I had the Anker tempered glass protector but it chipped in a few spots just from normal use. I replaced it with a Nilkin tempered glass protector and it's been flawless. No chips, no bubbles.

If you can find the Spigen Neo Hybrid somewhere (they don't have it listed on their shop anymore), it's worked well for me. Two tumbles, once onto exposed asphalt (volume rocker side) / once onto smooth concrete (face down), and it's fine. No issues aside from a few tiny indents/chips in the case.

Also have this tempered glass screen protector on it. That's the same link from when I bought it in 2014 (looked back in order history to find the name), so you will have to search around for a more current purchase option... but that's enough info to get you started.

first link when I googled it :)
