If you’re experiencing problems with your Samsung Galaxy Tab 10.1, you may want to try to soft or hard reset the device using these methods.
If the device is frozen or unresponsive, try pressing and holding the Power button for about 10 seconds. This should force the Galaxy Tab 10.1 to restart normally.
A hard reset will set the device back to factory default settings and erase all data on the device. This is normally done when troubleshooting methods prove to be fruitless.
1. From the Home screen, select Apps in the upper-right corner.
2. Choose Settings.
3. Select Privacy.
4. Select Factory data reset.
5. Select Reset tablet.
6. Select Erase everything.
