Mirror your device's display to any other 4.3+ Android device
Mirror one device's display to other client device and control the device back from client side.
The device whose content is to be mirrored requires ROOT access and the app must be installed to /system partition.
Notes :-
1. As of now, it works ONLY on a local network.
2. Start the server first, and then the client.
3. In case if things don't work out, try creating hotspot in one device and connect the other one to this.
