I ordered an Xperia Z Ultra and received it in the mail yesterday. Unfortunately, the unit I received has a defective screen. When you press the power button, the screen backlight turns on but stays completely blank (black). Android is still running fine underneath -- pressing back/home/app softkeys gives haptic/audio feedback, pressing volume rocker gives volume up/down sounds, etc. However the screen stays completely blank and the device is unusable.
No matter how many times you press the power button, the screen still remains blank/black. The screen will only turn on correctly, randomly. On my unit, anywhere between 5 and 150 power button presses.
The screen also has a noticable yellow tinge.
Turning-off the phone first does not solve the problem. In fact, the screen is still blank when booting up (i.e.: the "Sony/Xperia" loading screen/boot animation).
Pressing the hard-off button next to the SIM card tray also does not solve the problem.
Pressing and holding Power+VolUp also does not solve the problem.
Factory-resetting via Settings also does not solve the problem.
Reflashing latest firmware from PC Companion or SUS also does not solve the problem. (Flashes correctly, but screen is still defective)
So just beware, for anyone getting a C6802. Either confirm in-person that you don't have a defective unit, or have your retailor confirm for you.
The unit I received:
- C6802 (3G-only), White
- Hong Kong, unbranded
- Manufature date: 13W29 (2013, Week 29)
- Firmware version: 14.1.B.0.471
