Use the long-press physical snapshot key to enter camera mode quickly and a short press to capture photos immediately without unlocking the screen. Customize the rear sub-display watch face and use touch controls for notifications, music, and quick selfies. For demanding tasks or gaming, enable high-performance mode; the graphene cooling layer helps maintain lower CPU/GPU temperatures. Charge the phone with the included USB 3.2 Gen 2 cable and 120 W charger for fast refill, or use compatible wireless charging pads. Connect uSmart accessories through the uSmart connector for endoscope or microscope support while preserving Type‑C charging functionality.

Recommendations

For outdoor or professional field use, enable the rugged protection settings and keep software updated via the built-in Service Center app. Use high-quality USB‑C cables and a compatible 120 W PD (PPS) charger for optimal charging performance. When shooting at night or long distances, use the 64 MP night vision camera with NightElf Ultra 3.0 and the additional IR LEDs for better detail.
