Sony Mobile is rolling out a new firmware update for the Xperia L (C210X) in the form of build version 15.0.A.2.17. One of the notable features it introduces to the handset is Small Apps, which thus far had been absent. Users are also reporting performance enhancements and big fixes. The update appears to be out in Indonesia and is likely to roll out to other regions soon.
