Sony's flagship Xperia Z Ultra GPe (Google Play edition) has begun receiving the new Android v5.1 Lollipop notifications.

Technology blog Android Central has confirmed that the Google has begun rolling out the new v5.1 Lollipop (build number: LMY47D) to the Sony phablet Xperia Z Ultra GPe in the US.

The new firmware v5.1 is 212MB in size and it is not a major update, but rather a bug-fixing software patch. We believe these very enhancements will be reflected on Sony device as well.

How to Install Android 5.1 Lollipop update on Sony Xperia Z Ultra GPe via OTA [Over-The-Air]:

If Sony Xperia Z Ultra GPe series owners are getting the update notifications, then select - "Yes, I'm in" option >> then, after downloading, select >> "Install now." The phone will restart automatically and the OS will be updated to the new version.

We would like to remind out readers that the roll-out process is carried out in phases, so it will take some time to reach all corners of the country.

Until then, users can also check manually on the smartphone by going to – 'Settings' >> 'About phone' >> 'System update' >> 'Check Now';

For the uninitiated, Google's Android 5.0 Lollipop which was released to Nexus devices in mid-November were riddled with bugs and to fix the issue, the company rolled out two stability updates- 5.0.1 and 5.0.2.

This apparently forced few Tier-1 brands – Samsung, HTC and Motorola to reschedule the software update release program to a month and finally released v5.0.2 update to their respective devices.

Still, there were reports of glitches present in the last (v5.0.2) update; this apparently forced the Google team to re-work on source codes and has already begun deploying new major MR-1 (Maintenance Release) v5.1 Lollipop to Nexus and Android One devices.

This new update is said to fix major bugs such as Wi-Fi tethering issue, Bluetooth connectivity, CPU wake-locks, which result in heavy draining of battery, Chrome crash, deletion of SMSs when SIM memory gets exhausted and many more.

Last month, news broke that Nexus device owners who just got upgraded to the latest Android 5.1 Lollipop have complained that the nagging memory leak bug is still present and is wrecking phone's performance as all the RAM space is being devoured by a handful of apps.
