Hard Reset - advantages and disadvantages Sony Xperia Z5 Compact E5823?
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 have arisen due to the conflict of some applications and those remaining after they were removed from the phone.
Disadvantages of Hard Reset:
Complete cleaning of all user data on the device. The need to have an up-to-date backup of your data, contacts, settings and media files. 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. Then you do not need to enter the login password to your Google account and you can immediately use your device. If, after a hard reset, the phone is locked by the FRP and you cannot remember the login password for logging into your Google account, then you need to use the instructions for bypassing the FRP lock for your phone model. You will need to contact the official service center to bypass the FRP protection on some new phone models.
