1. Device discovery is an interactive process between the phone and the speaker. Sometimes, the phone may experience a Bluetooth logic issue that prevents it from finding the speaker. This is not a speaker malfunction. You can try turning Bluetooth off and back on, or restart your device and search again.
2. If the issue persists, press and hold the Bluetooth pairing button for more than 10 seconds to perform a factory reset. Alternatively, restart the speaker using the power key, and try a forced reboot by holding the Bluetooth pairing button while plugging and unplugging the USB Type-C cable, then try pairing again.
