Samsung Galaxy A21 - Reset All Settings

If your Galaxy A21 crashes, resets or runs slowly, or apps freeze or cause the device to reset, view this info.
Restoring your device to default settings helps when the device crashes and resets itself or when apps freeze / hang or reset the device.
Performing these steps resets all system settings (e.g. ringtones, sound settings, display settings, etc.) back to their default values. Personal data, such as downloaded apps and media (pictures, videos, music), aren't affected; however, the device automatically restarts to apply any changes.
  1. From a Home screen, swipe up from the center of the display to access the apps screen.
    These instructions only apply to the default Home screen layout.

    Settings Settings icon
    General management
    Reset
    .
  3. Tap
    Reset all settings
    .

    Reset settings
    .
