Still Deciding?
Fix a Problem
What should you do when a phone screen flickers or goes black?
A flickering or black phone screen can result from a frozen app, low power, software, or damaged hardware. Start with safe checks before resetting or repairing.
What to do
- Try the manufacturer's force-restart steps.
- Check charging with a known-good cable and outlet.
- If the phone rings but the screen stays black, arrange professional evaluation.

Check this before relying on the answer
