Accidentally I inserted SIM ejector tool inside the S21 Ultra microphone hole. I also applied some force in an effort to push out the tray. Although, the phone is working OK so far. Did I break something inside? Microphone / Mesh / Water protection. Kindly clear my doubts.
Probably not. You're not the first to do that ;) From reading here the speaker isn't directly under the hole but to the side so it's likely nothing happened.
Fast forward to 1:45 in this video. Remember that you're looking at the back of the camera. The speaker hole is on the top left where the speaker is on the right.
