Tablet owners that are running Android 4.2 have the ability to take advantage of the all new multi-user feature, which allows for multiple user accounts on one device. To save people space, a developer has created Multi-User App Share, which allows for applications and their data to be shared between users, so no duplicate downloading and installing is needed. Root is required and the app, if used improperly, could potentially harm your device’s data if you accidentally misplace it. So, if you’re thinking about giving it a try, please use caution.
As another note, applications that use Market license checks could potentially not work as well, given there is another email tied to accounts. App Share is still in beta, so expect plenty of updates to come to improve functionality.
