I’m sure I’m doing something to cause this. Just switched from a XR to a 15 pro and about 1/2 the calls I can hear the other person through some static but they can barely hear me, if at all. On the other half of calls they sound crystal clear. Staticky calls are with iPhone users, landlines, and Android users.

I can’t figure it out. The internet isn’t any help.

I have a MOUS case on it, the only thing I can think could cause it but that’s not it.
