I'm sure you don't want to take a risk using such a expensive phone and regret the screen is scratch resistant. Always having protection is better then regretting later. It's up to you actually. Some people claiming using screen protector makes the stylus not working well but in my situation by using screen protector, it works fine. It's depend on individual actually. I'm going to try  out liquid armor and seen many good review. Waiting for my item to receive. You can use liquid armor too. Basically, having protection is better then regretting later. Good luck.
