I do agree with everyone else a good pocket camera takes superior photos vs phone cameras. But, there is a way to come out with best possible quality photos if you go the phone camera route. The Olioclip or magnetic lenses from Photojojo are excellent and give you options like macro, fisheye, wide angle, and/or a small amount of zoom. And they're all tiny and will fit in a purse/backpack/jacket pocket no problem. The second half of great phone pictures is to use a photo editing app like Snapseed.
Have fun with your new phone camera!
