When digging around the Android Open Source Project, Android Police writer Ron Amadeo discovered that Android 4.1 Jelly Bean already contains the necessary code to support multiple users.
The XDA developers also discovered the feature, with 'zanderman112' shooting a video on how to enable the function on a forum post.
This code reportedly allows users to set different lock screens, home-screen layouts and available apps, with all of this information being stored in a “users” directory. Users are labelled as ‘User 0’, although presumably renaming folders will be allowed in future.
Google officially refused to comment on the news, although Google engineer Amith Yamasani did hint that work is on-going by saying that the feature is "not ready for deployment" when responding to one developer.
Multi-user accounts would certainly have a significant impact on how Android smartphones and tablets are used business and education. These accounts would allow businesses to embrace bring-your-own-device (BYOD) schemes, while setting separate settings for work and personal data.
