[Q] Touchscreen unresponsive on different strips
The digitizer on my HTC One X+ seems to be unresponsive on some strips of the screen.
This problem occurred after I replaced the lcd+digitizer module because the original one was cracked.
First 1 strip of the digitizer didn't work but 1 week later there were 3 unresponsive strips.
Today I reopened the phone to check if the new screen was the problem but after putting the old cracked screen back, it showed the same unresponsiveness but on different strips. I added a screenshot of a draw test in the attachment (since I can't post images from outside links).
On this screenshot, all 5 strips of the bottom half of the screen are unresponsive but sometimes only 2 or 3 strips don't work.
I notice that the screen freezes sometimes while trying to unlock the phone (which is a pain currently). Also the phone gets really slow and sometimes it randomly registers touch all over screen while I don't even hold it.
So my question: Is this a hardware or software problem? and does anyone have an idea how to fix this?
On the side, another problem: when I try to update the phone's firmware I get a notification that a new update is available (this is a very old update from months ago) but when I try to update it, the phone reboots, tries to install the software and then a red question mark appears on the screen. I haven't been able to update the phone for about 4 months now. Don't know if that has anything to do with my current problem but I thought maybe I should mention it.
Thanks in advance.
