Has anyone ever tried making a glare guard to shield your phone from glare while you're flying? I have an IPhone 6S Plus with a Otterbox defender case (encases the screen) and all of the stock glare guards i've been looking for on Amazon don't seem to fit a big phone spec like that. I'm thinking how hard can it be? Just wondering if anyone ever did that. Ever since I got Google Cardboard, I'm thinking anything might be possible.
