I just upgraded from the Note II to the 4 and I love the phone, the clean graphics are amazing. However I do notice with certain things, the touch sensitivity is a bit 'numb' and not as snappy. For ex, with Instagram, I have to REALLY touch/tap my screen to like a post. With browsing the internet, touch/scrolling just doesn't seem as snappy as my Note II. I've even enabled the 'glove' setting to see if that increases the sensitivity but it doesn't do much. Anyone else notice this?
