iPad keyboard time lag
Does anyone know a way to fix a perceivable and frustrating keyboard time lag in iPad model 1416 running IOS 9.2.1? A while ago typing in this iPad used to be very enjoyable as it occurred without any noticeable time lag between the key strokes and the characters appearing on the screen. Now, the typed characters don't show up immediately and sometimes they even buffer for about 1 second (or even more) to eventually appearing on the screen, altogether. I tried all methods I could find in the internet (even doing: General > Reset > Reset All Settings).
Sorry for being suspicious, but is it somehow a way of Apple being gently pushing customers with old iPad models (like this one) to be replaced by new models?
