Thank you for reaching out. I understand your frustration with your devices not connecting via bluetooth after update. If you cannot connect a Bluetooth accessory to your phone, going through the connection process step-by-step will help. Please see link: https://www.samsung.com/us/support/troubleshooting/TSG01001226/ If this does not help I recommend letting a service technician have a look. As we would like to gather additional information, and look at this from a case by case basis please provide the full model code and IMEI number of the device as well as your best contact phone number, name, and email.
