Thanks! Turns out I had to remove all the screws - even some that are hidden under the metallic part that has the camera and headphone drawings. What’s worse - half of these screws needed a Torx T-5 screwdriver and the other half needed a Torx T-6 ?? For instance, the two screws next to each other that you marked with the red circle, right above the microphone module - one of those needed a T-5 and the other needed a T-6. Makes it almost impossible to keep track of which screw goes where, because they might not be interchangeable. (Either that, or I unscrewed too many parts)
I might come up with a more detailed guide when it’s time to tear apart my (still working) phone. Now I experimented on a broken one.
