Yes, it works, however a bit too unstable for me at the moment.
It is a sort of android screen replicator.
You have to download the remote controller app described here:

You start the HibyCast (host, coming with the firmware upgrade) on the R8, it shows a QR code. You start the HibyCast (controller, downloaded as above) on the android device. It starts camera scanning. You scan the QR code on R8, connection establishes. You can see the R8 screen replicated on android device. You can touch the android, it is replicated on R8.
