Sony Mobile is pushing a small firmware update for the Xperia M5, which moves the build number to 30.1.A.1.55 for the single SIM variants (E5603, E5606, E5653) and version 30.1.B.1.55 for the dual SIM variants (only E5633 and E5663 are live right now).
This is a small update from the previous version (30.1.X.1.46) and keeps the handset on Android 5.1 Lollipop. A number of owners have been suffering from a shutdown issue, so hopefully this update has provided a fix. If you’ve installed the update let us know your impressions in the comments below.
