Headset. All my problems began with the last system update. Sometimes the phone recognizes the headset and other times not.
For example, this morning, I restarted the phone and listened to a podcast. Everything was fine. Then, I stopped the podcast and tried to make a call. The phone did not see the headset and only used the phones speaker. This is an SE with ios17.1.2. All these problems began with the last system update.
iPhone SE, iOS 17
