Its been a while where these mobile phone mining does already exist but most of them are scams and since we are talking for some legit company then i dont see for these things to be feasible.
2 projects that I know that their coins can be earn by mining through the phone.
First Pi Network and another one if I'm not mistaken mangos coin long gone.
But actually these two coins are not really obtained from mining, specifically for the first PI Network because there is no power used from the phone looks good but that's precisely the peculiarity, while the second there must move your cellphone continuously until it reaches a certain amount in a day and can be withdrawn to exchange and convert to btc (I got much profit on this coin).
So to my knowledge so far there hasn't been a project that could actually implement that and I doubt it could be implemented in the future as well.
