If a smartphone / tablet on OS Android for unknown reasons began to freeze or glitch, there is no need to rush to carry it to the master in the service center. There is not a small chance that you can solve your problem by performing a factory reset to Android. But only after completing it, all the settings will return to the factory settings, that is, by returning to the state in which you purchased the device, all data saved on the device's memory (applications, contacts, photos) will also be erased, and everything that is stored on your flash drive will remain untouched.

A full reset Android is advised to use if, for example, the tablet does not work stably, or the use has become not as comfortable as it was when buying. It can be done in several ways, which I will discuss below. It is recommended that you back up your most important data before performing a Reset.
