Sony has just released the Android Version 6.0.1 (Marshmallow) update for the Sony Xperia C5 Ultra.
Right now, the marshmallow update is hitting the phone’s dual variant (having a model number E5533) in Italy and will come with a firmware number of 29.2.B.0.122.
Just like any other Over-the-air (OTA) roll out, the update will be sent wirelessly and it might take a little time for the marshmallow update to hit your own device.
Well, if you feel impatient or you’re pretty too anxious, you can manually go to your phone’s settings menu and check for the update.
