Hard Reset - Reboot the device, during which the factory settings of the system are restored and all user information is deleted, including installed programs, contacts and SMS.

Hard Reset in the smartphone will save him from some problems, but, alas, will not save in the event of a serious breakdown. Use this simple way to get rid of files downloaded to the phone's internal memory, recall a forgotten graphic key, speed up the device a little, or make it turn on again.

Hard Reset will also help prepare your smartphone for sale or exchange in an electronics store according to the trade-in scheme.
