Switching from android to iPhone to get away from Google. I was looking for a used iPhone 6s but daughter-in-law gave me an iPhone 6 that needed the screen replaced. After having the screen replaced and activating the phone there are two things that bother me, (so far) first the volume is very low when talking on phone but they can hear me fine. (volume control doesn't seem to make a difference) They seem muted, in fact volume is about the same even when mute is on. Second thing is the screen does not go off when I move the phone up to my ear so other options get selected. I guess my question is how much of this was caused by the screen replacement?
