It's buggy, and it requires root, and will not work with Android 4.2 (as 4.2 I'm told has a new BT stack from one of chip manufacturers instead of based on bluez). https://play.google.com/store/apps/details?id=berserker.android.apps.blueput... It makes the phone act like a Bluetooth HID. Things I've noticed is that occasionally it'll need you to force quit and flush its preferences, and it will crack the shits if you don't start bluetooth early enough before starting it. Free version gives trackpad functionality along with basic keyboard (but doesn't support some keypresses). Some people have complained about it not just detecting, but actively interfering with ad blocking software. FWIW, I didn't try blocking any ads it ran and still found it unsteady at times. I'm not sure why phone as HID device isn't more common. Besides this, old Sony Ericcsons used to have a bluetooth pointer mode, where they'd act as HIDs. Perhaps there's some patents at play, as it seems like a logical feature to me. The idea I should have to install some software on the receiving workstation (VNC, dedicated client etc.) seems like working around a problem that shouldn't technically be there... Now if this app wasn't so buggy.
