Hey guys recently I noticed my iPhone showing a black screen, but the backlight is clearly on. I can also do standard actions like slide to unlock and stuff so the phone works, only the UI doesn't show. I did a hard reset, which worked but even during the reboot the problem was still there. After some time i can try again and with some luck the screen is back. This problem happens randomly. Is there anyone with a real solution? Restoring the device and configuring it as a new phone doesn't work either. Ideas?
