Case A: In many cases, this procedure is done when we sell on the second hand or even give our device to a friend or family member so you can use, and do not want others to access our privacy information.
Case B: You may feel the performance of a Android device is slowing because of junk files that occupy the memory system, you Android phone often doesn’t work correct, poorly functioning.
No matter the reason, you should always format and reset the device. It’s necessary to let you understand that Android formatting means just deleting the user data i.e images, videos, songs, contact numbers, etc which you have saved in the phone memory. It will not touch the operating system. Formatting a Android brings the total loss of user information, not the system itself. Equivalent to formatting a PC, the system would remain intact, but completely clean customizations.
