iOS 15 Bluetooth problem

I have successfully installed iOS 15 beta on my iPhone X but there are some issues. Bluetooth would automatically be disconnected when I was listening to music with my Sony headset. I think this could a serious problem for me. Anyone could tell me how to solve the problem?

- Question from Apple Community


Apple’s brand-new iOS 15 beta has been released. When enjoying the fresh features for iOS, you need to suffer the bugs in the iOS 15 beta. It would be common to find that some apps cannot be opened or some settings are not right. After all, the new operating system needs to be improved before it is officially pushed.

iPhone Bluetooth not working is often reported by iOS 15 users. Without Bluetooth, you can’t use wireless headset, Airdrop files to another Apple device, play music in your car, or connect other accessories.

iOS 15 Bluetooth problem can be fixed by yourself or you can choose to roll back the iOS update to say goodbye to Apple Bluetooth issues.

Solution 1. Turn off Bluetooth button and turn it on again

Swipe down the screen from the upper right corner. If the Bluetooth button is touchable, you could turn it off and then turn it on. Try connecting the accessories and see whether it works.

Try pair the accessory with another iPhone via Bluetooth to troubleshoot whether it is the problem of the accessory itself.

If the Bluetooth button is always greyed out, or you are sure it is the problem of your iPhone, you need to do some complicated steps to fix the issue.
