FAQ
Why is my screen flickering?
Screen flickering is often caused by apps, display settings, or hardware issues. Try disabling auto-brightness, updating apps, or performing a soft reset.
How do I fix dead pixels?
Dead pixels cannot be fixed by software. Try using display repair apps as a temporary solution, but hardware replacement may be necessary if many pixels are affected.
Is screen burn-in permanent?
Screen burn-in may be temporary or permanent depending on severity. Disable static content, reduce brightness, and enable screen rotation to prevent further burn-in.
Why is my screen not responding to touch?
Clean the screen with a soft cloth, restart the device, disable screen protectors if they're interfering, and check if the touchscreen is locked in settings.
