Hard Reset - advantages and disadvantages Vodafone 858 Smart?
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:
The ability to completely clear the phone from user information. Remove viruses and applications that slow down the phone and give constant errors. Solving problems that arose after installing some applications and remained after they were removed from the phone.
Disadvantages of Hard Reset:
All your contacts, data and media files will be deleted. The need to back up contacts and all user data. Not all viruses will be removed even after the hard reset procedure.
What needs to be done before the Hard Reset operation.
Before hard reset, make sure you know the access data for your google account, otherwise the phone will be blocked by the FRP. You can sign out of your google account before resetting. In this case, after performing a factory reset, you do not need to enter the login password for your Google account and you can immediately use your device. If, after a factory reset, the phone is locked because you cannot log into your Google account, then you need to find instructions for bypassing the FRP lock for your phone model. Not all owners of new phone models will be able to bypass the protection of the FRP and for this they will need to contact the official service center.
After performing a hard reset, your device will be completely wiped clean. Everything that was in the memory of your device will be deleted.
