SuperShieldz Clear Film 2-pack
Another brand I've used on countless products over the years is a SuperSheildz screen protector. They've always been easy to install, have a perfect fit, and last quite long. When I saw they had an updated and improved design for the Note 7, curved edges to make it case friendly, and it came in a 2-pack for less than $4 I knew it was the perfect solution.
If the first install doesn't go smooth, try again with the second one. It's under $4 and will keep your Note 7 looking new for years to come.
