I have bought lumia 920 last year and recently there is problem in the display. Screen go all black. I have submitted my phone to Nokia care center and after all the hustle received another new replaced set. Within the 12 hrs there is again display problem in set and i have again submit that set. Its been more than a month i have been keep replacing my lumia phone. There is lack of testing in all the lumia phone. Earlier i having lumia 820 and i have faced the display problem in that set also. Nokia is losing its credibility and people in care center provides absolute nonsense as why there is problem in devices.
