Introduction

Over time, the speaker on the Motorola Moto G4 can crackle or distort audio. This guide will show you how to replace the speaker.

Insert a fingernail or a spudger into the notch on the bottom edge of the phone, near the charge port.

  • Gently twist or pry to open a small gap between the back cover and the body of the phone.

  • While keeping your tool (or fingernail) inserted into the gap between the back cover and the body of the phone, slide it around the corner to begin loosening the plastic clips holding the cover in place.

  • Insert a thin tool (such as one of your tweezer tips) under the red and black battery wires, and slide it underneath the battery connector.

  • Gently pry straight up to disconnect the battery.

  • Pry only from the side where the wires attach to the connector—if you pry anywhere else, you may break the socket.

  • During reassembly, align the connector in its socket and then press straight down to reconnect it, wiggling slightly as you press to help it seat correctly.

  • Strong adhesive secures the earpiece speaker. If necessary, apply heat or a few drops of isopropyl alcohol to help weaken the adhesive and make it easier to remove.

  • Pry up the speaker with a pry tool or a pair of tweezers. Be careful not to damage any surrounding components.

    • If you plan to re-use the speaker, be careful not to pry at it anywhere other than on its black plastic frame, as the speaker is easily damaged. Check the condition of the adhesive around the bottom of the earpiece speaker when you reinstall it. A little heat from a hair dryer or iOpener can help soften the adhesive and make it sticky again.

  • The back of the speaker is magnetic. Be careful to not touch it to other parts of the motherboard.

You should have clearly told us not to use the tweezers in such a way as to touch the bottom side of that speaker box. I accidentally touched the other side with my tweezer while removing which caused a hole in the thin metal membrane. Now my speaker works but has an incredible amount of distortion. You MUST put a warning for these things. Now I have to buy a new speaker module.

The warning should have told us to touch only the plastic black parts with the pointy end of the tweezers
