No bubbles, case friendly, and good quality. These two are the only ones I know that work if you are looking for a tempered glass screen protector. I believe they have lifetime warranties so if something goes wrong, just contact the seller. Will report back updates with them.

Thanks. I got these and the work fantastic but they went out of stock right after I bought them.

I had ordered these as backup but I have no idea if they work as the above is working great. There were no reviews when I bought them but it looks like these are crap.

UPDATE:

I installed the GLASS-M screen protector from Amazon and it's holding up very well. It's a full adhesive screen protector and it doesn't just sit on top of the screen. There were bubbles at first but I flattened it out by pushing the bubbles towards the center of the screen. Definitely recommend this one (or the Poetic one).

Very happy LG made the screen flatter so that glass screen protectors can be installed. LG did a great job with the design.. much more ergonomic than Samsung's curved screens and
much more comfortable to use and hold.

So what happened to the other protector that you recommended? Did it only last 6 days?

I didn't try it, but these two are the best recommendation so far. The Poetic brand is not a full adhesive.. it sits on top of the screen.. but the good thing is the black borders help cover the edges of the screen that you can see compared to the Glass M which is shorter as you can see in the photos. I guess it's all preference here.. I prefer a full adhesive so that's why I went with the Glass M. The Poetic brand guarantees no bubbles but you might see a rainbow effect.
