There are a number of reasons why Android smartphone users need to reset their device to factory settings. It could be because there are too many applications so that performance slows down, or users download the latest updates but instead some of the device functions have problems.
The most common reason for resetting the device to factory settings is when selling a smartphone. Of course so that the privacy stored in the device can be safe from the new owner.
Important : Before you start resetting, you should know that doing a factory reset will delete all Android phone data. For that, you should back up all your data such as contacts, documents, photos and other media files.
