Recently I have been struggling to hear the other person on call.
My call volumn is turned up to the fullest.
Blow / puff air into the speaker. Then tap phone on other hand. Then use a damp cloth on it - on the phone, not on your hand, lol. Try the call on speaker phone. A little harder tap of the phone against your hand next thing if all that fails. Try Voice Clarity on in Call Settings. All things to try before seeking paid for help.
