Software Solutions:

• Reboot: A classic for a reason. Restarting your tablet clears temporary glitches and frees up memory, often resolving touch issues.
• Clean the screen: Dirt and grime can interfere with touch detection. Gently wipe the screen with a microfiber cloth and ensure your hands are clean too.
• Check for updates: Outdated software can cause touch problems. Install any available system or app updates to benefit from bug fixes and performance improvements.
• Calibrate the touchscreen: Over time, touch accuracy can drift. Most tablets have a built-in calibration tool in the settings. Run it to re-align the touch sensor with the display.
• Safe mode: This isolates essential apps and drivers. If your touchscreen works in safe mode, a rogue app might be causing the issue. Uninstall recently installed apps one by one to identify the culprit.

Hardware Concerns:

• Screen protector: Ensure it's properly aligned and not worn out. Replace it if necessary.
• Case pressure: Some cases can put pressure on the screen, affecting touch detection. Try using the tablet without the case to see if the issue persists.
• Physical damage: Cracks, water damage, or drops can damage the touchscreen hardware. If you suspect physical damage, consult a professional for repair.
