Strange you say the Note 3 lags because i haven't encountered any lag yet and I have put it through the paces. I had the G2 for 2 weeks and after having the One as well I would put the LG at the bottom of the list. It lagged so badly for me and not just in games but just scrolling through menus in settings, that is bad. When I wear my polarized sunglasses the G2 screen just becomes invisible, guess it has something to do with their screen technology. Lastly the G2 is would produce this weird effect where I would see a pattern of dots covering every grid on the screen, that and the lag pushed me into the arms of Samsung once again. Other than that i loved the design even tho I routinely hit the power button instead of volume but I so rarely use the buttons that it wasn't an issue, its a beautiful phone and perfect size. Try some polarized glasses on, maybe it was just my device but the lag killed it for me and honestly my Note 3 hasn't so much as hiccuped and I'm on my phone doing whatever non stop every day.
