The front-facing camera may be causing problems due to either the ribbon cable not being connected properly or because the camera is broken. This guide should help you fix both problems.

  1. Take your phone and place it screen down.
    • Take your phone and place it screen down.

  2. Start by lifting the back panel using the gap located on the bottom-left side of the phone.
    • Start by lifting the back panel using the gap located on the bottom-left side of the phone.

    • Insert the plastic opening tool into the gap and move it along the edge of the phone until the rear case pops off.

    • Remove the battery from the phone.

    • Remove the 13 screws found on the back of the phone.

    • The screw circled in red is shorter than the other 12 screws. For an easier time when reassembling the phone, store it separately from the other screws.

    • Locate the same gap used in the earlier step

    • Remove the bottom panel by gently lifting using your fingers

    • Remove the top panel by gently lifting with your finger

    • Do not pull up too forcefully, as there is a risk of the top panel breaking

    • Check to see that the ribbon cable is connected properly. If it was not, connect it and see if the front-facing camera now functions as intended. Otherwise, proceed

    • Take the plastic opening tool and gently wedge it under where the ribbon cable is connected

    • Gently lift up to disconnect the ribbon cable

    • Repeat the same process for the other 3 ribbon cables connected to the motherboard

    • Remove the motherboard by lifting gently

    • Take care not to damage the ribbon cables if the other components are functional. Damaging them may result in other components not working

    • Take the plastic opening tool and remove the front-facing camera by wedging it into the sides and under the ribbon cable and lifting up

    • The front-facing camera is kept in place with an adhesive, so it may take some time and effort to get it out. Depending on how much force you are using, it may also be launched across the room

    • Remove the old front-facing camera


To reassemble your device, follow these instructions in reverse order.

Thank you for the detailed guide it was very satisfying to repair this on my own.

please note: Image # 10 through me off for a few moments, until I realized it it was posted in mirror image mode.

For any one wanting to try this fix, I say “Go For It”

Also good to note: on my LG G3 . Once the back cover was removed, the inside back plate, comes apart in two sections the bottom 1/3 ( starting at the USB Charging port) is the first section that came apart.

Then the top section (starting beside the mid section of the battery housing) comes off easily.

Once completely removed, it was very easy to spot that the front facing camera ribbon connector just needed to be reset.

My phone feels brand new again :)

Again thank you

Yes since I have had my LG G3 it's been through alot considering it's now 2018 and it still has the performance needed and still more then alot of phones out there while being like 5 years old.

The biggest issue I have noticed and read about was overheating, in my mind caused by placing the CPU & GPU processors back to back. Luckily many people have come up with simple ways to help this. One in which I used was creating a more robust Heatsink, with just the use of alluminum from a tin can. Which worked great for me. Ya amazingly before I had done this I was seeing temps of up to 90°C which is liysuper high. It surprised me with such a great phone that they missed such an easy design flaw or possibly never had the time to figure out a better way before the release date
