Since a couple of months the iPhone had an issue, the earpiece speaker was too low, no matter that I had all the volume up it was pretty hard to listen to the one talking on the other side. I started to use the phone with the speaker in order to have conversations but I don’t like that way, mostly because sometimes I can’t properly listen and there is no noise cancelation meaning that if there is plenty of noise is quite probably the other person won’t listen to me right.
