Sony Mobile has released a new Concept Marshmallow release with build number MOB30G.Z1.3606. The Android 6.0.1 update includes the latest June 2016 Google security patches. Sony has also fixed an issue that some people had reading files with large SD cards. Other bugs that have been ironed out include a data connection retry problem, a Bluetooth restart fix issue as well as bug fixes for the Xperia Tips and InTouch apps. The update went live a few days back, so most people running Concept firmware should have received the new firmware by now.
