Re: why do all my contacts continue to stay in my favorite contacts screen(phone) w marshmallow/6P?
Welcome to Android Central! You're talking about the Favorites/Recent Contacts page of the Dialer app? That page usually has the contacts you've starred (i.e., made favorite), along with recently or frequently called contacts. The latter group should adjust on an ongoing basis, depending on who you call--are you saying the list just keeps getting longer and longer?
