I have a Gmail account, but don't use it for anything other than hooking it to my Youtube account and my Android Moto G phone with Google Calendar & Contacts. All my e-mailing I do with my Yahoo account that I want separate from Gmail. I installed the Yahoo email app on my phone just to be able to check emails with my phone, since I'm not using Gmail. This Yahoo account, which I got back in 1996, automatically puts people I email into a contact list. Whatever. I don't pay much attention to that. The important people I put into Google Contacts, which I wanted to remain separate from Yahoo. So now all of a sudden I tap on Contacts in my phone and all those zillions of Yahoo contacts are there mixed in with the Goolge ones. Uhg! I pulled up Google Contacts on my computer to see if GC had pulled in all my Yahoo contacts. It hasn't. So this is going on just on my phone. Help! This isn't what I wanted. There are now people I haven't been in touch with for over 15 years in my phone contacts. There are dead people in there. I guess I could go in the phone and painstakingly delete every contact I don't want, but will they just get pulled back in from Yahoo? Which software developer decided this was a great feature? Arg.
