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.

Hi. I had my screen replaced a few months back. It was repaired by a friend who has been working in the repair industry for most of the past decade. However, the under screen fingerprint scanner no long functions. What is causing this, and how can I fix it? Thanks
