A lot of Moto E owners have run into a bug where the sound completely stops coming out of the speaker, or it comes out incorrectly. Audio continues to work correctly through headphones. This was caused by a bad connection between the speaker and the main board. If you smack. tap rap or bend the phone, somtimes the sound will work. Here is the cause and here is how I fixed it….
Step 1) Power down phone.
Step 2) Remove the 14 screws from the back cover. These are “hex or spline” screws, but if you don’t have the correct tool, a fine “straight” screw driver will work.

Step 3) Open the phone and carefully fold the rear cover over. Be careful not to break or stress the battery cable.

Step 4) Locate the speaker pads on the main board and clean them. Alcohol is good. Clean the pads and their respective fingers on the back cover. This is where the fault lies. These pads get dirty from micro dust and fail to make good contact with the fingers. That is why “banging” or “smacking” the phone on the back, at this location, temporarily fixes it.


Step 5) While you are at it, clean the pads and fingers for the headphone jack also.


Step 6) reassemble! You now should hear sound as designed. Yippie!!!!
Hope this help...
