The Unihertz Tank 4 Pro is here, setting new standards for rugged smartphones with its powerful hardware, innovative design, and the world’s first 720P laser autofocus projector integrated into a durable, outdoor-ready frame. After an in-depth review, it’s clear this device is not just a rugged phone—it’s a versatile “internet appliance” designed for professionals, adventurers, and anyone who needs robust connectivity and productivity tools in extreme conditions.
Slimmer, Lighter, and Packing More Tech than Ever
Compared to its predecessor, the Tank 3 Pro, the Tank 4 Pro comes with a slimmer chassis and weighs 530 grams—a significant reduction from 666 grams—making it easier to carry around the field or job site. Despite the smaller battery than the Tank 3 Pro, the device punches well above its weight on performance and features.
Stunning Display Upgrade
The 6.73-inch AMOLED screen boasts a crisp 1440 × 3200 resolution with a smooth 120Hz refresh rate. The upgraded display offers richer colors, better contrast, and a premium viewing experience for media, apps, and outdoor use.
Cutting-Edge Projector Technology
The real standout feature is the new 720p DLP projector with laser autofocus and automatic keystone correction. Unlike the manual focus dial of the previous model, the Tank 4 Pro’s projector adjusts focus automatically, delivering sharp and detailed images at up to 100 lumens brightness. This projector is perfect for impromptu presentations, movie nights, or emergency information sharing even in low-light conditions.
Powerful Performance with Dimensity 8300
Powered by the MediaTek Dimensity 8300 chipset, featuring a CPU clock of up to 3.35 GHz and an adept Mali-G615 MC6 GPU, the Tank 4 Pro offers smooth general performance and can handle demanding apps and some gaming, although it’s not designed as a gaming powerhouse.
