Review: Sanyo MM-5600
The browser takes about 3 seconds to connect to Sprint's data service, on average, and then renders pages reasonably quickly. Since the phone is sold directly through Sprint, it comes preconfigured, and Sprint's Vision site is set as the homepage. However the browser is not locked to Sprint's portal, allowing you the freedom to browse the mobile web at will. It loads XHTML (WAP 2.0) sites with a great deal of accuracy, even complex ones. It does not, however seem to deal with simple desktop web pages as well as some other browsers.
The browser can take advantage of the incredibly sharp screen by rendering text on pages in a tiny font. This fits a great deal of text onto a page but may cause excessive squinting. The font size can be adjusted to one of four sizes in the browser's menu, from tiny to positively huge. Most pages will render in the font size you choose, however the browser will allow a page to override your choice.
The MM 5600 plays both midi and mp3 ringtones. In addition to downloading ringers, you can load your own ringtones onto the phone. They can be transferred to the phone's memory by using the included USB cable, or simply stored on the MiniSD card. However mp3s stored in the card's "Media" folder for playback in the phone's audio player cannot be used as ringtones.
The home screen and menus can be highly customized, but the menus to do so are confusingly named. For instance there are 3 menu color schemes (including a high contrast black and white for the visually impaired) which are called "backgrounds" in the menu. The wallpapers, meanwhile, are chosen in a different "standby display" menu as screensavers. There are additional clocks, graphics and even the animated rat that can be added to the home screen, should you manage to correctly identify the menu to activate (or deactivate) them.
The flash is actually a multi colored LED which can be programmed to display different colors or patterns for various alerts and activities. Initially it is set to strobe through a rainbow of colors during a phone call. In dark rooms this could cause the "Pikachu effect" and cause seizures among those prone to them.
There is no centralized file manager. Each type of media (pictures, video, downloads, music) is managed through the application that uses them. There is an application called MiniSD, but it is not a manager, instead it simply provides a way to access all the files stored on the card, or reformat the card completely. It cannot delete or move individual files.
