Soft Reset - Samsung Galaxy Note® 3
Turning the device off and on is sometimes called a soft reset. This is similar to restarting a desktop computer and is often one of the first steps in troubleshooting a device. In most cases, a soft reset won't affect data on the device unless the battery is very low.
- Press and hold the Power button.
- Select Restart.
- Select OK.
If unable to perform a soft reset, remove then re-insert the battery.
