Im having issues with my messaging on my nonrooted S3. My keyboard is unresponsive when I press the "p" "back", and long press the "shift" key, although if I keep pounding it enough, it will eventually work. I have been using Swiftkey for a long time now, but it is not isolated to that keyboard, it does it with the factory Samsung keyboard, Google, and Emoji Keyboards as well. I recently updated to 4.4.2, and did a reset immeidately after, and the problem persisted (it was there before the update as well). Frustrated beyond belief, I backed up and did another reset last night, and that seemed to fix the problem for an evening, because it is back doing the same thing again today. Any ideas please?
