Before I talk about the glass, I want to say that I have changed quite a few screen protectors on phones and this is the first Tempered Glass I have installed on my phone. And since I have tried several protectors that leave smudges and scratches that stay forever, especially with the use of the s-pen... I have one thing to say, I saw the light with the glass! Finally, I enjoy the screen crystal clear, bright and I get the maximum it can offer!!!
***However, I leave something for the end

So, about the glass:

-Installation. Fast, super easy. You follow the instructions, it goes on perfectly the first time and you don't have to wait for bubbles or anything else. A good cleaning with the included tools and it's hard to make a mistake. The package has a QR code that leads you to a step-by-step installation video. The package contains 2 Tempered Glasses.

-Fingerprints. You need to delete the previous ones and re-register all your fingerprints. After doing so, I noticed that if the screen has smudges, marks from daily use, etc., it struggles to unlock. It doesn't work the first time... or the second... It takes... more... Sometimes even more... And this happens with all fingers. I have registered 3 by the way. Fortunately, it works the first time if you fog up the screen a bit (like we do with glasses, blowing a bit of warm air to fog them up) and clean it with your shirt, blouse, sweatshirt... Whatever you're wearing. It needs a little rubbing... and it works immediately. ...in short, the fingerprint almost always needs a completely clean screen to work the first time. Otherwise, it struggles. At least for me.
Still, I can say I like that it doesn't let me keep the screen with marks for quick unlocking. I enjoy the quality of the screen all the time and to the fullest!!!

-Value for money is excellent. High VFM without a second thought

-Also, the feeling of scrolling on glass instead of a protector is night and day. The protectors eventually start to slow down scrolling. The finger sometimes struggles. Probably due to the material or the marks that form.

Overall, I'm satisfied as a first glass!!!
For any updates, of course, I will inform you.

Here, we should say that using a case is a given for the S24 Ultra as much as the air we breathe. I don't think anyone doesn't have their phone in a case. I have 4 branded ones and I switch them. Why do I say this...? Because there is still something basic left... The fall...!!!
We have yet to see what happens if the phone falls. Will the glass break easily or not?

I won't hide from you that the main reason I didn't use glass until now is that I saw screens on friends' phones with glass, but the screen looked shattered like a puzzle from top to bottom or cracked at the corners extending to the middle. And when you ask them, "Oh, did your screen break, man?" they answer, "No, it's fine. It's just the glass." Really now???? And you see someone scratching their finger on a screen with countless tiny pieces and you can't see anything because of the endless cracks!!!!
I always hated that and it was the only reason I didn't put glass on until now.
Now you have an S24 Ultra and the whole screen is shiny and you say, come on, it's just the glass...
Change it, man...

***As I said at the beginning, I leave for the end a possibility and it's the reason I bought glass and I'm trying it!!!

If with the glass the phone takes a hard fall and breaks (the glass), I understand. You change it and move on. .....
But if the glass breaks, cracks easily, with the slightest drop or pressure in the pocket etc. and needs constant replacement... Then... Honestly, people are right. You can't keep changing glass all the time. If this happens, I don't think it's worth having glass.
In contrast to the film, which has only one advantage but a very, very important one: no matter how many times it falls, it doesn't break and the phone will never look like that.

A test will convince us about all this. Congratulations for staying until the end.
I will update you with any news.

Update 18-6-2025
Hello again!
After 6 months of use, today I put on the second glass. The first one did break, but after many drops, guys. Definitely double digits in number. It withstood many drops and finally broke, believe it or not, inside the car. It fell from the seat.
Anyway, I have one negative and one positive to note:
- In the end, fortunately, the glass does NOT break easily as I thought. It withstands one, two, even twelve drops.
Of course, always with the use of a good and branded case.
- Fingerprint... I have the impression that while at first it didn't work with the first one, now gradually the situation seems to be improving.
It's as if the phone is learning the instability of confirmation. Like, "You didn't place your finger well or it's a bit dirty, let me unlock the screen for you so I don't get on your nerves even more."

That's my "few" words. I hope I helped.
In conclusion, the use is definitely recommended. I have already ordered the second glass...
