- Analysis by KJ David
The 2019 successor to Motorola's Z3, the Moto Z4 is a high-caliber Android phone that's somewhat a heavy-hitter in terms of imaging, although it comes at the expense of its hardware specs.
Starting off with its cons, this Moto Z edition relies on a 2GHz octa-core Snapdragon 675 processor 
that comes off as middling to us, knowing that the best eight-core-powered smartphones around the time of this Phonerated analysis peaked at over 2.6GHz. Its 4GB RAM and 128GB do not sound like big difference-makers as well, although the latter is accompanied by a hearty 512GB memory card slot 
.
Display-wise, the Z4 touts a 6.4-inch OLED screen with an expansive 19.5:9 aspect ratio , although we're not ready to call it a flawless pro just yet, since it settles for a 1080p-only FHD+ definition , instead of shooting for a truly-high-end 2K-1440p sharpness. Having said that, it features an integrated fingerprint scanner and it relies on a respectable 3600mAh battery infused with the brand's signature TurboPower charging technology.
The true highlight of the Motorola Moto Z4's mix of pros and cons, though, comes in the form of a high-resolution 48-megapixel primary camera that challenges those of some leading photography-driven contenders -- it had one of Motorola's largest camera sensors as of this on-paper review. Its key imaging perks include the Quad Pixel technology that combines four regular pixels into a single 1.6-micron unit for sharper-than-usual images, an Ultra HD (3840 x 2160) maximum video-recording resolution, and AI-aided photography.
The Moto Z4 is compatible with Moto Mods , which are various snap-on accessories that accentuate a certain function of the phone -- a few examples include its projector mod, fish-eye camera mod, and a relatively-fresh 5G mod that enables 5G network connectivity .
Also part of its pros and cons is a high-class 25-megapixel selfie camera that, just like its rear cam, comes with the Quad Pixel output (1.8-micron pixels) alongside Cinemagraph and AI Portrait Lighting.
All said, the Moto Z4 caters to mobile photography enthusiasts and multimedia junkies who do not mind dealing with middle-class hardware components.
On-paper Review rating: 
It is nice that the Motorola Moto Z4 can record fancy 3840 x 2160 clips, but we're surprised we didn't find any sign of the Moto Z4 sporting an HDMI port (which comes in handy to watch HD videos on your shiny HDTV without having to move them first to your computer).

The screen is big, making it a phablet: 6.4 inches and a resolution of 2340 x 1080 pixels means about 15.57 square inches and an image sharpness of at least 402.75 dots per inch (DPI)!
The Moto Z4 is not sold with a memory card but it can accept up to 512GB in memory expansion, which is convenient to store pictures and video clips taken with the built-in 48-megapixel camera.
A 48-megapixel camera offers a lot more pixels than most other phones. It also sports these features: AR stickers, Cinemagraph, Google Lens, Live Filter, Night Vision, Panorama, Portrait/AI Portrait Lighting, Spot Color.
The 25-megapixel selfie cam offers an above-average resolution.
