Sony Mobile has started to roll minor updates for the Xperia M2 (D230X). This includes the LTE model (D2303) which is currently seeing build number 18.3.1.C.1.15 roll (from version 18.3.1.C.1.13 previously). The update is live across a number of regions including Germany, Nordic, Italy, Portugal, Middle East, Singapore and Philippines. At time of writing, the update has not landed on the D2306 LTE model nor on the Xperia M2 Aqua variants. [Update: It is now live for the Xperia M2 Aqua]
The Xperia M2 Dual (D2302) has seen build number 18.3.1.B.1.10 roll (from version 18.3.1.B.1.8 previously), but it is currently only out in Singapore. Whilst, the HSPA+ Xperia M2 (D2305) has seen build number 18.3.1.A.1.9 roll (from version 18.3.1.A.1.7 previously) in Argentina, Latin America, Singapore, US and Vietnam.
