I don't really understand why people are making Mining software for android, while smart phone functions are only for communicating, though now they can also enjoy high quality games. But still, I think the smartphone is not a land or container for mining crypto currency.with the specifications and the current price of smartphone, I do not think it will be worth the income gained from mining using smartphone.
But you can use the IoT networks connected to you smartphone to mine crypto. I even heard about viruses that utilizes your smart-home system (basically everything almost down to your oven) to mine btc. That's kinda scarry.
You probably will not pay attention to higher electricity bills if you afford smart house, and someone else would benefit from it.
