Curious if the S4 has screen lock? I was reading some of the reviews on the VerizonWireless website and a person on there stated that it did not. He also mentioned that he couldn't put his company email on the phone because of this which is also the case with my company email. Here is his quote: "Samsung S4 does not allow you to lock your screen with a pin/password/pattern Basically this phone for me is not functional with screen locked using security. Which basically means I can't have my work e-mail on this phone" Anyone verify this for me? Thanks.
