I can’t use speakerphone during call
I have an iPhone 7 plus, everything is functional until yesterday when this problem appear. Speakers work fine when the phone rings or I play music, but during a call, I can’t hear the voice on the other line same as they can’t hear mine. As you can see on the photo, the speaker option is not functioning! I can’t hear if the phone of the person I’m calling is ringing already.
iPhone 7 Plus, iOS 15
