Hello, I have had a Sony Xperia Z2 for 2,5 years now and it has been working smoothly without any troubles. Recently my wife's old Samsung Galaxy S2 died so she bought a used Xperia Z2 as well from a guy here in Cyprus. The phone seemed intact, no scratches, dents etc. I reset her phone to factory settings and updated to Android 6.0.1, before she starts using the phone. Everyhting seemed to work properly but after 2-3 days the screen started not responding. When pushing the power button to switch on the screen the screen simply remained black. But the phone was on. I noticed that if I insisted and pressed hard at some low part of the screen then the screen might have responded and switch on but then would immediately go black again before having the chance to use the phone. Sometimes it stays on and I can use the phone. I have tried everything, (glove mode is off), I even reset the phone back to factory settings and worked with Android 5.1 (Lollipop) but the same issue was there (so I think its a hardware problem). If anyone could help it would be much appreciated.
