Reset Device

A normal reset is sometimes referred to as a soft reset. A normal reset stops all running applications but does not erase any programs or saved data.

Caution be sure to save any unsaved data before performing a normal reset since a normal reset erases all unsaved data.

To perform a soft reset:

If your device is frozen and unresponsive, press and hold for 8-10 seconds. The device will reboot automatically. 

 

A full reset is sometimes referred to as a hard reset. Perform a full reset when you want to clear all settings, programs and data from RAM. A full reset deactivates the battery the power button does not function until the battery is reactivated.

Caution if you perform a full reset, your Samsung Mini GT-S5570 returns to its default settings and looses all information that is not recorded in ROM.

To perform a hard reset:

In Idle mode, open the application list and select Settings > Privacy > Factory data reset > Reset phone > Erase everything.
To perform a hard reset using the buttons:
