The Nextbit Robin is currently receiving its update to Android 7.1.1 Nougat. This brings the device to the latest available version of Android. The update isn't actually as large as you might have expected. It weighs in at about 560MB, which is about half the size of most updates going from Marshmallow to Nougat - although this was already on Nougat anyways. The update is available for all Robin's right now, and you can head to the settings (then click on About Phone, Check for Updates) and pull down the update.
Nextbit was picked up by Razer not too long ago, and many had expected that updates might suffer a bit with the acquisition. However, Nextbit did say after the acquisition was announced, that the Nextbit Robin would continue to receive updates and security patches through 2018. Which pits it at about 2 years of updates for the device, and that's about the usual time frame these days. This update also brings the Robin to the April 1st, 2017 security patch, for those that might be wondering. The update isn't going to be as big as the update to Android 7.0 Nougat was, but there are some minor fixes incoming for this version of Android, as well as the latest security patches, which are also pretty important, as is always the case here.
If you have gone to the settings looking for the download, but can't find it, well you can also download the full factory image from Razer Insider, who recently published the entire factory image for users to grab. Making it easier for you to download and update your Nextbit Robin. If you have been looking to pick up a Robin - and now with it being one of the very few devices that's not a Pixel to get Android 7.1.1 - now's a great time to grab one. Especially since you can pick one up from eBay for as little as $130 right now. That's not a bad price for a smartphone with pretty high-end specs, and one that is running the latest version of Android (not to mention one that is from Razer now). The update is available for all, and it's definitely a good idea to install it.
