Can I wipe my phone and start over like a computer?

Episode 1146 (57:46)

John from Biddeford, ME

John just wiped all his computers and started over. Can he do the same with his cellphones? Leo says that all cellphones have a reset command that will wipe it and bring back the base default configuration. Leo says while he's at it, he could update it to a more recent OS. But Leo also says that a newer phone would probably serve john better since SSDs can get sluggish over time.
