New firmware certified for Xperia M2 (18.3.1.C.0.21 and 18.3.1.A.0.21) and Xperia M2 Dual (18.3.1.B.0.18)

New software builds have been certified by the PTCRB for the Xperia M2, Xperia M2 Aqua and Xperia M2 Dual. The LTE versions of the Xperia M2 and Xperia M2 Aqua have seen build number 18.3.1.C.0.21 certified (versus 18.3.C.0.40 currently), whilst the HSPA+ Xperia M2 (D2305) has seen build number 18.3.1.A.0.21 certified (versus 18.3.A.0.31 currently).

The Xperia M2 Dual has seen build number 18.3.1.B.0.18 certified (versus 18.3.B.0.32 currently). Judging by the change in build number, there is a good chance that these new firmware builds bring Android 4.4.3 or even Android 4.4.4 to these handsets. We’ll confirm once the software starts rolling.
