For people who cannot get enough of Android Lollipop, here is some good news.

Google has reportedly finished its Android 5.1 update and it is beginning to roll out on supported devices. Unfortunately, those supported devices as of now include only the Nexus 6 from Motorola and the Nexus 9 tablet from HTC.

According to the report by GSM Arena, the update will bring a number of fixes and improvements. While there isn't an available changelog just yet, some of the changes include HD voice support, Device Protection, and the ability to run on multiple number of SIM cards.

In the report, the multiple SIM card support is mentioned to be particularly important for Google's Android One lineup. Released for the mass market in selected Asian countries, Android One provides a streamlined user experience even in super affordable local brands. 

In fact, in the report, it was the Android One homepage that first displayed the Android 5.1 Lollipop update. This could mean that Google will be focusing its attention on this affordable lineup of handsets.

In addition to the changes mentioned above, Android 5.1 Lollipop will also provide better management for paired Bluetooth devices via the Quick Settings panel. This means users who are fond of connecting to their other devices, or their peers' phones via Bluetooth can manage their connected devices much easier and more conveniently.

The new update also enables Android users to join Wi-Fi networks easier - through the same Quick Settings tab. They do not need to open the settings tab and go through a couple more steps just to search and connect to a new network.

In the report, the Android 5.1 Lollipop update was supposed to go live last month, but the development was stalled due to unknown reasons. The adoption rate for Android Lollipop is still below 10 percent worldwide, although that is slowly changing as more devices are getting their respective Lollipop updates.
