Just a correction for some wrong info I posted earlier re: resolution changing on the G6.
You can do this it is in the performance settings and is reserved for Games to get better performance and save battery.
Much like how Samsung used to reserve it for game centre where the option would have best effect.

Just giving LG's own launcher a try as I pretty much used ASAP since I got the device. It's actually pretty good and very fast once it's cleaned up and apps put in folders or hidden.
Do you utilize LG's Smartworld App Store?
