Hi I hope I’m in the right place I’m new to the forum. Hi I wondered if somebody could help me please or point me in the right direction. My wife’s iPhone 7 started playing up last week. It has the greyed out speaker on it. If I phone her she can’t hear me and I can’t hear her when she speaks into it. If I take out the Sim card it works for a short while and then goes back to how it was. Very frustrating really I’m sure it only happened after update was done. Surely if the speaker was broken it wouldn’t work at all but it does after I take Sim card out and put it back in for a while then goes back to not working . Very very frustrating.
