I'd suggest in a friendly manner GTFO or use bitwalking app which is an app that you install and while you're walking you generate bitcoin or their own dedicated token which you'll be able to exchange for bitcoin.
Minergate has similar app which you could mine altcoins and not bitcoin in your cell phone but how powerful do you really think cell phones are with their tiny micro processors?
You need GH-TH for Bitcoin mining and KH-MH rates for altcoins mining.
Do you really think smart phones are comparable to these?
