Too bad I can't attach photos. What I can say in words is a little ... I own Huawei P40 Pro and Huawei P40 pro plus and I ordered front, back and side foil for both, at the moment I put the foil only on the P40 pro to see how it looks I want to mention that I have more I owned Aliensurface foil 6 years ago on an HTC phone that I lost in the Danube RI P and since then I haven't had Aliensurface but I've been thinking about it for a long time: joy :. I am a professional amateur in putting foils or anything like that and I have a few rubbish underneath but the technology it has solves you subtly (the watch tutorial is the coolest seen in all my years of life) returning to the subject with foil, I think it has the best technology a foil can have, absolutely all the air, gel and anything underneath it simply disappears after a few hours any slight scratch disappears after a few hours, it's bestial, it's so thin that it it is noticed on the device, it is invisible, colorless and odorless: joy: :)), without words, the foil comes cut with a mold and the small pieces must be removed from the respective one but I preferred to leave them for protection therefore the one on the sides that opera box and the rest I said to leave it not far away ... What do you think ... The sound does not pass through a 0.10 mm foil if I remember correctly the thickness .... I do not know what has in it probably a meter of wall of concrete so as not to let the sound pass to that nanometer thickness but it's just Wow grade 100 out of 10. Aliensurface for life.
