I am using a raspberry pi 2 with raspbian lite, and I wanted to have keyboard control from my phone. So if I hook up my pi to the TV, I can type commands on my phone without needing to connect a keyboard. I found this app called UnifiedRemote that advertises to do just that.
I downloaded and installed the rpi-deb server onto the pi and installed it. I was able to connect to the server via the app, I can browse files, and send the reboot command. However, I don't have keyboard control and I have followed all the tutorials on their website.
How can I get keyboard control for this app? Are there better options for this?
