Xperia M which at present features android 4.1.2 version and Xperia M Dual features android 4.2.2 version, just now for both phones a major firmware is certified on PTCRB which seems as an upgrade to android version. Xperia M 15.4.A.0.21 firmware and Xperia M Dual 15.5.A.0.16 firmware is spotted on PTCRB besides some other firmwares which were certified a day before.

15.4.A.0.21 firmware is certified for Xperia M C1904 and C1905 which also saw 15.1.C.2.9 firmware and 15.1.C.2.8 firmware getting certified for it a day earlier. 15.5.A.0.16 firmware is certified for Xperia M Dual C2004 and C2005 which also saw 15.2.A.2.14 firmware getting certified a day earlier.

At present Xperia M is on 15.1.C.2.8 firmware which means a jump from 15.1.C.x.x to 15.4.A.x.xx firmware is huge update. Check below the 15.4.A.0.21 firmware certification for Xperia M on PTCRB page.

Rumors which these firmware certifications for Xperia M and Xperia M Dual has started that they might bring Android 4.3 update for them, though Sony didn’t mention about them in their android 4.3 update plan but a few days back we saw Vodafone Australia confirming that android 4.3 for Xperia M is in testing and it may come if everything goes right.

We hope if it is android 4.3 update anyhow, Sony should also roll it for Xperia L and Xperia C. Excited Xperia M and Xperia M Dual users, let us know. Drop your comments below.
