The local service has informed me that they are not able to repair my phone in time (we have legislation limits on the terms of warranty repairs) and seller has refunded me the cost of my phone.
I think I should say thanks to @Irene2_ASUS
for such fast decision.
So I have crossed the fingers and bought Zenfone 8 (16/256) again.
I hope that the shell will not hit the same place in the third time 😊
