As a person who has thrown away a fully functional phone because the camera broke, I now look for the best screen protectors for every new device, and I believe that for the Poco X6, this one is truly THE BEST. It protects the phone's cameras very, very well to the point of making them invulnerable. Personally, I have never applied a screen protector myself because I used to take them to stores to do it. I didn't face any particular difficulty, although there are some small air bubbles left that fortunately do not affect the cameras at all since they are in completely different spots. If you have the option to have a specialist apply it, prefer that solution. As for the distortion of the photo, I have to say that it exists. Compared to photos before and after, I have noticed some distortions that are not too bothersome; they won't affect a user who doesn't take photos often and doesn't seek high quality. In short, personally, in the face of protection, I sacrifice a bit of photo quality, and I recommend it to everyone!!
