The latest updated released for School Life on Android devices is in the Google Play store now.
This updated fixes minor bug and improves general performance and also adds a new feature: Mute Notifications
Unlike Apple devices, where you can manage the notifications from the device itself, the School Life Android application has been upgraded with an option so you can mute the notifications from within the application.
This can be found under Menu (top right) then select Preferences. For more help please see the How To section.
