Iphone 15 cannot recognize the bluetooth devices

"Iphone 15 cannot recognize the bluetooth devices: I updated the iOS version to 18.3.1; however, after updating the software version, my phone could not recognize my new Bluetooth device (Samsung headphone). It still connects to older Bluetooth devices that were added before. Please help me to solve this problem."
