2.Recently used apps finding made easy
3.Network data consumption alert
5.Change of names of Sony apps like music, video to walkman, movies and addition of notes.
6.Developer options in settings
Bottom Line :
Though few essential updates are made like network data usage alert , chrome browser , glove mode the look and feel of Sola remains more or less the same which can be said either as a plus or as a negative if you are not a Sony fan. A special kudos to Sony team for bringing in the update for a second set of smart phone devices , which are neither their flagship models , nor a real competition for S3 or iphone. Hope they will bring 4.1 or 4.2 update real soon.
