Bluetooth can be a crucial connectivity element in most smartphones, as it helps us to connect with peripherals such as AirPods, headsets, wireless mics, and other accessories. But what if you are particularly facing issues like Bluetooth won’t turn on, or won’t stay on. In some cases, the Bluetooth option itself is greyed out and users are not able to connect any device to it.

The Bluetooth connectivity problem on iPhone 12, 12 Pro, and 12 Pro Max is not common and only affects a small group of users.
