This morning, my touch screen suddenly stopped working. Hardware keys are still working but device is not responding when the screen is touched. Already tried a hard reset but no success, now I am stuck at the align display screen. Also can no longer get to the bootmenu, so can't reflash my device! Any suggestions on what's wrong or how this can be fixed? Thanks for any help!!!!
I'm curious
Didn't you see any spots (like oil spots on the water) to the touch screen ?
I had the same problem .I replaced the touch screen and the phone is working again .
No, nothing, was working fine at night, when i woke up just randomly stopped working. The display is not cracked or anything, so wondering whether a screen replacement will do the trick? ALso strange that I can no longer get to the bootscreen to enter HardSPL...
Had the same problem, the issue (with mine anyhow) was the digitizer, which is an overlay that sits on top of the actual LCD screen to give it touch capability....
good post here
http://forum.xda-developers.com/showthread.php?t=392301&highlight=digitizer
I had a similar problem,
To get past the Align screen I had to apply pressure to the top of the screen opposite side of front facing camera - then use the screen as normal
I reflashed the original rom (manually getting to bootloader) - it worked for a bit but ended up sending is back to 02 for repair.
All they did apparently, was to reflash the ROM again and its been working since.
Had the same problem a couple of times a while ago, when i was trying out WM6.5.
All buttons worked but not the touch screen. Never really found out exactly what the problem was, but the first time I managed to get it working again by resetting the alignment:
While gps button pressed (under green button), press center D-pad button this will bring you to alignment screen.
The other time the "alignment trick" didn't work, but i got it working again, after flashing the original ROM couple of times. (And doing hard reset between each time)
I think I used this ROM
You say you can't get to the boot menu, do you run hard-SPL?
most likely its an hardware issue - had this one too, of course out of nowhere!
flash with original rom and if you cannot align screen (as the hardware seems to be broken) send it in for repair. it will be under guarantee, if screen isnt broken.
I had similar problem, I passed the alignment but i had a huge offset in the touch.
I replaced the touch screen and it solved the problem.
You can find it in ebay for 1 US $.

Thanks for all the help guys!!! I do run hard-SPL and have flashed many ROMS - just don't know why it won't enter the bootscreen anymore when I reset the device and press the camera button. Did manage to upload original ROM again by using activesync, now trying to restore original hard-SPL so I can send off the device for repair.
Hi, i had also the same problem, i find a threat in the internet... try to push the upper corners on the device with your fingers and then tab on the screen to see if the problem solved.
I had the same issue.
Its more than likely your digitizer. I tried flashing 100 different roms but always stuck at the align screen stage.
I actually have the barely used digitizer if anyone wants it (for a few dollars of course hehe) My mainboard died a couple of weeks after i installed the digitizer.
needless to say i moved away from the ****ty build quality of HTC to the MUCH better build quality of the iPhone.

I had that problem before but i couldnt fix it my self... the best solution is to send it to the warranty and if they detect the problem they will provide you a new u8800, at leats thats what they did with me. maybe it's a problem with the screen itself

I'm sorry to tell you this, but it sounds like a part of your phone's touch-screen digitizer is broken. This happened to me four weeks ago, and I just got my phone back from warranty repair today. If you are not within warranty anymore, it is possible for you to order the part from Ebay, for example.
Of course, you should try restoring your device, before you rush to buy new parts, to make sure it is a hardware issue.
Additional information:
Unfortunately, I am unable to post links, but you can find the part on Ebay by searching "U8800 Touch Screen Digitizer".

You could analyze what is happening on the screen by going to System settings > Developer options > Check "Pointer location", and possibly "Show touches".
Of course, this is on Aurora ICS and I do not know what ROM you are using at the moment.
If you are using some other ROM which does not have "developer options", you can go to the Play Store and download an application called "Screen Touch Test".
it's digitizer for sure
My brother and a friend had this problem. Its certianly digitizer and it must be replaced. In turkey warranty covered it.

Hello, suddenly my softkeys stopped working, I already tried doing a factory reset, reflash a different rom, but still no go.
What's strange is that even on landscape mode the keys dont work.
It doesn't seem to be a problem with the touch screen since the touch screen works fine as long as the soft keys aren't present.
Any help? Thnx!

Hi Salvy,
Did you flash a mod or another kernel?
It's a very common problem with the Nexus 4. I've been using paranoid android pie for 6 months to work around the issue. I can confirm that it is a hardware issue and not a software problem. A quick Google search can tell you that.

Got the same damn problem. I would normally use a smart phone for at least 18 months but the Nexus 4 only lasted 14 months. I was hoping to use it till the Nexus 6 came out but after sending it off to be fixed, using a dumb phone for 10 days and the phone came back with the same problem, I had to go buy a Nexus 5
My soft keys work in portrait but not in landscape. I enabled the 'show touches' option in developer mode and I can see the lower 4mm of the screen isn't registering any touch. Do a quick search on Google and you'll find there are loads of people out there with the same problem. The only solution is to change the screen and I haven't seen anyone manage to get it changed under warranty . I have sent it back and expect them to fleece me off £100 for a new screen.
Disappointed with the quality of the N4 but I had no choice but to get the N5 even though it is also by LG cause once you go Vanilla, you cant go back

Ok. so I have been told by the LG service centre in Mumbai that this happens when an android update doesnt get installed properly, it definately is an android update problem according to the service centre. But since i am out of warranty by @ DAYS I have to pay Rs. 5300 for no fault of mine... ****ed up!!!
I found a solution somehwere on the internet!!
I had this problem for the last day this is the solution.
Download the application: GMD Auto Hide Soft Keys ★ root
Use it, toy with it and restart your phone. And it just works.
This worked with unrooted phones aswell, as the solution said. I don't know.
Your welcome!

I paid Rs 4700 which includes service charge, taxes etc in addition to the cost of the screen+ digitiser. The guys at service center dont have separate screen and digitiser but just both of them as single replacement. I just hoped that they could have better service centers and support, but you cant help.
Using `wm` command on phone via ADB shell to add an blank border on screen

I used virtual buttons for awhile, but in the end, discovered a way to do it without rooting, so long as you have the `adb` command line tool installed for development, and don't restart your phone that often:
From a command-line termal:
```
# Log into a device connected via USB.
# (Look for a tutorial on using adb, as it need some config on the phone)
adb shell
# Change the screen "overscan" using the window manager tool on the phone:
wm overscan 0,0,0,80
```
The trick is that, overscan essentially adds a buffer (black bar) on any side of the screen for positive numbers. (the screen extends "offscreen" for negative ones.) `wm --help` will show you that the accepted format of overscan is:
```
wm overscan [reset | LEFT,TOP,RIGHT,BOTTOM]
```
ie. you can either reset it to default, or set any border. In my case, I set the bottom border to 80 pixels, and that was enough to avoid the non-responsive section of the touch screen.
Of course, I assume this reset on reboot, but haven't tried yet. If it does, I'm sure someone can figure out a clever way to make it persist
Anyhow, hopefully this helps!
Found the issue and got it fixed
It worked for me. I had the same Problem and it occur when i bought new power cable. The i plugged the original blackberry micro usb cable for power up and it started working for me. Its weird but the cause of the problem is when i plugged the cheap micro USB.
Note:- this is my first update to any forum just to help people if someone has the same problem as mine.

found solution in Chroma ROM
Hi Guys, was using CM 13 Android M, Soft keys stopped working. Tried flashed with multiple CM 13 nightly. No luck. Finally installed Chroma ROM. Over there keys are working fine.
I experienced this issue tonight and was able to fix it quickly.

Issue:
-Softkeys not working when located on the side of the screen closest to the charging port. Softkeys would work when the screen was rotated such that the softkeys were located on the side of the screen closest to the headphone jack.
Device:
-Nexus 4 running 5.1.1
Conditions:
-Battery was 85%-90% charged
What fixed the issue:
-Plugged the phone into a USB charger. I did not use a Nexus charger; I used a random LG charger I had laying around.
-Pressed and held the power button for 30 seconds. The phone powered off after ~10 seconds. Shortly after the phone powered off, the notification light flashed red for the remainder of the 30 seconds.
-Powered the phone back on. When the phone was finished booting up, the softkeys worked again.
What didn't work:
-Restarting the phone multiple times
-Restarting into Safe Mode
-Disabling Chrome (Settings >> Apps >> Chrome >> Disable)
hello people, I lve had my nexus 4 for a while now, never experienced any problems with it on 4.3 neither with 4.4.2, just the overheath thing when browsing websites and such, but recently ive been getting this unresponsive touch in the middle that's not letting me send messages or organize the apps on my main page, I'll explain a little below.
When I slide my finger from top to bottom, just in the middle of the screen my touch seem to go slower and then it like makes a jump and won't recognize the touch in one part, that happens all along the middle of the screen is not just a blind spot, when I write a message and try to send it with the keyboard open, it won't let me touch the "send" bottom I have to minimize the keyboard to be able to send it because the bottom is just in the area where my touchscreen is not working correctly.
I downloaded multi touch tester to verify my touches and I found out that if I make a touch in the middle where I have my issue, the multi touch is recognizing 2 touches at the same time, I'll upload the picture to show how is it recognizing my touches in that specific area.
I'm actually using stock nexus 4 with stock KitKat 4.4.2, I haven't root or anything ever, is the first time I have issues with this phone in the touchscreen, I've also been experiencing some touchscreen freeze where I can't touch anything because it won't work and I have to lock screen and unlock it again for it to start working again.
what I have already done?
I have restart my.phone a couple of time and won't work
i have factory reset it and won't work
I have full charge it with USB and laptop and won't work
and that's about it, I'm sure is a software issues because my phone hasn't drop or anything it just started random and sometimes the phone start to work correctly with no issues but most of the time its not working properly and is frustrating.
PD: sorry for my bad English, not native speaker.
well is not letting me post pictures cus I'm new.

I am facing the same problem. You got any fix for this? Please help....
If you've already did a factory reset I doubt it's a software issue. However you can use one of the guides here explaining how to flash a clean stock factory image. This is the last solution that will eliminate any software sided failure.

I am also facing the exact same problem for the past two days, My phone is in perfect condition, not dropped or anything like that.
I think I did some google play updates which where pending for long time.... Do not know what is causing this.
Anyway have started to uninstall the app updates manually, lets see.
A flashing will rule out all software issues. Check whether the touchscreen is working. Enable developer options, then select "Show pointer touches" and the other one just below it (too lazy to check up and tell you what it is; pardon me )
If you're getting normal touch response over the entire screen, then you're facing a software issue. Anything else implies a hardware issue; this may or may not fix itself (somehow; gremlins.)
In either case, let us know what happens. Cheers!

I'm having the exact same issue & tried what you just said. Unfortunately, I'm not getting touch response in one center row of the screen, for that entire row, no resppnse at all.
Is this the problem with touch screen?

Say goodbye to that display. I have to get my display replaced too (clumsy fingers grumblegrumble) and the LG guys say the display unit costs 3750 rupees to replace... Get it done ASAP.
Greetings!
If it is a software issue try re-flashing the stock factory image might as well work

Hi,
I updated my Moto X Style to Nougat using OTA; that was followed by a security patch update OTA and that was also successfully installed (patch date 1 August 2017).
Post that update, the Back, Home and Multi-Task buttons on my phone do not work, work randomly, generate ghost touches (Multi-Task button predominantly). These ghost touches, suddenly show multiple tasks, exit out of application(s); change the active application to BG and bring forth the Task in BG to front, Split screen in 2 windows (Nouga) functionality.
Technical details of my phone -
Model/SKU – XT1572, 3 GB Ram, 32 GB ROM; this is dual sim device
Android Security Patch Level – August 1, 2017
Android version – 7.0
Baseband_Version – M8992_1255331.29.01.88.09R.CLARK_EMEA_DSDS_CUST
Kernel Version – 3.10.84-perf-g0653b98; [email protected] #1, Tue Aug 1 00:17:12 CDT 2017
System Vervion – 25.201.3
Build Number – NPHS25.200-15-3
I have tried many of the suggestions provided on MOTO Help forums including Cache partition erase and Factory data reset. No changes to Symptoms so far.
When the buttons do not respond to touch, the phone works fine; I can check my mails and respond to them without interruption by these ghost touches.
I tried to follow procedure to revert back to Marshmallow, however, the MOTO site that provided unlock code for bootloader, informd me that the bootloader can't be unlocked. Therefore the reverting option in technically dead for me.
As a workaround, I have installed an APP from play store that provides the Back, Home and Multi-task button functionality without interfering with other apps.
Can someone help and provide suggestions on what I should do next to identify root cause for this problem?
FYI -
I have raised issue with one of the Executives VP in MOTO Support department. But, as usual, their response that the device needs to be checked at service center. And, I think, they are going to go through the same steps and finally the diagnosis would to change the digitizer.
But, I think the digitizer is fine sine the on-screen keyboard works fine; it's keys appear in the same area where the section for Back, Home and Multi-Task buttons appear on screen. I can drag down the lower screen (in split screen mode) all the way down to the bottom end of screen by touching the border between top and bottom screen parts.
Thank you for your help in advance.
Warm Regards,
Ravi
PS: Apologize if this issue has already been addressed/resolved in some other thread. Could not get time to go through available threads in this forum to see 'em.
i am also facing same issue with the same BUILD number and when i have contacted MOTO customer they have informed that its a malware issue and touch issue and need to be repaired and they are charing Rs 9k. Issue start after upgrading to this version and not able to downgrade now and
One point that I noticed (and may be others too), if you rotate the screen, the nav-bar with it's Back, Home and Multitask buttons also changes side and works perfectly. However, any time you comeback to home page, the homepage is always shown in portrait mode, the nav-bar moves back to it's normal place (just above mike end of phone); and, lo and behold, the problem starts.
Do you have this symptom too?
Also, if MOTO service center is asking you 9K for issue resolution, I suggest that you get them in writing each individual activity that they will perform and what issue with the phone that activity will fix. Looking at the price, it seems that they have told you to replace the LCD Screen/Digitizer.
From what I know and observed with my phone, I do not think it's Digitizer (Touch Screen) issue. It appears to be more of software issue. Reason I say this because, when the nav-bar is in hidden mode, this problem does not happen. Also, if the screen is locked, you can still activate Camera or Mike by pressing in lower right- or left-hand corner. It's only when nav-bar layer comes up, the issue starts.
Are you able to use the onscreen keyboard? If yes, then I can say with guarantee that it's not Digitizer issue, because some keys in the keyboard (Space bar, some punctuation keys) are in the same area that nav-bar overlays when active. Check with the MOTO Service center why it is so?
Warm Regards,
Ravi
I recently got this issue and found this thread after researching. It seems to me there's no clear solution for this issue.
What happened to me was that I had no problem after upgrading to Android 7.0 but I started having problem after trying to restart my phone many times in a row because of the battery was dead. Since then it never came back to original even after changing the battery.
The camera quick start on lock-screen still works fine so I think there's some issue with software itself. I might somehow wipe off some code in the phone?!?
