Yes! I bought my G4 the first week it came out and it has been fine up until about 10 or so days ago when I discovered it pushed an update to it. Since then, it has become mostly unusable... 50% of my attempts to scroll result in it clicking and following a link, or clicking Like, or whatever happens to be on the screen I'm trying to scroll. Trying to move google maps around is annoying... it thinks I simultaneously press one spot on the screen while swiping, so it suddenly zooms in even though I'm using one finger!
I do not use a screen protector. I've tried hard pressing, soft pressing, swiping slowly, swiping quickly, even cleaning the screen. I've also tried a factory reset -- didn't help in the slightest since it immediately put the latest OS back on it. I've also tried clearing the storage cache, and that was equally useless.
It's also worth noting I've been using various Android phones and tablets since about 2009, and never a problem. So, it is not as if I "don't know how to swipe" or something dumb like that.
I'm quite sure this is a software problem, not a hardware problem since it all started with the update. Sometimes, it'll work properly for a little bit then go back to its bad behavior. I've experimented with it and found that when this happens, the "press" is processed instantaneously upon my finger starting to touch the screen, before it even has a chance to notice if my finger is also moving, or being held there. When it works, my finger can be held there for a moment and it'll give a graphical indication that I'm pressing, but it won't mistake this for a press unless I release my finger.... If I start dragging my finger, it gives up on it being a "press" and proceeds to scroll.
Does anyone have any idea what to do? I paid a lot of money for this phone from Best Buy. But, it is too late to return. It is on AT&T's network. Would I bring to Best Buy, and AT&T store, or LG? Also, does anyone know of any "secret setting" or something that controls how long it might wait for a touch to be a press, etc? Note that I'm not willing to root the phone as that voids the warranty.
