I bought and second hand Verizon LG 8.3 a few weeks ago for my wife. She used it trouble free for about 2-3 weeks, but just last week, it has started acting weird. I began with random crashes to desktop during some of the games she plays (Soduku, Wheel of Fortune, etc.) After reset, it wasn't crashing to desktop, but the screen goes blank temporarily then returns to normal. When reading a Nook book, the screen will go blank (not black, just words disappear) and the loading wheel appears. After 1-2 seconds, it returns to the normal page. Additionally, occasionally, the Nook settings bar appears randomly, as well. It has a Otter case, which I removed to test, but the issues persist. I has the stock 4.2.2, and I have not tried rooting or any major changes as of yet. I have tried factory reset 3 times now.
I contacted LG, but they just want it shipped back with receipt (which I don't have), or else they can't do anything. Any ideas here? Can this be hardware related? Should I try rooting first? Wait for the Kitkat update to see if that fixes it, etc?
