Quick Answer: To fix a flickering phone screen, force-restart your device and disable “Adaptive Brightness” in settings. If the issue persists, update your software or boot into Safe Mode. For screens with vertical lines or constant blinking after a drop, it is likely a hardware issue such as a loose internal cable or damaged LCD panel, which requires professional repair.
Imagine you are in the middle of an important call and suddenly, your screen starts blinking uncontrollably. If you are searching, “Why is my phone screen flickering?” you’ve come to the right place.
