Hard Reset - advantages and disadvantages Samsung i640?

In simple words, Hard Reset means hard resetting the phone. As a result, the system automatically returns to the factory settings and the system is completely cleared. Contacts, correspondence, application, files, search queries, passwords - all of this is deleted from the device's memory.

Benefits of Hard Reset:

Removing viruses that have entered your phone.
