Logged Z1 : Display does not turn on when on/off button is pressed
Hello you Z1-ers out there ! I recently have the problem that the logged display of my Z1 does not turn on when I push the on/off button on the right side of the phone. This happens after the phone got logged by pushing the same button before. When the display turned of automatically (i.e. due to inactivity) pushing the on/off button brings the display back to life though... But when I logged it myself then I just have the chance to press & hold the on/off button for about 10 sec - then it is coming up with the restart screen and I can get back to the display in operational mode. No idea where this problem comes from. A hard reset did not help - still the same issue aftewards. Thanks in advance to anyone out there who can shed some light on this mysterious problem !
