I just upgraded from a Sony Xperia Play to a Galaxy S4 yesterday, and I must say I love the hell out of this phone! Probably the only thing I don't like about it is it won't give me the security I had on my Xperia Play. On the Xperia Play, you had to swipe from side to side to get to the home screen. I added a PIN number after the swipe for an extra level of security. But I can't figure out a way to do this on my Galaxy S4. I can use the swipe which I like but it won't let me combine that with a PIN number. Is there a way to do this, or am I out of luck with it?
