If your LG G8 ThinQ’s screen is experiencing symptoms described in our troubleshooting page such as dead pixels or irregular touch response, this guide will help to replace the screen and access some functions and/or displays that may be obsolete with a damaged screen.

The LG G8 ThinQ requires disassembly of the entire interior of the device to completely replace the screen.

Before disassembling your device, discharge the battery below 25%.

This phone uses a strong adhesive on the battery and back panel; iFixit’s adhesive remover or high concentration (90% or higher) isopropyl alcohol can be used to make the process easier.

Adhesive can be replaced to closer replicate factory fit and finish.

I did not do this myself, but I now see the labor involved, in addition to the rarity of LG phones. Meaning, I understand why it costs what it does for a professional to do this.
