Guide overview

Before you begin

This guide shows how to remove and replace the bottom microphone in your iPhone 16 Pro Max. If your iPhone has a hard time picking up your voice, or has intermittent issues, the microphone might need to be replaced. You'll need replacement back glass adhesive to complete this repair. You'll also need a replacement microphone adhesive gasket if your new microphone doesn't come with one pre-installed.

  • Continue peeling away the liner from the adhesive, gently pressing the adhesive into place.
  • If you've correctly aligned the adhesive, the edges will fall perfectly into place.
  • If your adhesive is slightly misaligned, gently pull the long edges into alignment with the frame.
  • If the adhesive begins to crease or wrinkle, remove it and start over with fresh adhesive.
  • If you don't have another set of adhesive strips handy, it's okay to temporarily put your iPhone back together and use it normally without any adhesive. Just keep in mind that your iPhone's water resistance will be compromised until you replace the adhesive.
