New Android M beta with Stamina mode coming to Sony Xperia Z2, Z3 series next week: Report

It's been close to one month since Sony released the public version of Android Marshmallow to Xperia Z2 and Z3 series phones. Now, the company is reportedly planning to roll out a new update with new features to the aforementioned devices.

To make sure the new Android M update is clean and bug-free, Sony will release the beta version first to registered "Xperia Beta Program" owners of Xperia Z2 (D6503), Z3 (D6603) and Z3 Compact (D5803) next week. If satisfied with the feedback, the company will deploy it to public en masse, probably by this month-end or early June.

Interested users who wish to get 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]
