In error i put the sim card eject tool into the top microphone whole on the Pixel 6 pro. Does this damage the microphone?

Hello Weirdlooking, sorry for the late response, I didn’t see your question earlier. Usually because of the design of smartphones these days, this is nothing to worry about. If I’m correct you mean the microphone opening on the top edge of the phone. Behind this opening sits the earpiece speaker assembly which you can see on the first photo. You insert your SIM opening tool into the round opening with the red rubber gasket around it. However this opening is nothing more than an L-shaped “tunnel” with a second opening at the bottom of the assembly. This is where you can see the white fabric-like material.

The earpiece speaker assembly sits on top of a small part of the motherboard (second photo) with an other opening in it. Underneath this opening sits the actual microphone. I tried to point at it with the bottom arm of my tweezers.

This build protects the microphone with the motherboard, the protective cloth within the earpiece speaker assembly and with that L-shape tunnel. Most likely your SIM tool was blocked by that L-shape and didn’t even touch the protective cloth and you should have nothing to worry about. More or less the same goes for all the other microphones. I hope your phone works fine!

Hi, Try using the phone in loudspeaker mode when on a call and check if you can be heard OK or not or if your voice sounds distorted etc to the other person. Not sure if it is applicable to your phone but with some phones the 2nd mic is also used as a noise cancelling mic in “normal” call mode to minimize any noise picked up by the lower mic. Fancy software algorhythms are used to achieve this
