I'd just like to ask a few people here if they are experiencing slight lag while rotating screen, when keyboard is on. Ex. Go into messages app, and start writing a new message (just to put the keyboard on screen). When the keyboard is on, rotate your device to landscape. The rotation animation isn't super smooth on my iPhone 5. (It works for every app that uses keyboard). The important thing to notice is all the translucency must be turned ON, so turn off increase contrast and try it (+ post the device you're using) I just wanna know if it happens on 5s/5c as well.
