My iPhone is turned on but the screen is gray
I turn on my phone and i know it is on because of the silent switch it vibrates. But when i turn my phone on all the screen does is turn gray i have turned the phone on and off 5 times now and it does nothing. The screen emits light but the screen stays Gray
Is this a good question?
Try a hard reset, hold power and home button for 10 seconds. If that doesn't work try a DFU restore (Google DFU restore for the steps). If no luck there then you may have to follow Buddhika's recommendation.
