The Nexus 5 is yet to get the Android 5.1 update through network carriers, but as of early March, you can upgrade it to Android 5.1 by using factory images from the official Google developers' site. This means that if you're a Nexus 5 owner currently running Android 5.0.1, you don't need to worry about the 5.0.2 update, and can jump straight to 5.1. Head to the update section below to find out the latest Nexus 5 Android update news.
Update: A new build of Android 5.1 for the Nexus 5 has appeared on its official factory image page. The latest build is entitled LMY471, and appears to be a minor update which irons out a few small bugs. If you already have Android 5.1, it's probably not worth installing unless you're experiencing problems with it.
The most prominent features of Android 5.1 are support for multiple SIM cards, HD voice calls on compatible phones, and Device Protection. The latter feature locks your phone until you sign in with your Google account, even if it's reset to factory settings. This could prove a great tool in the fight to discourage phone theft.
