So this issue is on the same phone that started out on ICS? If so, my guess is the phone is fairly old, with limited Ram by today's standards. Have you looked into your Ram utilization? While it's generally a good thing for Android to use as much Ram as possible, I had similar problems with my last phone over time. It would get sluggish and non-responsive, and I think the likely culprit is there was more apps requesting Ram in the background than there was memory available. So the OS was constantly busy killing and restarting apps, which bogged down the over all performance of the phone.
