Every now and then, your Samsung Galaxy Tab 2 might lock up and become unresponsive. These devices aren’t perfect after all, and are prone to lock up from time to time.
If you just need to force the tablet to restart (also known as a soft reset), then do the following:
To force the tablet to restart, simply hold the power button down for around ten seconds or more. This will force the tablet to shut down, allowing you to power it back up again.
If this doesn’t work and you’re still having issues with your tablet locking up, then you may need to perform a hard reset on the device.
This process should work for both the 7 inch model (version 7.0) and the ten inch model (version 10.1) of the Samsung Galaxy Tab 2.
