Do we have any minning app, that we just install and it gives us bitcoins ?
In the backend it uses oue phone's resources and in return gives us bitcoins ?
You can forget a bitcoin mining phone app because you will break your phone before you would get only one satoshi. Even BCN seems to be difficult to mine on the phone, depending on its processor. But if you want, you could try out the app of minergate https://play.google.com/store/apps/details?id=com.minergate.miner ,just to see, what will happen. I got shares with my old phone (would never us my actual phone), but they got never confirmed. Result: Zero.
There is a newly created mining application mining a token named mibcoin, and the application name is mibcoin miner, this token is not yet listed in any exchanger, but it may be that some exchanger will eventually. If you do not mind shortening the life of your phone, you will not be missing it if it stops working, it's worth the risk. Good profits.
Do you mean this one?
