Introduction
To protect your eyes from glass shreds and get a better grip to open the phone you might want to apply some tape onto the screen.
You will need replacement adhesive to reattach components when reassembling the device.
What you need
Step 1
Back Cover
- 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.

Step 2
Battery
- Before disassembling your phone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
- 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.

Step 11
Front-Facing Camera
- Use the flat end of a spudger to disconnect the front camera flex cable.
- If you want to go on and remove the motherboard assembly, there is no need to remove the front facing camera after disconnecting it. However if you feel uncertain, carefully remove it with a pair of tweezers.
- 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).

Motherboard Assembly
- 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.

Step 16
- Use an iOpener to loosen the adhesive on all sides of the display.
- If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping over the glass.
- Lay overlapping strips of clear packing tape over the phone’s display until the whole face is covered.
- This will keep glass shards contained and provide structural integrity when prying and lifting the display.
- Wear safety glasses to protect your eyes from any glass shaken free during the repair.

Step 17
- If the broken glass makes it difficult to get a suction cup to stick in the next few steps, try folding a strong piece of tape (such as duct tape) into a handle and lifting the display with that.
- Use a suction cup to lift the upper end of the display until you can insert the tip of an opening pick.
- Only insert the tip of the opening to not damage any components beneath the display.
- Slide the opening pick around all sides of the phone to cut the adhesive.
- Leave an opening pick in each corner of the phone to prevent the adhesive from resealing.
- Don’t lift up the display straight away after you cut the adhesive on all sides. The two display cables are still threaded through the mid frame of the phone.

To reassemble your device, follow these instructions in reverse order.
The best way to secure the new screen is with a sheet of custom-cut double-sided tape. Apply the tape to the back of the screen, then carefully feed the display and touchscreen cable through the frame. Align the screen and press it into place.

Need help: My screen came out so I took the phone apart and re-glued the screen with some 1mm 3M tape. Now I reassembled it and it vibrates on boot and I can see the backlight go on because a corner of the screen is broken off… Also WhatsApp Web works. So the phone is definitely working, but the display isnt showing anything… I re-checked the main screen connector at the bottom and it is properly plugged… what can I do?

Your replacement screen might be bad, or your display cable broke in which case you would need a new motherboard.

Hello,
The secondary screen cable was cut off during the disassembly. Is there any way to fix it or would it be necessary to buy a whole new screen for this purpose?
Thanks.
