Hi All, I posted back on 8/26 about selling my Nexus 6 . Well I did sell it now the new owner can not use it because its asking for my gmail account. Is that something to do with Google security thinking its stolen or what?I factory reset the phone before I sold it but I suppose I should have removed my Google account first? How do you go about doing that and is that remedy for my problem? Any help Please ! Thanks in advance.
