Xiaomi Black Shark GS3 Ultra

The Black Shark GS3 Ultra suits anyone looking for a compact device with an AMOLED display and protection against water and dust. Its 1.43-inch display fits information into a small area, while Gorilla Glass covers the screen.

Its stated protection combines IP68 and IP69K with a waterproof depth of 1.5 m. It also has MIL-STD-810H certification for shocks and drops. Navigation systems include GPS, GLONASS, Galileo, BeiDou, and QZSS. Sensors cover heart rate and SpO2, along with an accelerometer, gyroscope, compass, and barometer. A built-in loudspeaker provides audio, and supported messaging includes SMS, email, and instant messaging.

The clear trade-off is that storage cannot be expanded. This device has no NeoScore, so it cannot be placed among other phones launched around the same time. For someone prioritizing protection, navigation, and health sensors in a compact format, those features are all here; anyone who wants expandable storage will need to account for its absence. The verdict comes down to whether this set of functions fits the intended use.
