If you have an iPhone, and there’s no volume when making calls, but speakers seem to be playing music clearly, you’re not alone. This issue occurs when you plugin earphones that are not made by Apple themselves, and can be resolved by a brute force method that we will detail below.
So, what’s the actual no-call-volume issue? Music on your iPhone plays fine, and the microphone works fine too. But the problem occurs when you pick calls – you’ll be unable to hear the person at the other end completely. Sometimes, you can use a headphone or activate speaker mode to hear the other person talk, but if you hold the phone normally, you really can’t hear the person speak.
