I’ve considered it. I make most calls using a Bluetooth headset anyway. But it’s a Galaxy S9 and getting it open, while doable, would preclude ever restoring the watertight seal. If I were to do it, I’ve done enough microsoldering that I would just buy the schematics from iFixit and do it myself. But one of my main reasons for using a newer model phone is the IP68 rating.
I do disconnect the mics in my laptops.
