I have a z3 compact and was having problems with the touch screen so I fitted a new screen with no problems but new screen wouldn't turn on but could hear text coming in, so put old screen back on and that was same!!
Problem I have now I've lost all everything on my phone as I have a password on phone and I can't back up on pc because I need to put password in to back up 😲
In hindsight I should have backed up 1st but I didn't So is there any way I can back this phone up or fix screen problem ☠
