Iphone 12 Pro IOS 14.2.1 Bluetooth issue

I just recently bought Iphone 12 Pro and updated to IOS 14.2.1. But it seems it could not detect any bluetooth devices that I'm trying to connect. But my Iphone XR with IOS 14.2 seems not having this issue. I've tried to reset the network setting and event restore the iphone but the issue still persist. May I know if there's any other way to fix this issue?
I have been facing the exact same problem with my iPhone 12 which is on iOS version 14.2.1; I have even restored my phone couple of times without any luck with the issue. Can someone from the developer community confirm if this is a known issue with the iOS 14.2.1 version or does it indicate a hardware issue?
Any response would be much appreciated.
