I've spent some time researching and I cannot find a tough glass screen protector for an iPhone that is also a privacy screen protector. Do they exist? If not, can I just get a Spigen SGP glas.t and put a OtterBox privacy screen on top? I want also either get a Spigen Tough Armor case in gold or an OtterBox Defender case in black and pop the screen out, and use it with the glass.t screen protector + pravacy screen combo. IDK if that is a good plan... (I have the iPhone 5s) Thanks!!!
