A few months ago, the folks at Google begun rolling out the Android 5.1.1 update for Nexus 4, Nexus 5, Nexus 7, and Nexus 10. Of course, the new firmware was also made available for the latest Nexus terminals, the Nexus 6 and Nexus 9. It's even available for Nexus Play which was actually the first device to receive it. Since the ETA varies with device model, region, and carrier, many Nexus owners haven't got the new firmware on their devices yet. For more information regarding Android 5.1.1 Lollipop Update for Nexus 4, Nexus 5, Nexus 7, and Nexus 10 availability, feel free to read on.
The Android 5.1 update was intended as a maintenance release and it first rolled out early March. The update was aimed to improve the overall system stability and to bring bug fixes, but many users have reported camera crashes, memory leak, and other bugs even after updating to 5.1. Moreover, a number of Nexus 7 owners reported that the Android 5.1 has bricked their tablets.
The main goal of the Android 5.1.1 Lollipop update for Nexus 4, Nexus 5, Nexus 7, and Nexus 10 is to fix these annoying bugs. According to a changelog posted by Google, the update arrives with a fix for camera timeout on the Nexus 5 and Nexus 6, fix/improvement for a recent remote passthrough feature on Chromecast, fixes for security issues, and more.
The Android 5.1.1 Lollipop update is now downloadable for all the members of the Nexus family. It's also worth adding that Nexus 9 skipped 5.1 and got updated straight to 5.1.1 and that Nexus 6 was the last device to get updated to 5.1.1. If you happen to own a Nexus 6 from T-Mobile, Sprint, AT&T, or US Cellular, hear that the update is available for you as well. The new firmware is rolling out over-the-air, but you can also grab it as a factory image from Google's developers page here.
As I was mentioning above, the Android 5.1.1 Lollipop update Nexus 4, Nexus 5, Nexus 7, and Nexus 10 is being seeded in batches, so it can take a while until everybody can download it. Normally, when the OTA update is pushed to your device you should be able to see a message in the notifications bar, letting you know that a new system update is ready to download. Just tap on it and follow the prompts on the screen. If the system update notification failed to appear, you should also try checking for the update manually under Settings > About device > System updates > Check for update. Keep in mind that your device must run an official build in order to receive the update over-the-air. It's also recommended to have the battery charged at above 50%, so the device won't turn off during the installation.
Anyway, there are a couple of methods to grab the Android 5.1.1 update even though you have't received the OTA notification or the manual check returned no result: you can either flash a factory image or to manually update using the OTA ZIPs. The factory image method is good for the devices currently running a custom ROMs, but you can use it with an official build, too. You can even avoid getting your data wiped in the process if you remove the '-w' flags from the 'flash-all.bat' script. Anyway, we can't guarantee it works on all devices.
The OTA ZIP method is quite easy to use and it won't wipe your device, but it only works if your phone or tablet is running an official Android firmware. After you grab the OTA ZIP file, all you need to do is boot into fasboot mode, then use the 'adb sideload' command to flash the firmware on your device.

The tutorials for Nexus 4, Nexus 5, and Nexus 6 are here, here, and here (T-Mobile Nexus 6 tutorial here),while the tutorial for Nexus 10 can be found here.

Summing up, the Android 5.1.1 Lollipop for Nexus 4, Nexus 5, Nexus 7, and Nexus 10 is just a minor update. The new firmware doesn't bring any new features, as it only arrives with bug fixes and improved system stability.
Unlike 5.1.1, the Android 5.1 update also arrived with a number of changes and new features aside bug fixes. One of the biggest changes is the new behavior of the 'Wi-Fi' and 'Bluetooth' tiles in Quick Settings. In 5.1, when you press the 'Wi-Fi' or 'Bluetooth' text in Quick Settings, a list of nearby Wi-Fi networks or Bluetooth devices is opened. I remind you that in 5.0, pressing the said labels opened the 'Wi-Fi' or 'Bluetooth' settings menus. The 5.1 update also introduced animated 'Auto-rotate' tile and the ability to remove the 'Hotspot' and 'Color inversion' tiles from Quick Settings. You can do this by long pressing the tiles and selecting 'Hide'.
The Android 5.1 Lollipop software update also improves the heads-up notifications. So far, when a heads-up notification appeared on the screen, you had three options: wait for it to disappear, swipe it away (also dismissed it from the notifications bar), or tap on it and open the app sending the notification. Now you can also swipe up a heads-up notification, action which will remove the notification from the screen but not from the notifications panel. You should also notice the new 'Until next alarm' option that is now available in 'None' and 'Priority' volume modes and the separate volume rockers for media and ringtone.
The 5.1 update came with a tweaked interface for the contacts creating / editing screen, making it more Material. On the other hand, it brought animations for the icons at the top of the Clock app.
As you may already know, Android Lollipop is the biggest update Google's mobile OS received until now. Without a doubt, the biggest new addition is the Material Design interface which is based on more vivid colors, fluid transitions, realistic 3D effects and shadows, and floating elements. The software update arrives with support for 64-bit processors, along with Android Runtime (ART) for in-app performance boosts.
Android 5.0 also brought a revamped notifications panel and a redesigned Quick Settings area. The usual toggles for Brightness, Wi-Fi, Bluetooth, Auto-rotate, Airplane Mode, and Mobile Data are still there, along with new toggles for Flashlight and Cast Screen and dynamic tiles for Hotspot and Color Inversion. The Hotspot and Color Inversion toggles appear in the Quick Settings area only after you access the two options in the Settings menu. Lollipop also debuted heads-up notifications and brought search support in the Settings app.
The Recents section was renamed as Overview in Lollipop and it has a card-based interface. Overview also comes with document-centric multitasking which allows a selection of apps to display more than one card for easier access. For example, Chrome can show one card for each opened tab.
Android 5.0 also came with multi-user support for phones and lock-screen notifications. The latter feature also allows users to choose how much content apps can show and to set priority levels for each app. I also remind you about two new security features: Screen Pinning which allows you to lock your device to a certain app and Smart Lock which allows you to instruct your device to remove lock screen security when you are in a trusted place or connected to a trusted device.
The update also came with better battery statistics and support for Battery Saver Mode. The device is capable of displaying how long it takes until the battery is fully charged or how much time you have left until the battery runs out. On the other hand, Battery Saver Mode aims to conserve energy by shutting down unnecessary processes, limiting data usage and sync, or turning off animations.
