HELP !!! | Touch Controller gone crazy !

[Bar Bokovza]

Hey,

My 820 had a problem with it's digitizer - there was a line in the middle of the screen that didn't react on touch.
Therefore i've asked for changing my digitizer.

The screen now works with the touch, including on all of the areas, but after a period of time since reseting, it starts to go crazy and sometimes - i can't even answer a phone call only because the touch is not working.

After reseting (every 30 mins) the touch is working. I've replaced digitizer 3 times, did hard resets, including the nokia tool. but nothing.

here's a video to show you what is the problem - here it reacts to touch, but not accurate at all.

Do you have a screen protector on your device? It looks like the phone is registering your touch, but is also registering another touch or input from somewhere else on the screen at all times.

There's no protective layer.
Sometimes it's doing that and sometimes it's not responding to touch.

Are you 100% sure that the replacement part was an genuinely original OEM part?
If not than that could be the problem.

That's the one thing that I didn't check that out.
I've ordered today an OEM Digitizer + Frame, so I won't damage the phone when I'll replace the digitizer.

I thought this new "screen" is not OEM because of the buttons under the screen - They don't look sharp and white like the original screen.

UPDATE - When I tried to wake the phone using double tap on the screen (like in the LG G2) it didn't work in this "screen".

Did you replaced to an OEM part and it was working good ?
