It has been happening since the beginning but in last 3 days I had to reboot 5-6 times.......... Basically what happens is that display stops working even if a call comes or even if i try home key or anything else.......... Phone function work fine (like ringer volume up or down can be done)............. But touch screen function doesn't work and screen doesn't light up ......... So i have to reboot to make it display working again.............. Display is just fine though and looks like a driver kind of issue 😕 any solutions?????
