Eufycam plus screeching

My new Cam Plus cameras have a loud screeching sound when playing through my phone, when they aren’t screeching they sound like they are under water. Tried reconnecting, turning audio off, have latest versions, turning phone volume down and moving camera, nothing works.

Is it all your cameras or just one? If just one than sounds like the microphone on that camera is faulty. Since its new, I would return it to get a new one.

No, it’s both cameras

Mine is doing the same thing and can’t do anything to stop it on live recording!
Door bell is great but this one I think will have to go back

Same problem, replaced the cam, still the same problem.
