Running Volumio on a ZTE Axon 7

Hello all. Is like to run Volumio on a ZTE Axon7 connected to an amp, via headphone jack. The Axon has a capable DAC. I’m thinking that it is a better option than a Pi. I can’t get it to work, though. When I open the app on the phone, it searches for a server, I guess.

I want to be able to control Volumio, on that phone, from another phone or a web interface. What do I need to do? Thanks.

Anyone?

Volumio can’t be installed on such device… Just check downloadable version.
The application is to remote a working device.
