A Switch 2 controller's Home, Capture and C reach Android only as gamepad keys that no system action answers to, so going home or back from a game, or taking a screenshot, meant reaching for the device itself. On a Retroid Pocket Nova, C on player 1 even arrived as B. Settings now has an Android buttons section with three rows: Home, Back and Screenshot. Each takes one of Home, Capture, C, GL, GR, − or +, and all start as None. A choice applies to every player while the Virtual Gamepad is on, and the chosen button no longer reaches games. Home and Back travel on the virtual gamepad. It gains a trailing Consumer Control collection, and ReportMapper moves a bound button out of the gamepad bits into AC Home or AC Back, which Android reads as HOME and BACK. Screenshot runs `input keyevent 120` (SYSRQ) through the privileged shell, once per press: a Print Screen usage on the pad took no screenshot on the Nova, while the shell command did. Only buttons SidewaysMapper never moves are offered, so a button's id is the same in the player's input and in the report. Emulator configs keep their bindings to a bound button, so setting it back to None needs no new Set up. Android always handles Home itself, so a bound Home leaves the game. Tested on a Retroid Pocket Nova (Android 13) with NSO GameCube controllers: Home, Back and Screenshot each work, and holding the Screenshot button takes one screenshot.
