There are millions (if not billions) of Smartphones in the world , and more are produced everyday. This means that we have to constantly change Smartphones to ensure that we keep in touch with the latest mobile technology. In the process of frequently changing our Smartphones we lose a lot of apps that we love dearly , Android M is here to fix that!
Google has integrated Automatic App Backup system on Android M to ensure that you don’t lose your apps and their settings. This system automatically backup your phone apps to Google Drive every 24hours. The app data is automatically restored when the user changes or upgrades a device.
This feature is currently available to developers but we’re not sure if it will be available to users when Android M fully launches later this year.
