It appears that the Nexus 4 will also be receiving the Android 5.1 Lollipop update, which is pretty surprising. As the Nexus 4 was released back in November 2012, it wasn’t supposed to receive any further update as it has passed the 18 months update window set by Google itself.
Nonetheless, it’s a very commendable move by Google to keep supporting the aging smartphone. It will be even more surprising if it gets updated beyond Android 5.1 Lollipop, but that’s something that can only be answered by Google.
In any case, Android 5.1 brings with it several bug fixes and new features, such as Device Protection and HD voice support. HD voice support essentially makes voice calls clearer on both ends, while Device Protection could potentially reduce smartphone theft. Once the feature is activated, the stolen smartphone cannot be unlocked until the rightful owner of the device signs in with their Google account.
The Android 5.1 Lollipop update for the Nexus 4 should be rolling out soon enough via OTA for Malaysian users. The factory image of the Lollipop update is not available from Google yet, but if you’re keen to flash it anyway, you can download it here. Hopefully, the fact that the Android Lollipop update is bricking some Nexus 5 and Nexus 7 devices won’t apply to the Nexus 4 as well.

Nothing to be surprised of actually. Android did mentioned in their blog back in March stating that 5.1 will be available for Nexus phones, Nexus 4 included. Still, a good move by Google
