Doogee S90 is a modular and rugged smartphone with four functional mods — gamepad, night vision camera, powerbank and walkie-talkie. It is highly waterproof, dust-proof and shockproof for extreme conditions, challenging environments and rugged duty. It has been rigorously tested to perform in the harshest conditions imaginable. It is made to survive temperature extremes, drops and shocks, humidity, salt spray, corrosion, prolonged vibration and more. In fact, it can even work underwater up to 5 feet for 2 weeks. In addition to being tough, its incredibly versatile. It is built around a totally new modular design that lets users customize the phone for any application with powerful add-ons that attach to the back of the phone to change its primary function depending on the immediate need. With its modular attachments, the S90 can add a powerful night vision camera or a walkie-talkie module for communications off-grid. For extended use, a 5000mAh power bank can be added to provide a full 26 hours of use time. It can even become a professional gamepad with a high performance, ergonomic controller module. With the S90, that all changes. Built around a Helio P60 Octa-core chipset and Mali-G72 MP3 GPU, the S90 is up to 25% more energy efficient with a 30% CPU operating boost. Powered by multi-core AI Processing Unity and NeuroPilot AI technology, the S90 is able to deep learn user behaviors and perform facial recognition, scene identification and more advanced features.
