This is the one I used, I have no affiliation with them I was just very impressed.
This is my 2nd G8. I dropped the first one and cracked the screen - bought a replacement and a pack of these. It comes with 3 so I threw one on my old phone for the hell of it. It had a few bubbles but they disappeared by the next day somehow and I was able to continue using it before my new phone arrived. My new phone came and I somehow fucked up the 2nd install. Last one I nailed and I literally cannot even tell it is on my phone - so highly recommended!
bro would that adhesive effect the oleophobic coating that comes on the screen?
Ive tried many different glass ones. All of them are edge only adhesive aka garbage. They always find a way to fall off so I switched to these. It's really good imo and I recommend unless you're still intent on getting a glass protector. This will definitely protect your screen from micro scratches.
Check out the Tech 21 Evo Check. I usually use Spigen Liquid Crystal Cases, but I was getting tired of the yellowing. The Teck 21 is slightly more protective (and thicker) but is really nice and screen protector friendly. Got mine on ebay for dirt cheap ($6).
I also highly recommend this screen protector. Install is easy if you follow the directions perfectly but the result is perfect. No bubbles or dust, perfect alignment, crystal clear, and not grabby when you slide your finger over the screen. Here's a link.

I also gave up on the edge only adhesive glass screen protectors. They truly suck.
I'm using a film adhesive paired with a spigen case and it does what I use it for: protect the screen from micro scratches.
