The Sanyo MM-7500's 1.3-megapixel camera has resolutions of 1,280x960, 640x480, and 320x240, with three separate quality selections (Fine, Normal, and Economy). The camera also features a digital zoom; a 5- to 10-second self-timer; four fun frames; a flash; seven color filters; a brightness control; white balance with four settings; and three shutter sounds. The phone's internal 70MB of memory holds up to 145 high-resolution pictures or more than 1,500 at the lowest resolution. Once you take a photo, you can attach a 10-second voice memo to the picture and send it to a phone number, an e-mail address, or the Sprint server, as well as assign a picture as a screensaver or a picture ID. The MM-7500 supports PNG, JPEG, BMP, and WBMP images. Pictures are sharp and clear, with distinct colors.
The Sanyo MM-7500 also has a decent camcorder with a number of options that optimize it for every situation. When using the highest-quality setting (176x1,440), you can take only a 15-second video. The longer 30-second videos at the lower setting (128x96) weren't nearly as nice-looking. The MM-7500 supports MPEG-4, 3GPP2, and 3GPP formats. Features include programmable cue sounds and storage of up to 135 clips; six video modes, including Soft Focus and Night; a digital zoom; and editing options similar to the still camera's.
You can customize the Sanyo MM-7500's external- and internal-display color settings, wallpaper, screensavers, and animations. We were able to set 10 shortcut keys using the Favorites list for easy access to our favorite features. The MM-7500 also has a call-screening option, which allowed us to use a prerecorded message, a custom name, or a custom 12-second announcement. If you want more of these options, you can download them through the WAP 2.0 wireless Web browser. You get six Java (J2ME) games.We tested the dual-band, dual-mode (CDMA 800/900; EV-DO) Sanyo MM-7500 on the Sprint network in San Francisco. Reception was excellent, with no dropped calls, and callers didn't report any problems either. At first, voice quality varied from sounding exceptionally loud and clear to muffled and hollow, depending on how we held the phone, but these concerns eased the more we used it. The external speaker distorts somewhat at the higher volume levels but is impressive for a handset speaker. Even the background noise and the clipping usually associated with the speakerphone remained at a minimum. The MM-7500 also comes with a decent headset.
The Sanyo MM-7500 didn't warm up when using the media services for viewing video, but a 30-minute conversation caused noticeable heat. Sound quality did not decline when we used the phone for extended periods of time, and we didn't get any interference from car or computer speakers.
As a full multimedia solution, the Sanyo MM-7500's performance is certainly in question. While the download and connection speeds are quick, we wish the playback times on the music player were quicker. Also, the songs load so slowly that they require a progress bar, which covers the name of the song. As a result, you can't see the name of the song until it's completely loaded. We are excited at the prospect of an all-in-one phone that incorporates a functional music player, but unfortunately, Sanyo is not quite there yet. We listened to the live radio service, which worked well and came in very clear.
Our other complaint is in regard to the video playback. While we have already cited the lack of a high-quality screen, which obviously affects the video playback, we were also disappointed with the buffering of streaming video when attempting to replay a clip, as well as the mismatched sound and video, which never quite seemed in sync. The browser functioned quickly, but we had repeated connection failures. Downloadable 3D-animation games have excellent-quality gameplay, with quick loading and clear resolution.
Battery life was uneven. The Sanyo MM-7500 has a rated talk time of 3.4 hours and a promised standby time of six days. In our tests, we got 3 hours, 41 minutes of talk time but only four days of standby time. According to FCC radiation tests, the MM-7500 has a digital SAR rating of 0.98 watts per kilogram.
