Everything is obviously proprietary, so it's a trust issue. Early specs are - The phone features a 5.65” display with Corning Gorilla Glass 5, an IP68 rating, fingerprint sensor, and dual-SIM support. It comes with 4GB of RAM and 128GB of storage (expandable via microSD), a 5600 mAh battery, and is powered by a Qualcomm Snapdragon 845 chip. The [we hope] secure Katin OS runs on Android 8.1 (upgradeable to Android 9.x). I tried a quick search but could not find any reviews or prices on the Katim that was released in March last year.
I love it when companies throw in meaningless words like "ultra" to make their product seem better than the competition.
