Aio's chunky, entry-level ZTE Sonata 4G (Hands-on)
The Sonata 4G is aimed at first timers who don't mind a thicker, smaller HSPA+ device.
LAS VEGAS -- You sure don't see a lot of 4-inch smartphones these days, and you certainly don't see them as thick-waisted as the ZTE Sonata 4G, a forthcoming Android smartphone for Aio Wireless, AT&T's prepaid arm.
Yet here it is: a white HSPA+ 4G device with a silver-colored trim that could never be called anything other than entry-level. It runs Android 4.1, for a start, a version of the operating system that has for the most part been completely abandoned, replaced by newer versions. You'll still be able to access a large amount of Google's OS, but things will run a little slower and you may not have access to all of the tinier, baked-in features.
Because of the 4-inch screen size, you'll get quite a sharp and pixel-rich experience with the 720p HD screen, 367 pixels per inch. There's a 5-megapixel camera onboard that can capture 720p HD video, but no front-facing camera (that's not a knock, just how it is).
Internally, the Sonata runs on a 1.2GHz dual-core Snapdragon 400 chipset, and has a 1,780mAh battery. There are only 4GB of internal storage, but if you can pry off the stiff back cover and dig below the battery, your efforts will be rewarded with a 32GB microSD card slot .
If you spend a lot of time with devices of the higher-end sort, the Sonata 4G won't seem like much, but for the right price (which we don't yet know) and the right person, this could be an option.
