Troubleshooting

The touch screen responds slowly or improperly

•If you are wearing gloves, if your hands are not clean while touching the touch screen, or if you tap the screen with sharp objects or your fingertips, the touch screen may malfunction.

•The touch screen may malfunction in humid conditions or when exposed to water.

•Restart your device to clear any temporary software bugs.

If the problem is still not resolved, contact a Samsung Service Centre.
