Its odd. It happens when the phone is on for a few hours. I've booted into safe mode, gone through my apps one by one, and that took no time at all being as I have four apps on my phone that it didn't come pre loaded with, and they're all from the play store/market. Its doesn't appear to be an app issue.
I use the stock manager, no task killers...its strange, when I first turn the phone on, its fast and snappy... or as fast and snappy as its been since the last ota... after a few hours, the phone gets slow and unresponsive to the touch. I literally have to tap home four or five times to get it to respond. Not just home but any of the touch buttons.... however the screen stays somewhat responsive.
The issue cones and goes, like a lag. Oddly I have tons of free memory everywhere on this thing.... starting to ponder the bad egg theory....
