iPhone XR sound volume very poor. Very hard to hear callers voice in phone call.
I bought iPhone XR on 04.20.21 from apple store. When came out of the store and received a phone call it’s hard to hear the caller voice. I tried to increase sound volume-reset, Face ID and passcode and tried every attempt but nothing happen. I check comments and YouTube to fix it and follow them but I am still unable to hear callers voice clearly. Is iPhone XR totally failed in voice matters? Is there any way out to fix it
