Unlike a lot of others, I went straight from a fairly dumbphone... Moto Z6 (did a few 'smart' things, but pretty dumb overall), to this beautiful Samsung Einstein phone that makes me feel like a schmuck. My new phone is definitely smarter than its operator. Anyway, I have a lot of newbie type questions. #1. AT&T didn't put any instruction book or whatever, is there some internet tutorial I can play with for android or samsung? When I google that, I get programming tutorials only. #2. Recommendations on some kinda screen shield or very very thin case... cuz I know I will murder this thing with coins, keys or some other metallic demon. #3. I synchronized Facebook and Google.. now there's a thousand contacts I don't want in my phone. If I hide them, I lose some people I want. Any ideas on how to delete multiple contacts? I can't find it. #4. Please give me your list of must-have applications that everyone loves. #5. I got my phone's "unlock code", put in a foreign sim, and seem to have "unlocked" it, but I think my foreign sim isn't registered anymore "SIM not provisioned MM#2 ". I dont care about the foreign sim, it's long been useless, the carrier definitely de-registered it. I just wanna know if it's unlocked for good now when I travel. #6. One reason I got an android, was because I hated seeing my cousin constantly tied to big fat bloated itunes with his iphone. But it had some advantages that I think he could control some aspects of his phone through itunes such as load apps. Is there an android equivalent to this idea? I like using my computer better to find information on apps.
