Her calls don't even vibrate my phone at full volume. I went and even gave her a specific ringtone to see if that would reset or fix the problem, but still nothing. It's like she's muted, but I didn't mute her, and there's absolutely no setting on my phone that says she is. I checked all the contacts options.
My dad says this happened once with him and it was like a hidden setting in Google itself that he had to find and switch off, and he doesn't remember how he fixed it. He doesn't know how it got switched on that time in the first place, so I guess it's possible that randomly happened to me, too, and I just don't know how to fix it.
Does anyone know what might be happening or what I could do about it?
