Introduction
Use this guide to replace the headphone jack in your LG V20.
What you need
-
-
Press the button on the lower right side of the LG V20 to open the clamp that holds the back cover on the back side of the phone.
-
Remove the back cover.
-
-
-
Insert a spudger or your fingernail under the battery at the small recess on the lower edge.
-
Be careful not to deform or puncture the battery.
-
Pry up and remove the battery.
-
-
-
Remove the sixteen 4mm Phillips #00 screws attaching the back cover to the motherboard.
-
-
-
Flip the phone and insert an opening pick in the gap you created.
-
Slide the opening pick along the gap until the frame section pops out of its plastic clamps.
People on Reddit are reporting that the V20's antennas are contained in this top piece, and removing it too forcefully can damage the 2G antenna's contacts, resulting in a loss of ability to make calls. Details and a suggested fix if this happens to you:
-
-
-
-
The loudspeaker is attached to the cover of the motherboard. Use an opening pick to pry it up.
Be very careful with prying up the speaker or else it will break the connection to the cover.

-
-
Use an opening pick to pry up the motherboard cover at the right corner at the bottom of your phone until it pops out of the plastic clamp.
Bonjour, en placant le médiator à l’intérieur de l’emplacement de la batterie le démontage est plus facile de l’intérieur vers l’extérieur…
Merci pour l’info!
In English: it is easier work your way around the inside of the battery compartment rather than around the outside. Also, the clip below the power button (i.e., top of the battery compartment) will release the whole top edge.

-
Use the flat end of a spudger to disconnect the front camera flex cable.
-
Use a pair of tweezers to carefully remove the front facing camera. Be careful to only grip the body of the camera, as the top is the sensor pcb and is only held on with glue (removal will ruin the sensor).
-
-
-
Use the flat end of a spudger to disconnect the flex cable of the left rear camera.
-
The second rear camera will come out with the motherboard since it is connected on the other side.
-
You can leave the front facing camera in its place as long as you're careful while removing the motherboard assembly. However if you feel uncertain, carefully remove it with a pair of tweezers.
-
-
-
Use the pointed end of a spudger to lift up the motherboard assembly until you can get a good grip.
-
Carefully lift up the motherboard assembly and remove it.
Be very careful handling motherboard. The numerous spring-type contact points can be easily bent.
-
-
-
Use an iOpener to loosen the adhesive beneath the headphone jack and its flex cable.
-
-
-
Use a pair of tweezers and gently remove the headphone jack by slowly pulling it up and out of its recess.
The jack connects to the phone via the contacts you can see on its topside in the picture (to matching contacts on the motherboard). There is nothing delicate or electrical underneath it; the jack assembly is just a separate piece taped with the double-sided phone tape to the frame. So there is no need to be super gentle on this step.

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where it’s necessary.
