i might've found a fix for touch screen issues possibly ?

I haven't really had keyboard issues, but I use Google keyboard and I swipe, not tap to type. I just miss the occasional tap when browsing, etc.
 
My double tap to wake basically never works since getting the phone back from LG a week ago. Super annoying. Triple or quadruple tapping doesn't do the trick. Where I tap and how hard I tap makes no difference either.
