Speaking of your Google account, the Zio follows every other Android phone in supporting a dedicated Gmail app. And beyond Gmail you can sync most POP3 and Outlook Exchange accounts and use the Zio's text and multimedia messaging features.
For entertainment, the Zio has the standard Donut music player that supports AAC+, AAC, eAAC+, and MP3 formats. Features include album art, playlists, and shuffle and repeat modes, but not much else. Also, the design is pretty basic. We haven't been fans of the stock Android music player from the start, and now, two years after the G1 made its debut, it looks even more dated. On the upside, it's easy to transfer music onto the phone using a USB cable or the memory card.
The 3.2-megapixel camera takes pictures in four resolutions, from 2,048x1,536 down to 640x480. Other editing options include five image-quality choices, a night mode, four color effects, white balance and lighting, auto-focus, exposure modes, and lens shading. After you're finished shooting, the picture gallery app allows you to manage your work and view a slideshow option. Photo quality was quite good. The edges showed a bit of noise, but colors were natural and images weren't too dark.
The camcorder shoots clips in four resolutions, from 2,048x1,536 down to 640x480. Clips meant for multimedia messages are capped at 1 minute, but you can shoot for longer in standard mode. The Zio has about 512MB of user-accessible memory and a 1GB microSD card comes in the box. If you need more space, the phone can accommodate cards up to 32GB.
Naturally, the Zio offers the usual assortment of Google apps like YouTube, Google Talk, Google Search, and Google Maps Navigation. Cricket also put its own touch on the handset with an app for checking your account balance, a contacts backup service, and two games: Uno and Midnight Bowling 2.
The Android Market is the primary destination for more apps, but Cricket and Sanyo have their own portal for downloads. The carrier's Storefront app has sections for ringtones, ringback tones, graphics, and applications, and Sanyo's Zio Top Apps feature offers instant access to popular titles like Facebook, Shazam, and Pandora. We were very pleased to see that the Zio has an integrated File Browser app that allows you to easily locate files both on the phone and the memory card.
Since the Zio uses OS 1.6, the Web browser is fairly basic. Its features include bookmarks, copy and paste, and multiple windows. You'll have to use the magnifying glass tool to zoom as the Zio doesn't support multitouch.
We tested the dual-band (CDMA 800/1900) Sanyo Zio in San Francisco. As the Bay Area is not in Cricket's home network area, we used the carrier's roaming partners during our test period. Call quality was mostly agreeable. On the upside, voices sounded natural and we had no trouble getting a signal. On the downside, however, the volume could be louder and we encountered some static on a few occasions. The latter wasn't too much of a problem, but we did have some trouble hearing in some situations. But even with those caveats, the Zio was a good performer.
On their end, callers said we sounded good enough. They also reported some static, but they agreed that it wasn't overwhelming. Most could tell that that we were using a cell phone. We had to speak up a bit when talking to voice-response systems. Also, it was best when we were in a quiet place. Speakerphone calls weren't quite as sharp. Though the volume could get quite loud, the audio was fairly shrill on our side.
The Zio supports 3G EV-DO data speeds, both when roaming and using Cricket's home network. Data speeds were a tad slow--it took almost a minute to open busy sites like Giantbomb.com--but sites with fewer graphics will load more quickly. And in any case, the Zio will default to the mobile version of a Web site if one is available. Also, remember that we were using Cricket's roaming partner.
Music quality over the external speaker was about average. Here again, the sole external speaker had decent output, but it was a bit tinny and shrill. Seriously, though, we've never expected much from cell phone speakers, so the Zio isn't unique. A headset, whether Bluetooth or wired, will offer a better experience.
The Zio has a rated battery life of 6.9 hours talk time and 13 days standby time. In our battery drain tests, the Zio M6000 had an average talk time of 4 hours and 58 minutes. According to FCC radiation tests, the Zio has a digital SAR of 1.39 watts per kilogram.
