I am experiencing a persistent Bluetooth connectivity issue on my Galaxy S22. While my phone detects the Spark 40 amp as “Spark 40 Audio” under Bluetooth settings, the Spark app cannot find or connect to the amp’s Bluetooth Low Energy (BLE) signal, showing “No Devices Found” or “Failed to Connect.”
I have tried standard troubleshooting steps including resetting network settings, clearing app cache, ensuring all permissions are granted, and rebooting the phone. The Spark 40 amp’s BLE signal is confirmed active because it connects properly on another Android device and is visible in BLE scanner apps like nRF Connect.
This issue appears to be a BLE compatibility or software stack problem specific to the Galaxy S22.
