Save previous APK before an update
From Anonyme
Sometimes, an update breaks an application and we have to wait for another update. So in order to avoid that, Apps should save the APK of the local application before update it. In case the update breaks the app, the user would just have to press a “Restore to the previous version” button. (Maybe it’s not possible to downgrade an application without deleting it. But at least the user would have the possibility to delete and re-install an application to its previous version if this is a necessary.)
