[help] glass cracked, won't turn off! - Nexus 4 Q&A, Help & Troubleshooting

So my nexus 4's glass screen shattered today and also the digitiser broke. The lcd still works and the rest of the phone seems to be fine.
Anyway, for some reason the phone is automatically restarting after I hold the power button for 10 secs to force power off. Also the phone boots fine into lollipop and with what little part of the digitiser that works I can access the notification bar and go into settings meaning its operating ok as far as I know.
I have no clue how to diagnose what's causing this, please help!!!
Thanks in advance

Holding the power button causes a reboot, not power-off.

Hold the power button for 20 to 30 second. The Google logo will pop up once, keep holding the button and it should turn off after that.

Touchscreen Not Functioning Correctly

The screen on the my streak has been slowly degrading, to the point where i can barely do basic functions of the phone. It doesnt register touches or swipes a large percentage of the time. If I long press on the background to bring up the add shortcut widget popup, it usually will bring the phone back to 85% function. But if I lock the screen and try again, I have to go back to longpressing until I can click apps.
Often presses will register along the top bar and bring up the notification screen or short menu when I am clicking anywhere but on the top. It has happened several times while typing this.
Has anyone had Touchscreen problems with their Streaks?

Do you have a screen protector on and maybe some debris between it on the screen?
I'd recommend aligning the screen.
User Manual said:
If necessary, you can calibrate your touch screen as follows:
1 Press and hold the power button and then touch the Power off option on the screen to turn off the device.
2 Simultaneously press and hold the volume up button and volume down button .
3 Without releasing the volume buttons, press and hold the power button , until the device turns on the configuration screen.
4 Press the volume buttons to move the highlight bar on the screen to the Screen calibration option.
5 Touch the Camera button to start the touch screen calibration. 6 Wait for the device to reboot.

Also you could enable the debuging mode by typing in *#*307#*#* in your dialer, then in your app list you should see some new apps.
Open up Dev tools the select Pointer Location
Also another one is EmList and then select "Touch_Panel" theres a handful of diagnostic tools there that are pretty fun to mess with to see if something is physically wrong with your screen
Oh and to hide/disable debugging mode, just type in *#*308#*#*
I do also have some screen issues i had 8105 went back to 8023 and was working fine until today that it was acting up, but is better than 8105 which only let me touch half the screen, now it lets me do about 80% of the screen from bottom to top. I do have a screen protector, when I was running 1.6 didn't see this issue. Also i noticed that sometimes when my fingers are a bit sweaty the touch input doesn't work that well.
No screen protector, stock 1.6. Will try debug, thanks.
It happens with sweaty hands with dry hands its just messed up.

I just used the 6 step block method and it seems to have solved my issue. Help very much appreciated!

How long did it take to reboot after you hit the camera button?
I had to do mine yesterday as the lower part of the screen wasn't registering touches properly, as if it was about 50 pixels out.
First time round it didn't boot up with the volume keys held so i popped the battery off and started again (seems to be a common issue with this device). Then it was pretty much as standard for the boot. Keep the buttons held til the menu pops up, choose calibration, leave it until it says it's done and then reboot.
Again, should reboot as normal but if it doesn't try popping the battery off. The rear cover seems to cause a fair few issues with this!!
oh and running the calibration fixed the issue for me!

[Q] Milestone 2 power button repair

Hello there guys!
Recently my M2 power button stopped working, there is no click whatsoever. I checked it up and it seems that the small metal piece fell somewhere inside the phone. I found this dissasembly video : http://www.youtube.com/watch?v=BUXSmlwUC9Q
Now here is my question : it looks like while dissasembling you are ripping the phone apart, is there any permanent damage when trying to dissasemble? I could do it by myself, pasting the metal piece inside but I m a bit concerned about damaging the phone.
Thanks
Strange Milestone 2 power button problem
Hi, I have a strange problem in the power button too, but it's very rare (may be rare just for me)
The thing is that the power button suddenly stops working. If i take off the battery and put it again the phone boots without pressing the power button, and it still not working. Then after some time, it suddenly starts working perfect there is no need to press it stronger then normal.
I can't find out any patterns in this behavior. Another strange thing that happens is that sometimes the button works intermittently and delayed. Example: I do a long press of the power button and nothing happen, then the shutdown dialog shows 2 seconds after. And some times (the most) it doesn't
I'm a little bit confused about it, any ideas?
I've new info: i can't get into bootloader mode (the phone turns on but i get a black screen with no text)
Think I am getting the same power button problem now. How did your repair go?
Same problem here now, dunno if its really related to the power button or something
completely different is going to break down soon.
I will try to replace the whole flex cable with the buttons, but shipping needs some weeks.

[Q] Touchscreen not working on lock and reset screens

In the last couple of weeks, when the pattern lock screen is displayed, it intermittently doesn't accept touch input. If I power off and on the screen quickly, it then accepts touch input fine.
Similarly, if I press and hold the power button (with the phone on), it brings up a "Phone Options" screen, with options for Silent, Airplane, Profile, Reboot and Power Off. Touch input does not work at all on this screen. I'm working around this by using the Quick Boot app.
Otherwise, touch input works fine, so I don't think it's a hardware problem.
I've seen something similar when Google Nav gets in front of the lock screen. Touch doesn't work until I power off and on the screen, and enter the lock pattern. Could something invisible be getting in front of the lock and power screens?

Hey there,
Maybe the ROM h doesnt function properly on your device. Try shifting to another rom. All are equally amazing. If you do not want to shift, try running task29 and start the process all over again

Have you read the thread about the unresponsive touchscreen, where pressing hard on the end call button fixes the screen touch? I assume your problem is in essence the same; once you press it hard enough to actually unlock the screen the touch works fine.

That probably is what the problem is. Btw to everyone, I haven't noticed a difference in pressing it really hard, I noticed that pressing it a lot of times does the trick

Thanks for the feedback. I don't think it's the ROM, been using GBX-v12 since it was released, and previous versions before that.
The symptoms do seem similar to the other thread, but others report it on many screens. I only get it on the lock and reset/power screen. Otherwise, it works fine. However, those screen are brought up after pressing the power key ...
I suppose if it is hardware, then it's likely that cable issue. If it's software, then a reset should clear it, so I might try an ICS ROM from scratch first.

I guess i shoulda commented that how my digitizer began acting, it only did it while in the power menu but after a couple days it started doing it while just hitting the power button to put it to sleep, so i remapped my green phone key to be the power button

Thanks for the tip. You're right about the symptoms getting worse, it now occasionally stops working on other screen
I'm using any button but power to turn on the phone. To turn it off I've added "Go to sleep" to the notification widget bar, which I assume is the same as pressing power??
Not quite as user friendly and sometimes I forget not to use power off, but it'll do for now!

Yes that will work! I used it cause I got lazy and didn't feel like changing the key file but it's much easier to use the green call key instead of the notification power widget

Try this:
Lock the screen normally, screen turns off.
To turn it on again by pressing any other screen buttons other than the power button.
I found that if I do it this way, the screen runs normal.

NEED HELP. Power button stuck.

My power button gets stuck and as you know when you long press it it reboots the phone. So basically my phone is just constantly rebooting and rebooting, its practically unusable. I need help if anyone knows a way to disable the function of power button, I mean so the power button wont do any function anymore, or swap it with another button.
I had the same problem. Got the button replaced, it worked for a month or so and I started getting the random reboots again. A search on the internet reveals that this is a common problem with the S3, and I doubt they fixed the issue for the S3 neo.
1.5 years of use and my power button is broken, my volume buttons are mushy and my camera doesn't focus at all. The build quality on this phone is a joke.
You'll probably have to have your power key replaced as well. Or do what I did and remove it from the motherboard. You won't believe how flimsy the solder is. I now use the accessibility shortcut button to lock / unlock my phone. It's a hassle and it takes up screen real estate, but at least it works.

Mine stopped doing it now but I'm sure it will start again. You are right, build quality of this phone is really lame. That part on the sides that looks like metal is mostly worned off from my phone. Camera focus is crap and volume is lower than before, I can barely hear notifications. Maybe I'll remove the button too, but I'm concerned about how to boot the phone if it turns off.
You can turn on the phone by connecting the charger, immediately booting into download mode (before the battery icon comes up) and restarting from there. It's not the best solution, but at least I have a functional phone until my oneplus x arrives sometime this week
try to do this

That's actually a fantastic idea. I thought about flashing cm that has no offline charging and booting that way, but this is better solution lol.

You can try nova launcher since it has a gesture for double tap to lock screen, or maybe a 3rd party app.
use soft lock to lock screen without pressing power button

Problem with a friends S5. The screen keeps going out.

When I turn the phone on the screen lights up for about a half a second and show the logo. The phone fully boots and all buttons work. When I push the power button to turn the screen on it does the same thing. I can see that its at the home screen. There is no water damage and the phone hasn't been dropped. Sometimes I can get it to boot up with the screen working right. Is this a common problem? What is the cause of this, bad screen, mainboard, software?
Thanks
