Seemingly out of nowhere, Sony brought Android 5.1 to the Xperia C4 in mid-January and the company is at it again. This time, the Xperia M5 (30.1.A.1.33) and M5 Dual (30.1.B.1.33) are getting the bump.

The single SIM Xperia M5 (E5603, E5653, E5606) moves to build number 30.1.A.1.33, whilst the Xperia M5 Dual (E5633, E5663, E5643) moves to version 30.1.B.1.33. All of the variants, apart from E5643, are seeing the update roll at the time of writing.

This is likely further proof that Android 6.0 Marshmallow is indeed delayed internally at Sony – otherwise, why would they even bother with Lollipop updates?

Are any of your devices running Android 5.1?
