A Soft Reset (or Forced Restart) differs from a Hard Reset (or Factory Restore) in that it doesn’t delete any essential data from the smartphone or tablet but you may lose some RAM or temporary data, for example any unsaved game progress or the page you were viewing on a website.
A Hard Reset on the other hand would only be required when you want to wipe all data from the device, starting it over.
1. Unlock your screen and then find power button and hold it down.
2. The menu should show up on your screen
3. Choose Restart or Reboot option from the menu.
4. Now your phone will restart and the soft reset is over.
