This phone comes up with 4.3 jelly bean but what I liked about this phone this can be up gradable to 5.1.1 lollipop officially by the sony which is great thing about this phone ohh sorry fablet . This upgrade is very good from sony for this mobile because for all other mobile that are launched with t2 ultra like samsung note 3 neo did n, t get this update.
But the thing that I did’nt liked about this phone is that the internal memory is only 8GB which after giving to android OS only approx 4GB available to the user for the apps. Except from this the main feature of this phone is very good like:
Good battery life having 3000mah
A massive 6 inch screen
Good air effect in camera
Dual standby feature
