Side operating system: Comes with Android 2.3 (Gingerbred) that Mettera update "Over the Air" to version 4.0 (Ice Cream Sandwich). Android high performance, along with the entire contents of Market (Play Store). Very compatible for Google mail user, APS Google, Microsoft Exchange, POP, IMAP ... no worries to synchronize messages, contacts, calendar: it's simple and fast.
Listed weight, this phone is very light, plastic shell oblige: p If you want a phone that has the robust air, go your way.
Side autonomy it takes 2 days (Antenna, Wifi, 3G) with a few calls and Sync push email
I take off a star for the Samsung interface is not very ergonomic, but you can change to other "launchers" on Google Play Store!
Would recommend :)
