Sony is planning to release the latest Marshmallow firmware to the company's select flagship Xperia Z series devices.

The company has confirmed the release of the new version of Android v6.0.1 mobile OS to Xperia Z3 and Xperia Z2 series in the coming weeks, Xperia Blog reported.

Sony also revealed that the 'Xperia Beta Program' has been closed permanently. It was launched in February in select regions to open communication between Sony device users and the software developers, so that company will be able to get feedback and iron out any glitches to improve the firmware before it is released to the public en masse.

There is no word on whether Sony has any plans of reopening 'Xperia Beta Program' as yet. But we believe the company will recommence it later this year after Google officially releases Android 7.0 Nougat around August and early September. 

Registered Xperia Beta Program users who had received the beta version of the new Android v6.0.1 in May, will also get the final firmware along with general public via OTA (Over-The-Air), the company said.

What's new in the latest Android v6.0.1 Marshmallow update?

Sony Xperia Z3 and Z2 series will get back the 'Stamina' battery saving mode, which was discontinued in the first Android 6.0 Marshmallow version, as it had Google's very own Doze power optimisation feature. In addition to that, it will also come with bug fixes and performance enhancing tweaks.

Official Change-log of the new Android M OS update:

  • New Stamina mode
  • New Ultra Stamina mode
  • Improvements on Bluetooth audio (issue with stuttering sound)
  • Memory handling improvements (multitasking included)
  • Various Wi-Fi connection improvements
