I have a Nexus Player. NP remote is... okay but I want more from it. I want a remote that has a 3.5mm plug and receives audio, is rechargeable, has a keyboard (a good plus) and can change volume.
Shield TV remote is good; but at 50 bucks and no keyboard, no thanks. I discovered Rii K25A in Amazon; perfect but it's nearly $40.
I have a rooted Nexus S. Everything is still working well. I'm thinking what apps do I need to put in this old phone so it can be a full fledged Android TV remote.
Edit: added the need of volume controls
the remote app from google themselves works well: https://play.google.com/store/apps/details?id=com.google.android.tv.remote&hl=en_GB
Although I think its lacking volume controls, I'm not sure what app supports that I'm afraid.
