I just got my 6s a few weeks ago, upgraded from an iPhone 5. I always had a screen protector on the 5 but this time I'm not using any screen protector. Apple did something different because the glass feels smoother and it doesn't leave any fingerprints on the glass. I can use it all day and by the end of the day the glass is still clean. It also feels different to the touch much smoother feel. I'm using the Spigen ultra hybrid air cushion clear back with black color. It goes perfect w my space gray the tpu plastic clear back gives it just the right amount of grip and the black border also gives it grip and it's very thin design. I love it.
