Review: Sanyo MM-5600
As with most dual display clamshells, this phone makes an excellent watch. The external display is bright, has high contrast and is easy to read under all light conditions when the backlight is on. When the backlight is off, the display switches to monochrome, becoming a virtual digital watch. The phone does not need to be opened to tell the time. If, however the phone is open there are a number of clocks for the home screen to choose from.
The MM-5600 scored 2271 in JBenchmark's MIDP 1 test. This places the phone well within the top 25% of all phones, an rating generally dominated by smartphones. It scored 110 in the MIDP 2 test. Although this doesn't rank quite as high, it is still respectable and better than many high-end phones.
There is an easy to use calculator, with each function mapped to a direction on the D-Pad. The alarm clock has multiple alarms, each with a variety of repeat preferences. Although there is a stopwatch, there is no countdown timer. Sprint and Sanyo include a USB cable in the box, but when the phone is attached to a PC, it is simply a mass storage device, it does not support syncing of contacts / calendars.
