There is no way to overlook that the world of Android is an interesting one because the open-source nature gives you the ability to run Android on pretty much every device imaginable with just the right amount of dedication and hard work. The latest gadget that can now run Android 10 happens to be a Nintendo Switch; Android 10 has been ported over to the handheld console thanks to the SwitchRoot team. You can go ahead and install the LineageOS 17.1, which is based on Android 10, on your Nintendo Switch console.

Interestingly, this is not the first time for the Nintendo Switch as it managed to run Android 8.1 Oreo as well, and the same team did the work. This Android 10 is based on LineageOS 17.1 build that is initially for the Nvidia Shield TV, and it brings a lot of improvements over the previous release. You are getting features such as deep sleep mode, which will mean that your console's battery life does not get killed. In addition to that, you are getting a much faster and more responsive experience than the previous release.
