UNRESPONSIVE TOUCHSCREEN after 3rd NEW replacement digitizer.

As the title says, ordered 3 brand new replacement digitizers (from different sellers, all on Amazon), and all three power up but the touchscreen is completely unresponsive.

I suspect a software issue. I performed a update, but it didn't help (not sure if it hurt me).

Any ideas? Or some digitizers just obsolete after new Android updates? I read some chatter about these digitizer replacements faulty drivers.

Would really like to find a software solution before I forced to chip away broken glass to salvage original responsive touchscreen. TY!

Hi

Try restoring you phone to see if it’s a software issue as if it is it should go away after a restore

If that doesn’t work try taking the motherboard out and inspect for damage or discolouration as it could be a board related issue

I would pay close attention to where the screen and digitiser plugs in ,I would also give the connectors (both screen and board) a clean with some isopropyl alcohol and some cotton buds/Qtips as iv had screens act strangely and it was microscopic dirt I couldn’t see on the connectors

Hopefully this helps

Any questions please ask

Thanks:-)
