According to a post of a member from Reddit, Android 7.1.1 Nougat is reportedly now available in the Beta channel for the Lenovo Thinkpad 13 Chromebook. The Android version is in the form of the feature-packed 7.1.1 beta, updating the device up from the only basic Android 7.0. Moreover, this update brings for the Thinkpad 13 Chromebook the April security patch level. However, there are not many new features, since Chrome OS is still the main OS and the Android update will only support for running Android apps.
However, you should note that the update is just available if you already registered the Dev Mode, and you are in the Beta channel. Additionally, even you get this update, installing the Play Store and using it also requires some manual tweaking. Once you have the update done, the Play Store will be activated and your device will be listed as compatible with all the same apps based on Android 7.1.1 Nougat OS. You will see that the features are intact, and even in apps that you actually use them. The utility of loading things like Nova Launcher onto a Chromebook is minimal. However, you decide to do, you’ll see that you are able to use app icon shortcuts with a long press, and the new Android 7.1.1 emoji.
This Nougat update comes first in the Canary channel for the Samsung Chromebook Plus and the second-latest version of Android Nougat is rolling out to a large number of Chrome OS devices, which helps Google easier for rolling out the Play Store to these devices. For now, many other Chromebooks are doing the same steps as the Thinkpad 13 Chromebook, as they will enable Dev Mode and use some manual tweaks to bring the Play Store and the latest updates on your devices.
