Technical issue when people ring me

[Cmarie]

For the last week, whenever someone rings me, they get feedback and hear their own voice. When I put my phone on speaker, it's fine. Any ideas on what the issue could be?

Do you have a cover on the phone

Have you tried removing it @Cmarie

Hi! I have tried it without the case and still the same issue unfortunately.
