Fix: iPhone 12, 12 Pro, 12 Pro Max Bluetooth Connectivity Problem

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. But once this problem hits, you will notice that Bluetooth does not discover nearby devices, especially if you are trying to connect with devices such as car media players, AirPods, or TV soundbars.

I personally use iPhone 12 Pro for casually air casting to my smart TV, but sometimes the soundbar doesn’t connect. The same Bluetooth issue my friend is facing is where his iPhone 12 Bluetooth is not connecting automatically in his car, even when he uses it daily. If you are also facing such issues with Bluetooth lately, then the below troubleshooting will help you fix the issue.
