- Long Batt enabled: Disable this mode.
- Wi-Fi not 2.4GHz: Set your router to 2.4GHz with channel ≤11. If still undetected, test with laptop hotspot set to 2.4GHz.
- Bluetooth data packet mismatch: If 2.4GHz hotspot is undetected, the phone's Bluetooth version may be incompatible. Submit logs, OnelapFit account, and device SN for troubleshooting.
