A friend of mine had a cracked display on her galaxy A5 2017. She was on holidays and got it fixed there in a repair shop. But now the phone started to crash randomly. It goes like this:
* Turn phone on
* unlock sim and phone —> display works fine
* lock phone —> screen turns off (as it should)
* press home or lock button to unlock again —> two possible outcomes:
## display turns on, ready to unlock, everything works fine
## phone crashes, flashes some orange lines across screen and flashes the soft buttons (the ones left and right of the home button) and restarts
I have already opened the phone up but could not see anything wrong. We also noticed that the blue light filter does not work anymore with the new display.
What can I do to try and fix it? Should i just buy a new display or will that not work?
