in Firmware, Xperia M2

Xperia M2_D2303New 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.

    4.4.2 on T2 Ultra Dual = 19.1.C.0.117

    4.4.3 on T2 Ultra Dual = 19.1.1.C.0.56

    4.4.2 on M2 = 18.3.C.0.40

    4.4.3 on M2 = 18.3.1.C.0.21

    4.4.4 or 5.0 would be great, but I think Sony will release 4.4.3 for our device. Same number change :D

    Same here…. but it is very rare since the KitKat update.

    What you can do:
    – Disable/uninstall unnecessary apps
    – Use Greenify
    – Disable animations in Settings>Developer options

    Yes :) I had SP before this M2 :) SP story had bad finished

  • ShinOrochiX
