Now that Android has made it to all "big four" national carriers, it was only a matter of time before it visited some of the smaller wireless operators in the United States. U.S. Cellular got its turn earlier this year with the Samsung Acclaim and HTC Desire, and now Cricket Wireless follows with the Sanyo Zio M6000.
Originally introduced as the Kyocera Zio (Kyocera bought the Sanyo brand last year), the M6000 offers a minimalist design and a feature set that centers on the basics. We won't knock it for not offering mind-blowing features--not every Android phone needs to go for the gold like Samsung's Galaxy S series--though we're not pleased that it debuts with just Android OS 1.6 (Donut). Fortunately, however, performance was satisfactory on most fronts.
In more ways than one, the Zio is well suited to Cricket's budget-minded lineup. Of course, at $249 ($229 if you buy it online) it doesn't come at a bargain price, but that's the trade-off for not having to sign a contract. Even better, Cricket's data plan for the Zio and future Android devices is just $55 per month for unlimited voice, data, and text.
As Android phones go, the Sanyo Zio doesn't make a statement. It sports a basic candy bar design with a simple black color, clean lines, and rectangular shape. The result is a sharply utilitarian and somewhat boring look, but we think that it works. The front is almost all touch screen with a few physical controls down below. At 4.6 inches long by 2.3 inches wide by 0.48 inches deep, the Zio is relatively compact and lightweight (3.7 ounces), but it has a comfortable, solid feel in the hand.
The display measures 3.5 inches, which is just on the border of what we consider acceptable for a touch screen. We also approve of the resolution (262,000 colors; 400x240 pixels), which is quite decent for a low-end smartphone. Colors and graphics were vibrant, though we noticed that the auto-brightness feature made the screen a little too dark. Fortunately, you can turn the feature off and adjust it to your liking. The display also features an accelerometer with an adjustable backlighting time.
As with other Android phones, you can populate the display with widgets, wallpaper, and custom folders. Sanyo and Cricket didn't cram much onto the home screen beyond the standard Google search bar. On the other hand, you're awarded only three home screens for customization needs. The display isn't quite as responsive as we'd like, but changing the sensitivity isn't an option on Android handsets. We supposed you'd get used to it, though. The menu is accessible via the usual pull tab; the menu's design follows the normal grid format.
The Home key, menu shortcut, back button, and search key below the display are touch controls. They need just a light press to register your command. The recessed navigation trackball is a tad small, but it's easy to use and responsive. The Zio's Talk button sits to the left of the trackball, while the End/power key sits to the right; both are physical keys.
The virtual keypad and dialpad are unchanged from other Android phones. Thanks to the accelerometer, the keyboard switches to a horizontal orientation automatically, but only when you rotate the Zio to the left. Other exterior features include a 3.5mm headset jack, the volume rocker and the Micro-USB charger port on the left spine. The microSD card sits conveniently on the right spine next to the camera shutter.
As mentioned, we don't fault the Zio for a feature set that's squarely midrange. Yet it's disappointing that it supports only Android 1.6. Yes, the Zio will get an upgrade eventually, but starting with 1.6 at this point is a bit ridiculous. Remember that it's been a year since the original Motorola Droid first debuted with Android 2.0 onboard. What's more, Froyo (Android 2.2) went out to the HTC Evo weeks before the Zio even went on sale.
The Zio's phone book size is limited by the available memory. As expected, you can save multiple phone numbers per contact and fields like a street address, a company name, and notes. You also can assign callers to groups and pair them with one of 16 polyphonic ringtones. Other essential features include a calculator, an alarm lock, voice commands, and a calendar that can be synced with your Google account. And for connectivity, the Zio has PC syncing, USB mass storage, Wi-Fi, and Bluetooth.
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.
