Some parts of the screen on my Samsung Galaxy Tab phone are unresponsive. How can I resolve this issue?

Unresponsive areas on your Samsung Galaxy Tab phone's display can be disruptive. Troubleshooting these issues is crucial because they may have multiple causes:
• Screen attachments and accessories may reduce touchscreen responsiveness. This includes unofficial protective cases, stickers, and films. They can reduce touchscreen sensitivity and cause occasional recognition issues if not properly attached. Remove any extraneous items and try using the touchscreen again.
• Restarting your device can fix software issues that slow down its touchscreen. Reboot your Samsung Galaxy Tab to see if it fixes it.
• Charging issues can cause touchscreen issues. Check your device's charging and try a different charger or cable.
• Keeping your device's software updated fixes bugs and other issues. Install the latest software if you're having touchscreen issues.
• Increase device performance due to wear and tear. To maximize device performance, delete unnecessary apps, clear the cache, and leave enough space.
• In some cases, turning off touch sensitivity makes a touch screen more responsive. Check your device's settings for touch sensitivity adjustments.
• Restarting in Safe Mode can reveal if a third-party app is causing touchscreen issues. Offending apps may be deleted or disabled if Safe Mode works on the touchscreen.
• Have you tried everything else and nothing works? Back up your data and factory reset. This final attempt can permanently fix software issues.
