Its hardware problem.
Bad contacts in LCD signal lines. Check connections PCB->Keyboard and Keyboard->LCD

Best regards

We had where about 10..15 phones with same problem. Most of them was absolutly new (just from package).
Most of them was repaired in next way:

Under LCD contact rubber placed plastic film with contacts. We clean this rubber and contacts on film.
After this we put small piece of paper folded in 2..4 layers under film, assemble phone and test it.
BE VERY CAREFULL! Dont crash LCD!

For better understanding:

##########
########## - LCD CONTACT RUBBER
=========== - Plastic film with contacts
<><><><><>< - Piece of paper
//////////////////// - Phone board

As I remeber 1 phone was with simply damages keypad plastic film

Was repaired only by keypad plastic film replace.

Generally that, a reason of hangup are the disturbances and absence of the answer in I2C bus (no answer from LCD)

Best regards
