What happens when you reset your Android to its default factory settings?
A factory reset, also called a hard or a master reset, can fix some of your Android's issues and improve its overall operation. If Android lags or apps keep crashing, factory resetting it might be a good last-resort type of solution. Whenever an Android device changes hands, it is also recommended to reset it to its default factory settings and start with a clean operating system.
When you perform a factory reset:
- All the data and apps found on your Android smartphone or tablet are wiped. This includes both system and downloaded apps, as well as personal files like the pictures you took with the device and the music you stored on it.
- All the user accounts found on your Android smartphone or tablet are deleted.
- All your Android device's settings are restored to their defaults.
- Your Android operating system is reset.
The result of a factory reset is a device that acts as new from a software, settings, and data perspective. When you start an Android device that was reset to its default factory settings, you are taken to the configuration wizard, where you get to configure the device anew. You should perform this reset any time you wish to give your Android device away, to ensure others don't get access to your user accounts, personal data, files, and apps.
