If I'm watching a video and I open up the keyboard the video will glitch for a sec or two, but then it works normally.

As far as your buttons, have you messed with Keyboard Config. at all? If you set any button to, let's say Long Press to an app, it will no longer do it's orginal action when you just click that button. You have to go back in and set that button to do the long press action you want and to the original short press action, if that makes sense...
