Nexus 5 Android M update
The third and final version of the Nexus 5 Android M developer preview (build number MPA44G) is now available as a factory image on Google's Developer site. You can download the factory image from the link above and flash it yourself using our guide on how to install Android M on the Nexus 5. Be warned that process will wipe all of your data, so make sure you have backed up anything essential.
The over-the-air (OTA) update will be arriving anytime now too. If you want to keep all your existing data on your Nexus 5, you might be better off waiting for the OTA.
Android M was announced at Google I/O 2015 in late May and the first version of the preview was released at the event. A second version was released a little behind schedule in mid-July and the third version arrived on August 17.
According to the accompanying blg post, the final preview version is "incremental" with the main additions being fingerprint scanner support and a change of API level to 23. The blog also confirmed that Android M's official name and version number is Android 6.0 Marshmallow, and that it will be coming sometime "later this fall".
Nexus 5 monthly updates and Stagefright fix
Google previously announced regular monthly security patches for seven Nexus devices, including the Nexus 5, on its official blog on August 5. The aim of this schedule is to disentangle security patches from platform releases, meaning that any security patches that can't be handled by the latest Google Play Services update can be issued in one of the monthly Nexus security updates.
The first of these updates has already rolled out, bringing a fix for the Stagefright vulnerability. The Stagefright patch went out as an OTA update, but a factory image that includes the fix (LMY48I) has also appeared on the Nexus factory images page for those who prefer to flash it themselves.
In case you missed it, Stagefright is an MMS vulnerability that allows an Android device to be exploited by text message, as you can see below.
Nexus 5 Android 5.1.1 update
Meanwhile, the Android 5.1.1 Lollipop update, which includes the Stagefright fix mentioned above (LMY48I), is also available now for the Nexus 5. It is available as a factory image on the Google Developers site.
You can follow our guide on how to get Android 5.1.1 on the Nexus 5 if you'd like to do it yourself, or you can sit back and wait for the OTA. To check whether the OTA is already waiting for you, go to Settings > About Phone > System Updates.
Sprint Nexus 5 Android update
Sprint announced a new build of Android 5.1.1 for the Nexus 5 — LMY48I — on its software update page on August 5, detailing the Stagefright patch. The previous update came on May 13 and listed nothing other than an "update to Android 5.1.1" and "security enhancements" as new features.
T-Mobile Nexus 5 Android update
The T-Mobile Nexus 5 update arrived in the form of Android 5.1 in mid-March.
AT&T Nexus 5 Android update
The AT&T Nexus 5 update to Android 5.1 arrived in late March/early April.
Nexus 5 factory images
The LMY48B build of Android 5.1.1 for the Nexus 5 is available on the Nexus factory image page. The update adds some performance and stability fixes and hopefully irons out a few of the Nexus 5 problems on Android Lollipop.
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.
