Given that the Switch isn’t intended to run an alternate OS whatsoever, the state of the ROM is impressive. Android works in handheld and docked mode, audio and Joycons work flawlessly, and there’s even an optional ‘Shield-ifier’ mode that turns the Switch into an Nvidia Shield TV (complete with support for Nvidia Gamestream and some Shield-exclusive games). However, there are still plenty of bugs, like spotty Wi-Fi and a lack of rotation support.
This is quite an impressive ROM – there are Android phones with crappier LineageOS support than this.
