When a phone’s screen stops responding to touch, the cause could range from simple software glitches to more serious hardware issues. Begin by restarting your phone, as this can often resolve temporary software freezes. If the screen is still unresponsive, make sure your hands and the screen are clean and free of moisture, as dirt or moisture can disrupt the touch sensitivity. If you’re using a screen protector, consider removing it, as some protectors can interfere with touch response. For issues related to software, starting your phone in Safe Mode (available on most smartphones) can help determine if a third-party app is causing the problem. If the screen responds in Safe Mode, an app is likely responsible, and uninstalling recent downloads could resolve the issue. For persistent problems, it may be necessary to perform a factory reset. If none of these solutions work, it’s possible there’s a hardware fault, and a professional repair may be required.
