When the Android One program first debuted, one of the biggest promises was the timely update to newer versions of Android, something that is lacking in many of the budget handsets found in emerging markets. Despite this promise, Android One users have been stuck with KitKat for months now. As it turns out, Google was waiting for Android 5.1 before updating the current crop of Android One devices to its latest sweet treat.

The 5.1 update first arrived out of the box for Android One devices shipping in Indonesia, and now the OTA is starting to hit existing Kitkat-based Android One devices as well. Thanks to a new tip, we now have gathered up the OTA Build LMY470 links for the following Android One handsets:

While installing these updates is something you should do at your own risk, the process is generally pretty easy. You start by placing the zip on your Android One device, and then boot into recovery (stock or custom), select the zip and flash it. The update will install, the phone will reboot — and that’s about it.

Anyone get the update for your Android One handset yet? If so, what do you think of the changes so far? Noticeably better performance?
