The first Android ROM for the Switch is here
If you want more flexibility from your Nintendo Switch, you can now install Android on it - regardless of the existing system. Unfortunately, the ROM does not work with newer Switch versions.
If the selection of games on the Switch isn't enough for you, you'll be pleased to hear that you can now install an Android on it. The development team switchroot has ported LineageOS 15.1, which is based on Android 8.1, to the Switch. The whole thing runs on an SD card and is therefore separate from the actual Switch system. You can easily switch back and forth between the systems.

However, the ROM only works with a chip exploit that has since been closed. All Switch devices after July 2018 are not compatible with it. To be able to boot LineageOS, the Switch must be modified with a bootloader such as Hekate. Apart from that, the installation is relatively simple. You can find the instructions on the XDA website.

Android then runs in full functionality in both handheld and docked mode. For example, you can load an emulator from the Google Play Store and play a few SNES games on your Switch. There is even an optional Shield-ifier mode that turns the Switch into an Nvidia Shield TV, which in turn allows you to stream PC games via Nvidia Gamestream.
The ROM is currently still struggling with a few bugs. For example, certain apps do not recognise the Joy-Cons, the screen does not always rotate automatically and sometimes the touchscreen does not respond correctly. Battery life is also not expected to improve with LineageOS. If none of this puts you off, then have fun trying it out.
Being the game and gadget geek that I am, working at digitec and Galaxus makes me feel like a kid in a candy shop – but it does take its toll on my wallet. I enjoy tinkering with my PC in Tim Taylor fashion and talking about games on my podcast http://www.onemorelevel.ch. To satisfy my need for speed, I get on my full suspension mountain bike and set out to find some nice trails. My thirst for culture is quenched by deep conversations over a couple of cold ones at the mostly frustrating games of FC Winterthur.
