I have an LG G3, and it has just caused problems. Can't go a single day without wanting to huck it at a wall. It constantly restarts, says that there is an update, and won't update. The messaging app crashes, or never works and freezes. Well, almost all apps crash. I am sick of this phone. I don't know how to go about replacing it. I still have a lot to pay on my tab. Am I stuck with this crap phone till the tab is paid? or can I swap it for something that actually works?
