Iphone will not turn on
This am my iPhone 7 suddenly went black when posting to Instagram. I have tried charging it with tow different charging cables, and also attempted a back up battery and my computer... still black, won't turn on.

Made an appointment for the apple genius bar... but would love a faster remedy.
