Samsung A640

Sprint this week rolled out a quartet of basic new phones for summer. They're not high-end phones with EVDO, but each phone serves a purpose in Sprint's full lineup.The Samsung A640 is a rather sleek clamshell phone with a slick OLED outer display that disappears into the glossy black front when it's not shining. The sleek black front echoes LG's popular Chocolate phones. The Samsung A640 is a rather sleek clamshell phone with a slick OLED outer display that disappears into the glossy black front when it's not shining. The sleek black front echoes LG's popular Chocolate phones.Its features are mostly basic. The OLED outer display is multi-color, not full-color. That means the blue parts will always be blue, the red parts always red, etc. Unfortunately, the outer display seemed rather dim to us. OLED displays are usually very bright, but this one seemed to be the exception.The main display is rather small at 128 x 160 pixels. The camera is only VGA resolution. However, the A640 does have Push-To-Talk and Bluetooth going for it. It's on the small and light side, but not exceptionally so.Both the Samsung A640 and A420 have a new high-contrast main menu option for those with poor vision.While Sprint is marketing this feature as a major innovation, it's really nothing more than a very simple main menu theme. It would have been nice to see larger fonts throughout the menus and phonebook, for example. Unfortunately this doesn't include that.
