S7: How do I force to reboot or restart when the screen is frozen or device is locked ?
Restart your device
In the unlikely event that your device becomes unresponsive, you can attempt a force restart. This will turn your device off and back on without affecting any data stored on the device.
Important : Do not attempt to remove the battery from your device. Doing so may damage the device and battery and could cause burning and injury.
Note: Screens and settings available may vary by wireless service provider and software version.
Force Restart
To force restart your device, press and hold the Volume down key and Power/Lock key on the device for 10–20 seconds. This performs a simulated battery disconnect.
Note: Ensure your device is charged to a minimum of 5%. If your battery is below 5%, the device may not turn on after the restart. A device that is completely drained should be charged for a minimum of 15 minutes using the wall charger supplied with your device
