Android 5.1 Lollipop spotted on Android One devices in the Philippines after Indonesia Google

Google has not yet officially announced the Android 5.1 (Lollipop) update for any of its Android devices in its famed Nexus line-up, while the internet is already abuzz with news of Android 5.1 making its second appearance on some Android One devices in the Philippines, following its maiden appearance in Indonesia.

According to Android Police citing Google's official blog, the newest Lollipop build has now been spotted running on two new budget Android One devices, the Cherry Mobile One and the MyPhone Uno, which are expected to go on sale via Cherry Mobile and MyPhone networks respectively, in the coming weeks.

Both the Android One phones feature mid-range specs including 4.5in LCD displays with 854 x 480 pixels resolution, Quad-core Mediatek MT6582 SoCs clocked at 1.3 GHz and 1GB of RAM.

The other common specifications include dual SIM slots, 3G connectivity, 5MP rear camera and 2MP front camera, microSD card, and 1700mAh battery.

The only exception being the internal storage capacity, the MyPhone Uno supports up to 4GB, while the Cherry Mobile One supports up to 8GB.

Though their Indian counterparts are still stuck on Android 4.4.4 KitKat, both Philippines and Indonesia are the first countries to debut Android 5.1 Lollipop on Android One devices, ahead of the update roll out on the Nexus devices.

However, Google has reportedly forced both the Android One smartphone manufacturers to remove the updated OS listing from the specs sheets, until further notice.

In related news, LG Nexus 5 has been spotted running Android 5.1 Lollipop update in recent Geekbench tests conducted by primatelabs.

It is almost certain that Google is currently testing Android 5.1 on a number of devices including Android One and Nexus 5, and hence we could hope that Google releases factory images for the latest Lollipop build very soon.
