Troubleshoot touchscreen issues on a Samsung Galaxy device

A temporary system error may cause the touchscreen to stop responding normally. Restart your Galaxy device and check again.
 

Press and hold the Side key and Volume down key at the same time for more than 7 seconds until the device restarts automatically.

Screen protectors, cases, or other accessories attached to the device may affect touch sensitivity and gesture recognition.

Increase touch sensitivity
 

If a screen protector or tempered glass is attached, try increasing the Touch sensitivity setting.

1. Open Settings, then tap Display.
2. Turn on Touch sensitivity.
   

Remove non-genuine accessories
 

Non-genuine screen protectors or cases may affect touchscreen functionality or cause gesture recognition issues, especially around the screen edges.

Remove the screen protector or case and check whether the touchscreen works normally.

Note: Non-genuine accessories may affect touchscreen performance and device functionality.

Check your charger

If your charger is damaged, it may not supply power to your device, which may cause the touch screen to malfunction. In this case, use a different, undamaged charger to prevent this issue. It’s also a good idea to avoid using the touchscreen when the device is charging.

Certain accessibility settings may affect touch response or screen behavior.

Turn off TalkBack

If voice guidance plays when touching the screen and touch gestures do not work normally, the TalkBack feature may be enabled.

• Tap once to select, double-tap to open.
  
• Touch and drag with two fingers.
  

Follow the steps below:

1. Open Settings, then tap Accessibility.
2. Tap TalkBack.
3. Tap the switch to turn off TalkBack.
   

Check Touch settings

If the touch and hold delay, tap duration, or ignore repeated touches settings were changed unintentionally, restore them to the default values.

1. Open Settings, then tap Accessibility.
2. Tap Interaction and dexterity.
3. Set your desired touch settings.
   

Check Magnification shortcut settings

If the Magnification shortcut is set to triple-tap on the screen, quick touches may be missed, or touch response may become slower.

1. Open Settings, then tap Accessibility.
2. Tap Vision enhancements.
3. Tap Magnification.
4. Tap the switch to turn off Magnification shortcut.
   
5. Or change the Magnification shortcut settings.
   

When using the full screen gesture function, touch input may not be possible because the touch is recognized as a gesture. To stop this from happening, disable the full screen gesture function.
 

1. Open Settings, and then tap Display.
2. Tap Navigation bar, and then tap Buttons.
3. Disable full screen gestures.

Moisture or water on the screen may affect normal touchscreen operation.

Wipe the screen with a soft, dry cloth and try using the device again.

Outdated software or apps may cause compatibility issues or abnormal display behavior. Make sure your device software and apps are updated to the latest version.

Check for software updates
 

1. Open Settings, then tap Software Update, and then tap Check for updates.
   
   
2. Follow the on-screen instructions. A confirmation will appear once the software is up to date.
   
   

1. Open the Google Play Store app, then select your Google account.
   
   
2. Tap Manage apps & device to check for available updates, and then tap Update all.
   

If the issue continues after trying the steps above, use Samsung Members Phone diagnostics to check the touchscreen status.
 

1. Open the Samsung Members app, then tap Support.
   
2. Tap Get started. The full diagnostics scan will begin. You can stop the process and select specific items to run individual tests.
3. Select Touch screen.
   
4. Follow the on-screen instructions and check the diagnostic results.

Safe mode will help determine if there is a recent third-party app that is causing an issue on your device.

1. Press and hold the Power button (or Side button) and the Volume down button at the same time. You can also swipe down from the top of the screen using two fingers, and then tap the Power icon.
   
2. Touch and hold Power off, and then tap Safe mode.
   
   
3. Once you're in Safe mode, you can remove third-party apps. Start by removing apps that were updated or installed when the problem started.
4. To exit Safe mode, simply restart your phone or tablet and it will reboot normally.

Resetting your device to factory defaults should only be used as a last resort and after trying the previous steps. A factory data reset will remove all data and content from your device. Before performing a factory reset, be sure to back up your personal data, so you don't lose it all.
 

1. Navigate to and open Settings, then tap General management.
   
2. Tap Reset, and then tap Factory data reset.
3. Swipe to and tap Reset, and then tap Delete all.
4. Enter your Samsung account credentials to complete the reset; your device will reset, and you will need to perform the initial setup process.
