The Sony Xperia C4 and its dual-sim version were expected to get the update to Android 6.0 Marshmallow directly from its current 5.0 setup. However now, users are receiving an update to Android 5.1.
The update to Android 5.1 Lollipop is available now for both the Xperia C4 and C4 Dual in the form of build number 27.2.A.0.155 and 27.2.B.0.155 respectively. It also doesn’t look like an isolated event or an accidental update showing up on just a few devices.
The update is available across six different models of the C4 and C4 Dual and is available to download as an OTA (Over-the-air) update. We aren’t sure if this means that the C4 and C4 Dual won’t get the update to Android 6.0 or not. Only time will tell. It could possibly be just Sony releasing an update that brings some improvements to the performance, security etc. so that users will be happy while waiting for the next major update.
