Mouse is implemented with support for the touchscreen as a touchpad or using a real mouse or touchpad. Keyboard support is also implemented. Pressing back/select and start together on your controller will bring up the Steam overlay. Streaming over the Internet is supported.
A root version is provided which has vastly improved support for external mouse input for rooted devices running Android 7.1 or older. Android 8.0 does not require this root workaround, so the normal/non-root APK should be used on those devices.
General requirements for current APK:
Android 4.1 or higher
GeForce Experience 2.2.2+ with a GTX 600/700/900 desktop or mobile GPU (GT-series not supported)
Xbox, PS3 (with SixAxis app), PS4, Moga (HID mode), Shield, or Ouya controller (other controllers may work too in HID mode)
Mid to high-end wireless router (preferably dual-band 802.11n or better)
Good wireless connection to your Android device
Changes in v5.7.7:
- Disabling multi-controller now always reports gamepad 1 being present to fix compatibility with some games that don't handle gamepads reconnecting properly
- Reduced app installation size
