Digitizer (touch) not working after dropped
Well, the title is pretty self explanatory but I am going to expand a bit more to provide context.
My phone dropped (in its cover) flat on the ground (tiles). As soon as I picked it up, I noticed the phone restarted and I could see vertical strips in which the lcd was not working (all of it on the right hand side of the screen) and once it fully booted the digitizer was completely unresponsive. This was a massive problem as I couldn't back up my device
Ordered online a new lcd+digitizer to repair it myself and followed the steps provided here.
Once the panel was in place and the phone was closed, turned it on and tried to enter my pin. Digitizer is unresponsive... but for a moment it flicked... something was recognised as a swipe as it went from "locked screen" to "enter your pin". Noticed after a while that moving or squeezing the phone before pressing certain areas made it respond at times.
Did different orientations, squeezes and gentle taps and I managed to unlock the phone with extreme patience (so now I can backup my phone on my computer).
Disassembled the phone to tried the new panel on a working phone and it works without hassles.
What can be wrong with my phone? Has anybody had a problem like this?
EDIT 1: playing with the device I can notice corners react without issues so I can swipe up or down within certain range.
EDIT 2: if I use the middle of my thumb or two fingers it recognises swipe without issues and I can type with enough patience using the center of my thumb. I am starting to think the screen is dodgy. Anybody? comments?
