The smartphone has a 6-inch screen and is available only through MetroPCS in the U.S. It weighs about 175 grams and is 8.9 millimeters thick.
It has some top-line features found in the latest smartphones, like a USB Type-C port. It also runs on the latest Android OS 6.0 code-named Marshmallow.
The Gorilla Glass 3 screen shows images at a full HD resolution. The handset has 32GB of internal storage, and a micro-SD card for expandable storage. That's a lot of storage for a handset under $100.
The handset is comparable to the new fourth-generation Moto G handset, which is now available unlocked on Amazon.com for $199.99 for a 16GB model. The Zmax Pro has a 13-megapixel rear camera and 5-megapixel front camera, along with an eight-core Snapdragon 617 processor, all of which are also packaged in the Moto G.
The ZTE phone also has a 3,400 milli-amp-hour battery, which provides about 25 hours of talk time and 400 hours of standby time. It also features a fingerprint reader, which isn't commonly found in low-cost handsets.
However, the smartphone lacks some other features. It includes 802.11 b/g/n Wi-Fi, not the latest 802.11ac, which offers a wider range and faster speeds.
The smartphone succeeds last year's ZMax 2, which sold for $149. The handset may be available unlocked and through other carriers in the future, but the company wasn't ready to share details.
