I am currently using an iPhone 16 Pro Max. Recently, Apple released iOS 26, and after updating to this version, I noticed a possible issue related to the Bluetooth functionality.
When connecting my iPhone to Bluetooth headphones, the connection frequently disconnects and then reconnects after a short period of time. Unfortunately, this happens repeatedly, which makes the user experience very frustrating and unsatisfactory. At first, I assumed the issue came from my headphones, but it appears that many other users have also experienced the same problem. Therefore, I believe this issue may be related to iOS 26 itself.
