Design, Features, and Quality Call
There is not much to say about the design of Speed. It is chunky for its size, measuring 5.3 by 2.6 by 0.4 inches (HWD) and 4.8 ounces, and packaged in plastic soft touch. It screams generic, and details such as dated capacitive Android navigation buttons below the display to add to the look chintzy. The micro USB port is also mounted on the left side corner, making it difficult to use the Speed during charging.
Proud of 4.5-inch, 960-by-540 display a respectable pixel density of 245ppi, but it does not look particularly sharp or pleasing to the eye. There is an ever-present, refraction-like grain that robs the display clarity. Colors appear muted and the difference failed to impress; Things get worse as you veer past about 45 degrees off angle. Bezel-free 720p display Sharp Aquos Crystal was better world.
With Boost, Speed ZTE supported Sprint's 3G CDMA (800 / 1900MHz) and 4G LTE (850/1900 / 2500MHz) network. Call quality is about average in my testing. Volume in the earpiece is loud enough for modestly environment, although it has pretty harsh edge that can be triple grid of maximum volume. Shipping via mic is easy to understand, but I have noticed great deal of hisses and pops. Noise cancellation is effective for low, consistent sound, but not quite face the rigors of a strong city streets.
Rounding out the options the 802.11b / g / n Wi-Fi, Bluetooth 4.0, and GPS. Wi-Fi is limited to the 2.4GHz band, which excludes not too tight, faster 5GHz network.
Performance and Android
ZTE Speed is powered by a 1.2GHz quad-core Qualcomm Snapdragon SoC 410, which is more common than the Snapdragon 400 you see in most entry-level and midrange phones these days. It is technically among the first 64-bit chip for Android, but do not expect any kind of performance advantage here, it will perform almost identically with the more common 32-bit Snapdragon 400.
