A network carrier has reportedly confirmed that select Sony Xperia Z series device will get the MR1 (Maintenance Release) aka v5.1 Lollipop in a few months.

Before Sony could finish the phase-1 Android 5.0 Lollipop roll-out process for entire Xperia Z series devices, Telstra, Australia's biggest network provider has confirmed that Xperia Z, Z1 and Z1 Compact will get the new v5.1 update later this year on 10 August 2015.

But, we like to advise our readers not to keep high hopes on this report because there is possibility that the company might change the release schedule. On 1 May, the company received a memo that the test software to Google for approval has been found to be having a 'showstopper' bug.

Telstra has confirmed that it will fix the bug and once again re-submit test software to Google on 10 July. As of now, there is no word on when Android 5.1 Lollipop will be deployed to other Xperia Z series devices. We will update on this as it develops.

To recap, the new v5.1 firmware is a very important update of the Android Lollipop OS series as it is said to fix some of the most nagging bugs such as, Wi-Fi tethering issue, Bluetooth connectivity, CPU wake-locks, which result in heavy draining of battery, Chrome crash during launch, deletion of SMSs when SIM memory gets exhausted and many more.
