Good, I've been a couple of weeks now and then, when I have a call, they do not listen to me and I do, I call back and I have no problems.
I did it once last week and again today, although I speak very little over the phone.
What can be? Problems with the network, the sim, or can it also be problems with the iPhone?
I'm worried it's the iphone's microphone.
I have ios 10.3 and tomorrow when I can update to ios 10.3.1 to see if it is solved like that, has anyone else happened to it?
