Sony Xperia C4 and C4 Dual get Android Marshmallow
Although Sony is no longer selling a significant number of smartphones, they continue to provide regular firmware updates to the units that were released so far. Now, the time has come for the Xperia C4 and the Xperia C4 Dual to get Android Marshmallow.
The models that get new firmware are E5303 & E5306 (Xperia C4), and E5333 & E5343 (Xperia C4 Dual). The firmware number 27.3.A.0.122 targets the C4, while the C4 Dual will be running the software version 27.3.B.0.122 after the update is complete. The features included are the usual Android 6.0 Marshmallow goodies - Google Now on Tap, Doze mode, Direct Share, granular app permissions, new emojis, next to the minor tweaks, fixes, and security patches that come with all such updates.
While the update should reach all these handsets worldwide, there is no official confirmation yet. The Xperia C5 Ultra could also get updated soon, but this has not been confirmed yet, either.
