It’s a good idea to keep your Mobile Zone and Zone Manager App up to date on your family’s devices.

Simply 

  1. Grab the device and unlock the screen

  2. Open the Google Play Store

  3. Tap the menu (三) in the top left of the search bar

  4. Select My apps & games

  5. Select Update all or Update next to the Mobile Zone or Zone Manager App

If there are no updates available, it generally means that you have the latest version already.
