I am really interested in phone mining but I am also skeptical if it can be done. Hopefully, they can create a miner that won't burn our phones.
You can get the Electroneum "mining" app which is also a wallet. It doesn't really mine (it is an airdrop). They call this app a mining simulator. For the moment,
the airdrop depends of the power of your smartphone. The more powerful your smartphone is, the more airdrop you are going to receive.
