Bluetooth unavailable on iPhone 15 Pro Max

New iPhone 15 Pro Max (this issue is happening another friend of mine also in a different work location). Bluetooth has been fine for 24 hours, as soon as I got to my office building, bluetooth started to crash, and cycle between "unavailable", "on" and "off". Apple tech support said I need to replace my phone. Highly unlikey, it's 99.99% a software issue, possibly with smart focus modes.


When I leave my building, restart my phone, the issue goes away. When I even enter my building the issue happens again, even with location services off. Another reason could be a flood of Bluetooth devices in an office causing the service to crash

cycling between "unavailable", "on" and "off"


This is the exact problem on my iPhone 15 pro max. At the beginning, it is fine. But after I installed an app called kastlepresence to ustilise Bluetooth to open my office lift and door. It started to have this issue but it would disappear if I close that app. And today, it become persistent and my phone cannot even connect my Bluetooth earbuds. Reboot phone a few times and no luck to fix.

Talked to a staff at Apple Store and they confirmed this issue only happens in Australia. Staff who use iPhone 15 Pro at Chatswood Apple Store have the same issue. The staff told me an engineer has been sent from US headquarter to Australia to investigate this annoying issue. Currently there is no fix until an update is available.
