How do I check if there is an Android 6.0 (Marshmallow) update available for Xperia M4 Aqua
The only way to find out if there is an available Android 6.0 (Marshmallow) update for your Xperia™ M4 Aqua or Xperia™ M4 Aqua Dual is to connect your device to a computer running the Xperia™ Companion application.
There will be no notification in your Xperia™ device announcing the Android 6.0 update. Nor will there be an indication in the Software update app under Settings > About phone > Software update that an Android 6.0 update is available.
- Download the Xperia™ Companion application to your computer from https://support.sonymobile.com/global-en/xperia-companion/.
