I need to uninstall everything related to U+. I got an LG V30 ThinQ, all of the U+ apps were preinstalled and impossible to remove wirhout risking my phone. For some reason I cant access LG smartworld store from my country and absolutely everything in the app is in Korean, so I cant understand a single word of it. Korea's time is always in my lock screen; with all due respect, I dont care about Korea's current hour.
