Hello I bought Xperia T over a week ago and I updated it to the latest firmware, I first experienced this problem as the heading says then I just had to connect it to the charger but yesterday it happened again I tried like I did last time but nothing happened I could hear the phone ring and the camera opening but the screen is completely black.
I tried to hold down the power and volume up lockers and I could feel the phone rebooting but the screen doesn't come to life it's still black and I've tried to waiting for some hours but upto now there's no change.
Please help I truly appreciate your time and consideration.
