A：1. Ensure your phone (tablet) and Bluetooth device are within a 10-meter effective range, and that there are no significant interference factors such as reinforced concrete walls or floors between them.
2. If your phone is in your pocket, squatting or bending over may block the Bluetooth signal, causing intermittent connections.
3. Keep away from environments with strong magnetic fields and electromagnetic interference, such as near operating induction cookers or cell towers.
4. Test the phone (tablet) connection with another known-to-be-functional Bluetooth device to rule out a problem with that specific device.
5. If all the above factors are ruled out, the problem may be with the phone (tablet)'s Bluetooth. Please back up your data and restore factory settings. If the problem persists, you will need to contact an authorized service center for repair.
