Can I use a film screen protector as well as the screen protector that comes with the case?
I've had a film protector put on my phone and I'm just wondering if I can put the case on and it still function 100% with the other film on the screen.
I had the same question as you before I purchased my Defender case for my Galaxy S4 so I called Otterbox and asked. The answer I received from the Customer Service Representative was that there is no need for an additional screen protector as the Defender comes with its own protective screen cover. She also added that adding an additional screen protector may cause the case to not properly fit and also may make the touch screen more difficult to operate. Of course, YMMV.
