I'm thinking about buying this off of craigslist pre owned off contract. I'm used to 3.5 inches, And i'm just wondering, is the 4.3 inches really big for small hands? I don't have super tiny tiny hands, but my hands are smaller than average, and i'm just worrying its going to feel big and cumbersome. Would I be better off with going with a 4 inch screen, or do you think I will be fine with this 4.3 inch? Also, does this phone have the tv animation when you lock the screen? And does it have face unlock?
