Touchscreen dead?

Hey, recently I was just using my phone and it wouldn't respond to any of my touches / screen presses. I tried doing a factory reset (using CM 7 stable), but it still doesnt work. The menu buttons arent working either, but the trackball works fine. If I press REALLY hard down on the screen it registers my input. Any idea what happened or how I can fix it?

Was playing with a phone just last night with a non-responsive touchscreen. Couldn't get past the "Touch the Android to Begin" screen after reinstalling CM7. I found that if I gently pressed and twisted the bottom of the phone around the trackball, the touchscreen would come back. Give it a shot.

Have you ad trouble with this from before? Try installing another rom with wipe

[Q] My Xperia Z is controlling itself

Hi guys,
I recently got my Xperia Z back from repair. I had it in because when I pressed the power button to unlock it, sometimes the screen would stay black and I wouldn't be able to see anything, but I could still use the touchscreen.
So I got my phone back with a new LCD screen and it's been a week now and it hasn't had that problem at all, but I'm having another problem.
My phone is randomly controlling itself. When I unlock it, every once and a while it starts pressing all the buttons on the screen. Opening up the task manager, swiping left and right, opening up the camera, etc. Just going completely haywire.
So to fix it, I tried a factory reset, but that didn't work. Then I got a new update for android, and for about a day it worked perfectly but now it's back at it again and controlling itself, pressing all the buttons etc. I had an alarm set this morning and I couldn't even turn it off because of it.
It's completely stock, I haven't even tried flashing or rooting or anything like that, and I'm running Android 4.4.4. Model number is C6603.
Anyone know what could be causing the problem?

there is some issue with touch calibration or some issue with the digitizer.

Well it happens before I even touch anything on the screen, so would that point to the problem being the digitizer?

[Q] Phone gets to lockscreen and reboots

I installed Words with Friends and for some reason the app gets stuck on a black screen. So I powered off my phone and turned it on again...... and now everytime it gets to the lockscreen it freeze up and reboots. Help?? I'm able to unlock the screen now, but after a few seconds or so the phone just freezes and reboots.
I have a Z1S so there is no hard factory reset available. It also freezes in Safe Mode so I have no idea what to do now.
Was able to get to factory reset in the phone so I'm fine now. If a mod can close this thread or something.

Ota AT&T lollipop upgrade leads to black screen on unlock attempts

Hi. I am having issue where phone will not come out of lock screen. Buttons light but screen stays black. I can reboot and use phone so I know it is not hardware. I can still blindly touch screen and maybe get past lock but stays black til I reboot.
I have tried cache clearing and full reset to no avail. Only option I see is full root and alternate rom.
Please help

Phone Freezing Shortly After Startup

Starting this evening around 5ish my phone has suddenly started freezing, every app I open "stops responding" and eventually just goes to a black screen with the navigation buttons at the bottom, but the buttons won't respond when pressed. The whole process from startup to complete freeze is roughly five to ten minutes?
I've booted into Recovery mode and wiped the cache partition, I've uninstalled any new apps that I've added this week, I've cleared the caches for Google Play Store/services.
I can't even get into settings to do much of anything because it freezes too and won't respond.
The phone also seems to be running kind of hot?
Any ideas please? It's a stock Blu R1 HD, no root or anything.

Being that you are not rooted, the only option to try is factory reset from stock recovery. And if that does not help there is nothing you can do.
