droidVNC-NG is an open-source Android VNC server app that does not require root access. It comes with the following feature set:

- Network export of device frame buffer with optional server-side scaling.
- Forwarding of a VNC client's pointer events. To be able to remotely control the device, the included Accessibility API Service needs to be enabled by the user. This allows droidVNC-NG to post input events to the Android operating system. All entered input is directly posted to Android, no input is logged, saved or shared.
- Handling of client-to-server text copy & paste. Note that server-to-client copy & paste does not work in a generic way due to Android security restrictions.
- Handling of special keys to trigger 'Recent Apps' overview, Home button and Back button.
- Android permission handling.
- Screen rotation handling.
- Password protection for secure-in-terms-of-VNC connection.
- Ability to specify the port used.
- Start of background service on device boot.
- Reverse VNC.
- Ability to connect to a UltraVNC-style Mode-2 repeater.
- Functionality to provide default configuration via a JSON file.
- Zeroconf/Bonjour publishing for VNC server auto-discovery.
- Per-client mouse pointers on the controlled device.


Please note that more features are still being added to droidVNC-NG. In particular, most keyboard strokes as of now can only be input via the Android soft keyboard, there is only limited support for keyboard events from VNC viewers (yet).
