You may have heard talk of the experimental and unannounced multi-account feature in Android 4.1 that allows you to create multiple profiles on a device. In a nutshell it allows you to use your mobile device in a manner similar to how you are able to use a PC, where separate user profiles can be created. This makes it perfect for a household where multiple people may use a tablet on a daily basis, or simply creating a profile which allows others to use your phone without accessing certain apps like social networks and messaging.
This semi-hidden feature is enabled via the terminal emulator application, once a new account is created, it becomes available via the devices power menu. It’s pretty simple stuff. However XDA Forum Member Raghav Sood has taken it upon himself to make this feature more user friendly by creating a GUI that allows you to manage these accounts without the use of the terminal. It performs simple operations such as creating, renaming, and deleting users; viewing all current profiles; and of course, switching between them. The developer also explains what the relevant terminal commands are if you prefer to do things the long way.
It’s important to remember that this new function is far from finished, and there wills be bugs. However, it does look quite promising. If you would like to try this out for yourself then check out the original thread.___________________
