S20 FE only uses microphone properly in camera app

Hello,

I recently acquired a S20 which overall works flawlessly, but for whatever reason whatsapp and phone app do not pick up the bottom microphone. its quiet, next to muted; when i raise my voice into the mic it sounds all muffled.

i tested the two mics under the *#0283# and rcv_1stmic didnt react at all to input.

Anyone know a fix? Online I only found to clear cache from the phone app, disable bixby, and readd permissions to the mic; none worked. If anyone can help I'd appreciate it alot, tysm!
