There is no way mining can be done on your phone device and even your PC even a graphic card can't generate more hashing power anymore, a standard software with high GPU is liable to mine any coin at the moment, any platform that tells you to mine their coin in their site is prolly a scam project, what it's been done on pi network site is faucets not mining so be aware of these terms while interacting on the forum.
Pi network main aim is bringing in traffic to their site while decieving their customers with mining technique. Stay away from pi network for God sake.
