I just want to share my experience with my xperia z1. I bought it last 4 days. On the first day, the phone screen was totally jammed, cannot press anything, even cannot to be switched off. I leave the phone until the battery totally empty.
On the second day, once the battery totally empty, i tried to charge the phone but still cannot. Finally, i press volume up+switch on button, the phone vibrate and can be on. I leave the phone for charging until the battery full. When i started use the phone, the battery dropped too fast. Within only 30 minutes, the battery drains about 50%. I have no option but have to bring together my power bank everywhere i carried my phone.
Third day, i face problem where suddently, my z1 cannot detect sd card although on last two days it was working fine in my phone. I tried to off and take out the sd card, and on back the phone but still the phone unable to read sd card. Finally, i format the sd card and lost all the files.
'Thank you' sony for these experience.
