Android 4.2 comes with multi-user support and new keyboard with word completion
The launch of the new devices Nexus 4 and Nexus 10 also came with a new version of its Android operating system 4.2. “A new flavor of Jelly Bean” as is promoted by Google.
Perhaps most interesting is that Miracast bring support for a new protocol for streaming music and video that is powered by Intel and already has the support of the industry of television manufacturers. That is, the system would take your wireless phone as a media player (and could even be used as a separate screen for complex games, developers say Google).
Android 4.2 also includes a new type of writing with gesture-based keyboard similar to Swype , but the words showing up when you slide your finger across the keyboard. It is a feature that complements quite well with SwiftKey, the Google tool that predicts the next word you write.
Another feature that has Android 4.2 is having a support for multiple users, which greatly facilitate shared use of a tablet, for each profile settings and logs stored separately from the device applications. That is, the Angry Birds will score for each individual user, not the device.
