Setup, Compatibility & Care
To set up your device, insert a NanoSIM card into the dual-SIM tray and proceed with the standard Android 14 setup wizard. Ensure all rubber port covers are tightly sealed after using the USB Type-C port or 3.5mm headphone jack to maintain the IP68/IP69K water and dust resistance.
For maintenance, use only a soft, slightly damp cloth for screen cleaning; avoid harsh chemicals that could degrade the Corning Gorilla Glass 5 coatings. The device is compatible with 66W fast charging to optimize the massive battery life. Always ensure the device is fully dry before plugging in the charging cable to prevent short circuits. For professional diagnostic expansion, use the proprietary uSmart connector to attach approved tools.
