Hey guys! I've got an annoying lag problem on my Nexus 4. At first when I got it (less than a month ago) it was absolutely lag-free and buttery smooth, the way it should be, but lately I started noticing lag here and there - while I scroll my contacts list for example, or when I flick through my home screens. It's driving me crazy! It only uses up to 500-550MB of ram at most and I don't have that many apps installed or running either. No antiviruses or task killers, just Apex launcher. It's a non-rooted stock Android. Is that normal? Should I do a reset?
