It won't happen.
Smartphone for bitcoin mining? you are just destroying your phone.
Smartphone as digital wallet, you can simply download an app / wallet and that's how you make it as your wallet.
Yeah smartphones are not capable of mining, mining nowadays is not possible or is useless with the simple CPU, Gpu are used for mining and even the old models of GPU are not efficient for mining. Smartphones are only capable of communication no matter how strong their processor are. You will not be able to fulfil the power need for mining, the batteries of smartphones can not run more than 4 hours of continuous use within a few months.
We're in the bitcoin mining subforum.... You can not make any profit mining with a GPU.
IF you want to mine profitably, you'll need a latest gen ASIC, a very low power price, big starting capital and a (semi)dedicated mining room.
If you got your hands on some of the best GPU's, at current diff and BTC price, you'd make about 14 cents a year mining 24/7... Offcourse, even if you only pay 5 cents/Kwu, the power company would charge you over 65 dollars for the power you've used while mining, making your net profit
minus $65.
