (although they are obliged to).
I'm also worried that I'd get an even worse phone, like the problems you have with your new phone :s

Ok..I have a RaZr and this happened to me too. One fine day. Playing a game. In the middle of nowhere. I was scared. S*it scared. So what did i do?
I just did a soft reboot. Pressing the right combination of keys and the phone reboots.
Also, here is a very long drawn attempt, but can u try doing a wipe data/dalvik/cache?
Go into stock recovery and do the rest.
It may help, it may not help.
WARNING: YOU WILL LOSE ALL DATA while doing this.
And oh: I am sorry but I think this is a hardware issue. I may be wrong.

I had the same issue with my EVO LTE. It would go away and come back just like yours. It wasn't a software problem , so I sent it in under warranty and they're fixing it free of charge.

Broken knock on

A few days ago my knock on broke. I've changed Rome,kernels, and restored a stock backup to see if any of that was the problem and it still won't work. Then I noticed that a line of my my screen is not registering touches. If I swipe across the area it registers, just not to touch. I have a feeling that with a portion of the screen dead it is affecting the knock on feature. Can anyone attest to this or does anyone know what my next course of action might be to get knock on back. I have included a picture of lcd screen test to show which portion of the screen is not registering touch. Thanks in advance!

In having the same issue on my Sprint G2. Only just bought this device 3 days ago and knockon with the screen off stopped working. It works with the screen on in every launcher, but turn the screen off and nothing.
I'm thinking factory reset but I came here first because it still works with the screen on.
Oh yeah, what app ate you using to see the dead zones?

Defective sensor is causing the problem. Only option is to get a replacement.

Sometimes my G2 does not recognize knock on, when I tap on the screen too fast… but this is not related to any particular area of the screen.

The app is called lcd test or lcd screen test. Just an update. The dead zone is gone now and knock on works again. It is more than likely a hardware issue with digitizer and will probably come back, but for now I am getting my knock on.

This is exactly what i'm experiencing!!! Same dead zone for tapping and no knock on! I submitted a service support ticket to LG earlier.

I guess I'll be sending my phone to lg..
Posting from my LG G2 while driving an Evo IX.

As a temporary work around for the dead zone, I recommend installing the one handed xposed app (http://forum.xda-developers.com/xposed/modules/mod-one-handed-mode-devices-t2735815) and toggling it to shift the screen down by 100 pixels. This allows you to move necessary buttons (such as the install button in google play) out of the dead zone temporarily.

I've sent my phone back to lg to have this corrected. Seems a little silly that I have to work around a dead spot on a new phone with less than two months of usage.

Exactly same issue here on my vs980 with dead spot in exactly same place. Weird...

Okay folks. Knock-off works, but Knock-on doesn't.
Turn off the setting in the gestures menu. Reboot your phone. Turn on setting. Power button lock your phone.
Now tap screen firmly for one second then tap firmly again. (No quick tapping like you're trying to turn the screen off)
Say this out loud. (1.- 2.)
One dot, two dot.
The first touch has to be firm and for a solid 1 second.

Well it still doesn't work. Regrettably...

I have this same problem on mine now....
I wish we could figure out what is causing these issues....Has anyone flashed TOT back to stock ZVC to see if it takes care of the issue?
EDIT:
Fix For Me:
Since Sprint doesn't have the update touchscreen driver,
Goto: Device Test-->Individual Item-->Touch Draw Test - Auto
Draw the outline as close as you can (notice the touch screen works everywhere!) then press your power button.
It will ask you PASS FAIL - SELECT PASS! (trying again if only Fail - but it worked on fail too for me)
NEXT:
5689#*980# (From Dialer)
Goto: Device Test-->Individual Item-->Touch Draw Test - Manual
Draw the outline as close as you can (notice the touch screen works everywhere!) then press your power button.
It will ask you PASS RETRY FAIL - SELECT PASS!
Exit, your touchscreen should be responding now that was previously dead.

This worked on my Sprint G2!! First time the dead zone (btw, it's always the same region at upper half of the screen, compared to other people's screenshots) happened, I thought it was the running out storage space, because after I transferred some of the photos out, it worked again. This morning, same thing happened and I moved all my photos out, leaving 3Gb free space, but did not recover. Tried the update touch firmware method, not working, but this one worked (my Touch draw test auto actually failed), but still after the manual draw test and reboot, it worked.

Sadly, it kept happening to me and eventually the method I used stopped working. I sent the phone since it was under warranty to LG. They replaced screen and digitizer. Took care of issue permanently. Sorry for bad news, but it will prob get worse till you have to replace too. ?

You could flash stock rom with nexus rom toolkit to discard a software problem but if the problem persists, it sounds like a hardware issue and you should think about ordering a replacement if your N4 is still in warranty.

If back to stock fails too, you might try this mod to increase touchscreen sensitivity, but be careful I think only works on 4.2.2

If the issue is the same while at the recovery I am afraid to tell this is most certainly a hardware issue. You can try and install other kernels and mess around with screen sensitivity but I don't think it will help.

this is weird, I came here to ask for the same exact problem. I also have a part of the touch screen unresponsive, although at the very bottom (navbar unusable, I'm trying to make do with Pie Controls for now, god bless these guys. Highly recommended). Since the problem persists on recovery I though that alone ruled out a software fault, but it seems I'm not alone. I'm trying to understand, did it happen *just* after you guys upgraded or after a while? I'm on 4.4.4 since it came out and my display started acting weird only a couple days ago.
Also, did you receive any warning / strange behaviour before complete unresponsiveness? My screen seemed to registered "phantom presses" at the bottom margin of the display (in developers options I have activated the "show touches" feature), it seemed like I was on a swiping frenzy through the whole margin.

I noticed looking through google's official help forum that users affected by this generally have also experienced some sort of energy dispersion / bad isolation from whether the battery or the charging port, it's not clear. Namely, it seems that while charging from either a wall plug or a laptop / computer ghost touch phenomena and the like are more likely to happen. I can confirm these issues, although I didn't give them that much thought when they showed up.
(Also, it seems the majority of users have problem at the bottom of the screen / "nav bar").

This happens way too often. The wall charging socket at my workplace makes my phone go nuts whenever I connect it there. Touches are misunderstood (typing for instance is a bloody nightmare. Home button or recents button get "pressed" automatically). I've never seen this problem anywhere else. Looks like I'm not the only one. Hm!

Funnily enough, this phantom touches nonsense sometimes happened even when the phone was in my pocket. It would unlock the screen itself (Hellscore kernel allows swipe2wake, so phone would wake itself up) and start registering touches frenetically. The screen would refuse to acknowledge my touches; I was repeatedly forced to hard reboot the phone. This problem magically fixed itself, and reappeared a fortnight later. It turned out to be a digitizer issue; after getting the display replaced, I have no more issues. All is fine except for the mysterious wall charger touches.
Looks like my N4 loves to be touched. Dirty little boy.

I Have a very Strange Touch Screen issue in my Nexus 4
A part of the screen is not touch-Responsive. It only happened recently from Last 2/3 Days,Never had this problem before.
The weird thing is that it looks like the same middle part of the screen. Its a horizontal section in the very middle.

Hello everybody,
I'm Maria, I came here looking for a not too much expensive solution to repair my broken glass and my touchscreen but I foud out I have the same problem ; a band in the middle of the screen is unresponsive. But my problem come out after my poor nexus fell to the ground :crying:
Now I wonder if this is closely linked to the impact with the ground or it could be the same as your problem?

Hi guys!
I had the same issue - navigation bar was untochable in any position (vertical & horizontal). Flashing stock & other alternative ROMs did not solve the problem.
So I returned my N4 to my seller. He accepted the warranty issue and replaced during the reparation:
1. Screen. So I have a brand new screen.
2. Mother board. So I have a new IMEI.
So this isue is rare and has hardware reasons.

My dad has the same issue on his phone, only happened the other day
Happens in TWRP as well
i flashed Philz CWM and the nav keys work there, also in purity if you set the nav bar to 52 (stock is 48 i believe) the nav keys SLIGHTLY work
its weird because the nav keys dont work, yet i can swipe up and get google now?

The swipe up is triggered by a point just above the home button. The bar has no work there.

I been getting less and less of this after factory reset. One thing i learn is to keep my phone cool and also taking off the case. I figure that the overheating a tight grip on the phone is causing the phone to have these seizure like symptoms. Anyone know a rom i can flash to converse battery and keep my phone from overheating?
