I got mine just yesterday from the Microsoft Store, it came with a peel-off "features" label on the screen. No way to use it without removing that. I don't have a screen protector on mine at all (I prefer glass-type instead of plastic film) and I'm having the keyboard responsiveness issues too. I have a Lumia 521 that's slow as hell on all other aspects of Windows Phone, but its keyboard is very responsive, so it's definitely a BLU issue. Hopefully it's something they can address in a firmware update soon, and not a hardware specific thing. One of my favorite things about Windows Phone is the (usually) exceptional keyboard, which makes this issue stand out all the more.
