Bought a new phone (Walmart), forgot password, bought another. Daughter would like a new phone -- needs to reset Google password on 1st one? It locked up on "knock code". Got it going again but then google wouldn't let me in without password. Salesman set it up -- what I wrote down wouldn't work and we can't remember. "Reset to factory" status doesn't work without password. Tried to talk to someone at google -- no luck.
