Brands like IQ Shield (Opens in a new window) offer TPU at very affordable prices, while Zagg's InvisibleShield film (Opens in a new window) is a bit more expensive. Still, it can go edge-to-edge on any phone, it has better impact protection than PET, and it has limited "self-healing" powers for small scratches. It's a flexible plastic that's a huge hassle to install (it involves using a spray solution and squeegeeing out lots of bubbles), doesn't feel very smooth (thanks to its almost rubbery texture), and adds an "orange peel" type glare to your phone's screen. When you think of the screen protectors of old, you're probably thinking of TPU. Then, if and when the protector gets scratched, you can replace it, keeping the actual screen in pristine condition for a later resale. Screen protectors are not perfect-even the best ones are usually between a 7 and 8 on the Mohs scale, which is slightly better than Gorilla Glass-but they allow you to pop your phone in your pocket without worrying. So yes, your screen can still be scratched, and it's probably the sand in your pocket or bag that's causing it. Any object harder than your screen will scratch it, and while Corning hasn't officially released its glass' Mohs hardness rating (Opens in a new window), most testers have found it to lie between a 6 and 7 (the highest value, 10, is as hard as diamonds). These scratches likely come from sand and other particles with hard minerals in them, like quartz and topaz. The scratches aren't deep, but they're definitely there. Take a look at my Google Pixel 2, for example. It is not, however, unscratchable, as some people believe. The iPhone Ceramic Shield screen, also from Corning, is supposed to be even tougher. Corning's Gorilla Glass will not scratch if you rub it with your keys or loose change, which is a big step forward. The glass on your gadgets has gotten a lot more scratch-resistant since the days of the iPod.
