Samsung SCH-u740 help?

I have a Samsung SCH-u740 and it's great, the only thing is I can't figure out how to zoom in when I'm taking pictures. It acts like it could zoom in, and I don't even need it to zoom in a lot but most camera phones can zoom in at least a little even phones that are way less expensive then my phone. I just can't seem to figure it out and have tried eveything I can think of. Please help if you can!
