Experiencing an unresponsive touch screen on your Samsung Galaxy M15 can be a frustrating issue that significantly hinders your ability to use your smartphone effectively. Below, we detail each step to help you regain the functionality of your device’s touch screen.
Steps to Resolve Samsung Galaxy M15 Unresponsive touch screen
1. Restart Your Device:
Restarting your device is a fundamental troubleshooting step that can resolve many minor software glitches. This action refreshes the system’s processes, potentially fixing any temporary bugs affecting the touch screen. Press and hold the Power button until the power off menu is displayed, then choose Restart.
If the touch screen is completely unresponsive, you can perform a forced restart. This is done by pressing and holding both the Power button and the Volume down button simultaneously for approximately 10 seconds. This forced action can bypass the standard shutdown process, helping to reset any software issues.
2. Check for Physical and Liquid Damage:
Physical or liquid damage to your smartphone can directly affect the touch screen’s functionality. Such damage may not always be immediately visible. Carefully inspect your Samsung Galaxy M15 for any signs of damage. Look for cracks, dents, or signs of liquid entry. In cases of physical damage, the touch screen’s hardware may be compromised, necessitating professional repair. If liquid damage is suspected, it’s crucial to power off the device immediately to avoid further damage and consult a professional repair service as soon as possible.
3. Remove Screen Protector and Cases:
Screen protectors or cases can sometimes interfere with the sensitivity of the touch screen. This interference might be due to improper installation or the accumulation of dirt and moisture beneath them. Gently remove any screen protector or case from your device. After removal, test the touch screen’s responsiveness. This can help you determine if these accessories were affecting the screen’s sensitivity.
4. Test the Touch Screen in Safe Mode:
Booting in Safe Mode is a diagnostic tool. It disables all third-party apps temporarily, which helps identify if the issue arise from an app you installed. Press and hold the Power button, then press and hold on the Power off option that appears on the screen. Select Safe Mode when prompted. If the touch screen functions correctly in Safe Mode, it indicates a third-party app is likely causing the issue. You can then uninstall recently installed apps one by one to find the problematic app.
5. Clean the Touch Screen:
A clean touch screen is essential for optimal functionality. Dirt, grime, or moisture on the screen can affect touch sensitivity. Use a soft, lint-free cloth to gently clean the screen. It’s important to avoid using water or other cleaning fluids directly on the device to prevent damage.
9. Seek Professional Help:
If after following the above steps, the touch screen remains unresponsive, the issue might be hardware-related, necessitating professional diagnosis and repair. Call Samsung support or visit a Samsung service center. Professional technicians can diagnose hardware issues like a faulty touch screen digitizer or connection problems and provide the necessary repairs.
Conclusion
Troubleshooting an unresponsive touch screen on your Samsung Galaxy M15 involves both simple and more complex steps. Through this process, it’s possible to identify and resolve the underlying cause of the touch screen problem.
