Anybody else notice lag when you open apps on the home screen? There is a hesitation that wasn't there on 7.1.2. Right after you touch an icon there is like almost a half second lag till it shoots the app open. Also after launching the App Store it takes longer to load everything in it. Any body else noticing little hiccups in the animations here and there too? I'm sticking with 7.1.2 on my i5 I think! Is there a way to downgrade my iPad 4 back to 7.1.2?
