High pitch ringing when calling

Hey there,
I’m wondering if anyone else experiences this issue. I find that taking a call normally (and by that I mean using the phone up against your ear), there’s a distinct high pitch ringing that makes taking the call a bit uncomfortable. Could there be a physical problem with the speaker?

I asked about this earlier and it does seem to be a speaker quality issue. I get a tinny quality to certain tones over the speaker as well.

I take it you got no reply or advice?

Nope. Seems to be hit or miss who it happens to and it’s likely a hardware issue. Aka, cheap part.

If the issue is there in Safe mode and after a factory reset, then we can do a warranty replacement to check if that fixes the issue.
