Two days back, after coming home, I had applied some sanitizer on the phone (by first putting it on my hands and then rubbing it on the phone). Nothing happened at that time, but after about two hours, I found that the touchscreen had stopped working. The phone itself works, the display works, but it does not take any touch inputs. I used a USB OTG mouse and copied all the data, then factory reset it, but the problem remained. I've also reverted to a previous TWRP backup, but still the touchscreen doesn't work.
Any suggestions, apart from sending it to the service center, which in the end I'll have to do if I don't get it working.
I opened the phone, unplugged the battery and the touchscreen cable, and reconnected them, but it's still the same.
Another problem is that with the reverted TWRP backup, the phone works (using the OTG mouse) but there is no sound during phone calls. This problem was not present before I reverted to the previous backup. The phone's on LOS 15 at present, and I tried to solve this issue by following some guides on the internet which ask for editing the build.prop but the line they ask to change doesn't exist in my build.prop.
Please help.

Hi All,
Something weird happened today. After installing Google Earth update, tried to open Google earth, nothing was visible, only the top bar. After sometime the application force closed and phone restarted. After this, the touch screen was not at all responding. I wan not able to unlock the screen at all. Took out the battery and reinserted and no change in behaviour at all.
The only relief was that when i tried to connect to computer, i was getting "Turn on US Storage" screen and it was responding. But only this screen and nothing else. Tried multiple restarts but no luck. Only after changing the sim card, the phone started responding. After this changed back to original sim and the same is working now.
Any idea how to understand cause of this behaviour? Haven't rooted my phone yet.
I know this thread is old but for what it's worth I believe the issue has to do with faulty hardware.
I had the same thing happen to me yesterday when downloading a wallpaper with Zedge. Even when mounting USB storage from CWM I was not able to keep a steady connection, it was like the cable kept becoming plugged in and unplugs every few moments.
From what I was able to find, it's a faulty part and the internal SD card fails. The fix is to have Samsung replace the mainboard
However, I restored a CWM backup and everything has been fine so far, even reading files from the Internal SD that did not work during the time of the issue.
I am going to have my phone replaced anyway (I'm within 30 days with mine so I don't have to send away).
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

Check out the guide below and hopefully you can avoid replacing your nexus 4 screen or digitiser

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, I am on the Android L preview and recently had to replace the back cover due to the glass breaking. While I was in there, I pried up in the wrong spot and cut the gsm/3g antenna that is attached to the loud speaker. I replaced that and in the process discovered that the wire antenna as almost falling apart too, so I ordered one and replaced that. I am fairly confident that I did not mess anything else in the process, however, my phone has not been working well since. The phone will be fine, unless I use the 3g connection. SMS and voice do not seem to have any affect, however, if I use the browser for more than 2 min, the phone will randomly cut out my 3g/gsm signal and then it will come back and continue to do this for a few min until the phone shuts off. When I boot into TWM recovery, the only thing strange that I notice is that my battery would go from 80% when the phone was on to 1% in recovery, until the phone will appear to have 0% and not boot on (as if it truly had no battery). The strange thing is, the phone will boot back up if I leave it alone for a little while without putting it back on the charger. I have completely wiped my phone, locked it, restore to stock, re-rooted and unlocked and flashed my rom (5.0 preview). This has not changed anything.
I finally was able to capture a bug report. I have no idea how to read it though. If anyone could help I would really appreciate it.
I have attached the bug report.
Thank you!
Okay, This problem started 1 week ago, i've tried everything but nothing seems to work:
My Touchscreen won't work at all, sometimes it works, sometimes it doesn't, this started a week ago when my phone (Redmi 3S fp) got into the water, nothing happened at the moment, i just turned off the phone and gived it some time to brake, then i turned on and i started using it normally, but 2h then, touchscreen stopped working (here's when the weird things started happening), i dissassembled the phone and let it dry, then, when assembled it again and turned on, touchscreen still wont work, but some time left, when i plugged out the sim plate and plugged it into the phone again, TOUCHSCREEN MAGICALLY STARTED WORKING AGAIN! but the other day. it started beeing unresponsive again :crying:
After that happened, i started thinking it was a software problem, checked the logs, but couldn't find anything! then i tried flashing another kernel, and guess what? TOUCHSCREEN BEGAN WORKING AGAIN!, but 1h later it stopped working again Today i decided installing RedWolf Recovery (Thought it has nothing to do with the touchscreen, but at this time am waiting for a miracle) and touchscreen got intermitent, sometimes it will work, and sometimes it wont.
I was thinking of flashing non treble files and see if it fix the problem, thought it has nothing to do with the touchscreen... Am using Nitrogen OS Treble build, Chimera Kernel and last Firmware, i dont know if it is a driver bug or a real problem with the digitalizer.
Any suggestion it's apreciated!

Dissemble your phone unplug battery first then unplug digitizer. in digitizer you'll see some ic's on it's ribbon untape that area and clean it (clean ic',ressitors,cap)with petrol using teeth brush do it carefully let it to be dry then check motherboard as well if you see some water clean it also with petrol use very little drops of petrol clean slowly to not damage any tiny part of motherboard then let it to ne dry also clean all jacks problem will solve automatically

Hi everyone. I have an essential PH-1, dropped it and cracked the screen in a couple of places. It still worked normally, but I ordered a screen replacement from amazon. I was able to remove the screen easily enough because I wasn't trying to save it. I connected the new screen before permanently afixing it just to make sure it worked. So, the screen looks perfect and everything looks like new, but the screen doesn't register any touch response at all.
I am able to use the phone with a USB C keyboard and mouse, I'm writing this post on my phone with the keyboard and mouse. Its got the latest software and updates, and aside from the touch screen not feeling any touches, everything is normal. Does anyone know what might be the problem? I've unlocked the bootloader in preperation for installing TWRP, but the process didn't work for some reason. I'm still reading up on that. Could this be a software issue? I hope it's not a problem with the new screen. Ideas and thoughts are much appreciated.
I've tried everything I think, though very cumbersome I was able to unlock the bootloader, install TWRP and root, and installed the stock image - but still no joy. I then installed Lineage OS but there was still no touch response. I did a wipe first through ADB, before 8 installed the stock image, didn't make a difference. At this point I think it must be a defective screen unless anyone has any ideas I may not thought of? All of this done with a USB keyboard and mouse - switching back and forth disconnecting and reconnecting the phone to the PC to use ADB.
