So I was updating my apps and suddenly my phone freezes and eventually went blackout. After these things the phone now won't open. I tried charging it but it wont respond. I tried to press the power button + lower volume button + lit the light sensor but it's no use. please anyone help me

Do you have USB debugging turned on? Plug it in your computer and try adb reboot (assuming you have ADB).

Hi, Thanks again for the reply. I installed adb reboot. but the sad thing is.... i don't think I've set the USB debug on
