Sony Mobile has released the Android 6.0.1 Marshmallow update for the Xperia Z3 and Z3 Compact handsets running the Concept for Android beta trial. Build number MMB29M.Z1.3021-somc moves the Android version to MR1 (Maintenance Release 1). The only change we are aware of (apart from the update to Android 6.0.1) is that Sony has now removed the Icon pack found within the Home settings. The “Icon appearance” is still there, but Sony has removed the three options that it included previously. This latest update should be rolling to all Sony Concept for Android Marshmallow owners via OTA right now.
Thanks Adrian, KubsiJack, Marcus and Timo!
