I have 2 Xiaomi Mi Note 10 Lite phones. In the first one (probably beginner's luck), I applied the screen protector as follows: I poured the liquid exactly in the center of the screen and slightly pulled it downwards, immediately placed the glass protector, waited for 15 minutes, and then passed the lamp over it for about 2-3 minutes from top to bottom. I saw this in a video on YouTube, I did the same exact steps, and the result was perfect. I tried to do the same exact thing on my second phone and it took me 3 packages to achieve it!!! Conclusion: Applying the glass protector is difficult due to the bubbles created by the liquid (they don't go away as easily as some describe because the liquid also comes off, causing the glass to move and the bubbles to multiply). However, when you manage to do it without bubbles (in my case, I specifically left the additional plastic protector that came with the glass, meaning I only removed the label and wiped the plastic protector of the glass with the wet wipe), the result is fantastic: super smooth, no fingerprints, and double protection due to the plastic protector of the glass that I left on. I hope I helped you with my description and don't get discouraged like I did. If the installation is successful, the appearance and feel are fantastic. Good luck...

3 weeks installed on the screen and successfully passed the first crash test. It landed with force a heavy toy of the little one on the screen and the protection worked perfectly. A small mark on the interior from the "glue" that does not distort or draw attention even with the screen off. I don't want to imagine what would have happened without the protection.

The application requires some attention, enough liquid, and a little playing with the 1-2 bubbles if they are created as mentioned in another comment.

The application is flawless and although I couldn't stick it 100% where it should be and it has a gap on the bottom side, the fears of it coming off disappeared from the beginning. Permanently in the back pocket, in a waist bag, and with rough handling due to work, and it hasn't noticed anything.

In conclusion, it is expensive but very good. Application, responsiveness, leaves no fingerprints, does what it promises. I will definitely buy a second one to have it on standby in case something happens to the one I have.

Update: Yesterday, the first protection was replaced and the second one was installed better and easier than the first. Until the first protection broke, it endured many impacts, accompanied keys and other sharp objects, and did not show any scratches. However, it broke diagonally after several impacts and the replacement was not necessary but fair.

The removal is easy, without residue, and now the new one, properly installed, has greatly improved the left-right movements for window switching. I believe that for the P40 Pro, there is no better screen protection. And with the Puro case with the flip case and the protective cover, it does not create any problems in terms of protection.

I don't know what happened to the other users who gave it a low rating, and it's a shame that those who buy it don't write reviews and comments. I did some research on screen protectors and couldn't find any feedback. You have to empty ALL the liquid onto the screen and let it stick on its own. If there are small bubbles, they will only be around the edges and you can press them lightly until they disappear and the liquid dries (don't touch it, it's probably a bit toxic, wipe it with a cloth...). The liquid moves and you can adjust it exactly where you want it to stay, BUT AS SOON AS YOU PASS LIGHT FROM ABOVE, it hardens IMMEDIATELY. So if there are small bubbles around the edges, press them lightly and pass the light from above WHILE pressing them. If you pour all the liquid, logically there won't be any bubbles anywhere. The fingerprint works about 4/5 times, but it's nothing like a screen protector I got from above that has black on top and bottom. Stay AWAY, it covers a lot of the screen and makes the phone look ugly for no reason. I hope I helped and take 5 minutes of your time to write a review, it helps other people too.
