Touchscreen stops responding for some while - G2 and Desire Z Q&A, Help & Troubleshooting

Hello everyone,
I have a big problem with my HTC Vision. After I've carried it around a long time in my pocket pants the screen do not respond, only after I turn it on and off several times (2-3 times) i can unlock the screen. And then after unlocking the screen it takes about 5 seconds until the screen shows a strange behavior. e.g. for an entry with the on-screen keyboard several keys will be entered without touching the screen, or on the home screen the cursor moves somewhere and activated anything without touching.
This happens everytime i turn off the screen and turn it on some seconds later (maybe 20-30 seconds).
After about 15 minutes out of the pocket the behavior is normal again.
During this about 15 minutes a reboot wont help.
Please can someone help me thank you in advance.
I have the latest CM7.2 rooted on my device, but testet with several other roms.
Greetings Steffen

try to restore stock rom and drivers. If it doesn't help, give HTC for warranty.

i have tried the stock rom as well as other sense roms or other aosp roms.
The warranty is long gone.
thanks for your help.

Then best guess is it needs a new digitizer, next best guess is the main flex. I would be surprised if it weren't one of these two

Thanks for your suggestion, i also think that the digitizer may have a problem, yesterday i bought a screwdriver an repair set for the phone, and then i will open it for looking inside an maybe see something or for only clean it.
But another question, what is the main flex, i never heard about it in past.
Best regards Steffen

It is the cable that allows all components to be connected as you slide the keyboard

No I have not changed it yet, but I have my device completely disassembled down to the digitizer and thoroughly cleaned. But I've noticed no change.
I'm going to buy now, probably a new digitizer and replace the old.
I still remembered that I had such a problem already with the stock-ROM from HTC, just was not as strong and that is why I have not taken so seriously.
I will write my experiences then here in the forum.

Changing the digitizer fixed similar issues on my device.

Thank you for this information, that encouraged me in my decision to buy a new digitizer.
Did you have problems with the sealing tape?

Unfortunetly it is a hardware problem because I dropped my phone last month and the screen was turning on automaticly so I sent it to samsung to repair it.
It happened on my s2 and so I sold it.

even with the screen like that, you can try to connect it to the pc to unroot through adb, and if that doesnt work try flashing stock images with fastboot before sending it in
if none work, just send it like that to samsung or whoever

Its an hardware issue brother. Try using a toothpick or any small pin to lift the middle part inside the charging port. Do it only of ur phone is not under warranty. Or else just ask for a replacement. The google/samsung guys have acknowledged this problem and m sure u wont have any problem in getting a replacement.
And in the meanwhile use only the stock charger which came with the phone. Do not switch between the usb cables. Hope it helps

Thank you so much!
pushing up the middle pin fixed the problem for me!
i think i pulled out my phone out of the charger the wrong way bending the pin downwards. :victory:

Cam doesnt work anymore

Hi,
my HOX fell down this night two times.
This morning i wanted to take a picture, but my Cam doesnt work??
When I want to open the Cam App the Cam Window appears but its black.
The Mirror doesnt work neither.
Is this a Hardware or a Software Issue?
My Phone is flashed
Sent from my HTC One X using xda app-developers app
I think if you dropped it and didn't do anything to it software wise its very probably a hardware issue
Sent from my HTC One X using xda premium
Reflash it to make sure it isn't a hardware failure.
If it still won't work then, the hardware is dead

The warranty does not cover excessive physical abuse. Usually whenever you buy anything, accidental damage is not covered, which is why you can buy insurance.
Same thing happened to me after the 4.0.4 update ( black screen no camera or mirror ) , after few restart it's started working again .
Same problem here cam stopped work for unknown reason haven't droped the phone added new software or anythink like that.
Worked one day and next day it doesn't
HTC will tell you to try and clear the cache

[Q] HTC one x - nothing but static on screen

trying to help my friends daughter with her phone.
It started doing this, and she saw online that she could gently flex/twist the phone to maybe fix it and ended up breaking the screen.
I replaced the screen and the phone is still like this.
I can power the phone on, and hear the startup tones, but thats it.
help! any ideas?

help Touch screen automatically working in standbye

Sent from my HTC Desire Z using xda app-developers ap
Help any one ,my desire g2 touchscreen is automatically working without any touches.when relock d screen it work normally.I changed so many custom roms but same problem.
First, a few things that should be clarified in my opinion: Did the error occur suddenly or after you did something? How old is your phone?
To me, it sounds like the well-known issue with the connector cable degrading. To my knowledge, it connects screen and digitizer to the rest of the phone and is known to cause the digitizer to go wild. The easiest and least expensive would be replacing that cable.

Or where exactly you had the problem?
I'm getting mad at my DZ. But since i love my Phone, its hard for me to replace it with some other phone(without physical keyboard).
Please do share with us.
