The Bottom Line	Though its design is uninspired, the Samsung SPH-A640 is a functional and well-performing cell phone for midrange users.	If you're looking for a basic and affordable cell phone for just making calls, the Samsung SPH-M300 delivers with style. However, if you want a good camera phone, look elsewhere.	Though the Samsung MM-A900 is unlikely to win over the most hard-core Razr fans, it's still a compelling and promising alternative to the popular Motorola phone.	The Samsung SPH-M320 has a decent camera and nice design, but its call quality could be just a bit better.	The attractive Samsung MM-A920 comes with a great selection of features, but we wish the offerings were more refined.
