Ever since the 6.1 update on my Z Fold 5, my JBL Tunes 510BT headphones randomly disconnect. This just started happening since 6.1. When they disconnect, and I try to reconnect them, I get an error message saying COULDNT CONNECT. I have to wait a considerable amount of time before I can reconnect. This ONLY happ3ns on my Z Fold 5. On my S22 Ultra, they stay connected no matter what.

Hello, We understand how frustrating it is for the Bluetooth to randomly disconnect and not be able to reconnect. A couple of things we recommend after updating your phone is to clear the cache partition through the recovery menu.

To get to recovery mode: 
- Turn off phone
- Once off, hold down volume up and power buttons simultaneously 
- When Samsung logo appears, release power button BUT KEEP HOLDING VOLUME UP until the recovery menu appears
- Use volume buttons to navigate down to clear cache (NOT CLEAR DATA/ FACTORY RESET) 
- Use power button to select. 
If the Bluetooth continues to connect and disconnect, then try resetting the network settings.
  1. From the home screen, swipe up to open the menu.
  2. Tap Settings.
  3. Tap General management.
  4. Tap Reset.
  5. Tap Reset network settings.
  6. Tap Reset settings.
  7. Tap Reset.. After the network settings on your Samsung phone have been reset, you might have to reconfigure certain settings, such as Wi-Fi.

A third step to try is testing the phone in Safe Mode to see if an app is interfering with the Bluetooth connection. https://www.samsung.com/us/support/answer/ANS00062983/

As a final step, perform a complete backup and factory reset of the phone. https://www.samsung.com/us/support/answer/ANS00062029/

If the phone is unable to maintain a Bluetooth connection after all troubleshooting is complete, service is recommended. You can use the following link to find a list of service centers in the U.S. that can do the repair: http://www.samsung.com/us/support/service/location or contact customer support at 1-800-726-7864.
