I want to repair my LG G8x thinQ Display

@shahrukhraza we do not know what is available in Saudi Arabia but you can do this repair yourself. Since iFixit does not yet have a guide for this, You can use this video even so it is a slightly different, it will show you how to remove your display as well. You can compare it to the the first 3 min of this video which is identical to your model. That way you can compare screen locations etc.

Most likely you will need some heat from a hair dryer etc to loosen the adhesive, not as easy as it is shown in the video. All you would need is heat and then either a razor blade, exacto knife, or even guitar pics to separate the screen from the frame. Again, not complicated. Then fit a new one in reversed order.

The easiest would be to replace the LCD with the midframe. Something like this (Example only)

The assembly is available at many online sellers. I am not sure about delivery to Saudi Arabia etc. That is something you will have to determine.
