While i was charging, message popped to format the SD card now, options were cancel and not now, i preferred “not now” option. then suddenly the screen went blank and i could not recover for that. Although it shows the green light, yet the screen does not display at all. I hv googled and found that Xperia Z is encountering similar problems and as a solution described there, i pressed the off and volume buttons at the same time, the mobile vibrated for three times, and then it is as usual, it doesn’t display anything, neither does it show indicator now i would like to get further information regarding this issue, plz reply ASAP.
