My iPhone 4S screen won't light up. When I receive a text it vibrates and makes a noise like usual, but the screen stays black. I've tried holding down the home and sleep buttons at the same time to turn it off and then back on, and I also plugged it into its charger, and nothing's changed.
Is there a way to fix this or is it broken for good?
