I updated to the OTA KitKat update, and now have a rather irritating issue that I did not have before. My phone is not rooted, and I'm not using an s-view flip case. I've tried using different lock screens, but it makes no difference.
Since the update, if I press the power button or home button to wake the screen, it sometimes takes 3 - 5 seconds to actually turn on. The strange thing is that if I turn the screen off, then back on within a minute or two, it's as fast as it should be at turning back on. But if the phone sits, untouched, for ten minutes or longer, it takes forever to turn on.
I tried wiping the cache partition, and disabled S voice wake up commands, and double tap to launch S voice.
