That's not to say the device is an unwieldy size. With a 5.2-inch full HD display, the X4 is manageable. The screen's 424 ppi
pixel density also helped make graphics on the phone's
Android 7.1 Nougat interface look rich and crisp.
A nice display is an important basic to nail, but the X4 also has plenty of bonus features even at this price. The most interesting of these is the new dual cameras setup on the rear. Like most other phones with a pair of lenses, the X4 can create an artificial depth-of-field effect that blurs out the background to highlight your subject.
Moto uses a 12-megapixel f/2.0 sensor in tandem with an 8-megapixel wide-angle version in the X4. However, in my short time testing the new phone, I found this software, which Moto calls "Depth Mode," somewhat odd.
The rest of the phone's specs are reasonable for the price. The X4 runs on a
Snapdragon 630 processor with 3GB or 4GB of RAM (depending on the region), and packs a 3,000mAh battery in its IP68 water-resistant body. It also supports Bluetooth 5.0, and uses technology that Moto says allows the X4 to connect to up to four Bluetooth devices at once. Fans of Moto's Maker customization service will probably be disappointed though — the X4 won't have personalization options.
