If you use your LG OLED as a grading monitor, few things are as infuriating as having the apps launcher pop up every time you get ready to work on a project. I believe my television started behaving like that with the latest firmware update, not sure. Anyhow, here’s how to immobilize the dreaded apps launcher: Settings > General > Home Settings > Home Auto Launch = Off.
I can confirm it’s due to the latest firmware update.
My gf had the same on its B8.
Will follow this, Thanks.
Glad I could help!
