Oh wow, I see that now. Thanks and sorry.
I'm still unclear on the launcher question, but I will delete the one I downloaded from the main apps page, and download the one linked above. And before I will do that, I will delete every app and start fresh. Hopefully this all works.
Uber still seems like it's non-functional on the LG Classic unfortunately, as Uber doesn't seem to allow you to log in on the app. The mobile website is very janky, but it does work, so at least there's that workaround for now.
