When it comes to the release of Android 5.0 (also known as Android L or Lollipop), there were a lot of delays with newer and popular Android devices. The most recent Android update, 5.1, has been pushed out to many devices, but now version 5.1.1 is available. As expected, the Nexus series will be getting version 5.1.1 first, but it is only a question of when for the Lollipop Update of the Nexus 4, 5, 6, 7, 9, and 10.
According to the Latin Post, Google released factory Android 5.1.1 Lollipop images for the Nexus 4, Nexus 5, and LTE version of the Nexus 9. There still isn't any word on when these updates will roll out over the air (OTA). It is possible to download the firmware from the developers page, at the user's own risk, of course.
As for the Nexus 7, the second-generation of this device has already received its Android 5.1.1 Lollipop last month, according to Beta news. The Nexus 6 still does not have 5.1.1 but it actually does have Android 5.1. As for the Nexus 9 (Wi-Fi only version), the Nexus 10, and Nexus player set-top box, it looks like it should already have Android 5.1.1, but if you are a user of those devices and still don't have it yet, you can download it via one of the links below.
It would appear that a lot of reports of Android Lollipop 5.1.1 on the Nexus series of devices are differing, because Redmond Pie reports that updates have started rolling out to the Nexus 4, Nexus 5, Nexus 7, Nexus 9, and other Nexus Player devices. However, this might be referring to the OTA downloads that are available thanks to a series of links that they provide as follows:
- Nexus 4
- Nexus 5
- Nexus 7 2012 (WiFi)
- Nexus 7 2013 (WiFi)
- Nexus 9 (WiFi)
- Nexus 9 (LTE)
- Nexus 10
- Nexus Player
As we mentioned before, the user takes their own risk if he or she wants to do a download manually method as opposed to waiting for Google to completely get their act together on the build for the Nexus devices and star offering OTA to their customers.
If you are wanting to clear some space in your memory for the Android 5.1.1 update, it is only 25 MB. That isn't a big upgrade as it mostly contains critical bug fixes as well as stability improvements, much of them have stemmed from problems with the initial Android 5.0 release.
The delays in Android releases are related to their development processes. When Google develops a new version of the operating system that they own, they attempt to push it out first to the Nexus devices, which are a series of devices that they own. The reason why it takes longer for other non-Nexus Android devices to receive their Android update is that they run interface programs that can interfere with Android's functionality.
I'm certain that all devices in the Nexus series from the Nexus 4, 5, 6, 7, 9, and 10 will receive a release date for the Android 5.1.1 update soon. Since Google has their big I/O development conference, I'm sure there will be more news about Android upgrades as well.
