As promised, Sony has rolled out the new Android 6.0.1 Marshmallow beta to Xperia Z3 and Z2 series phones.

The new update is released only to the registered "Xperia Beta Program" owners of Xperia Z2 (D6503), Z3 (D6603) and Z3 Compact (D5803), Xperia Blog reported.

A key aspect of the new beta firmware is the return of the Sony's proprietary battery-saving Stamina Mode option, which was discontinued in the first Android Marshmallow version. The former came with the Google's own Doze power-optimisation feature.

"Stamina under Lollipop had a completely different configuration due to the operating system itself. What we can do is improve the new Stamina in other ways, including usability, functionality, stability, reach etc., but always within the new OS framework," a Sony software developer team member said in statement.

The new firmware also fixes the Wi-Fi connection bug, the Bluetooth audio glitch and other issues.

Based on the feedback, the company will release a final version to the public en masse, probably by end-May or early June.

Interested users who wish to be enrolled for the soak test need to download Sony's "Xperia Beta Program" on Google Play Store (HERE). [Note: This application is available in select regions only]
