Looking for something to protect my new Samsung S20 FE screen and camera lens and LK came highly rated. Installation of the screen was ok, but found that the cutout of the installation guide frame that snaps onto the phone and the size of the glass seemed too tight. The glass caught on the frame and had to use some effort to push the glass onto the phone. Once the frame was removed, the glass fell into place. No air bubbles or dust caught under the glass, which was great, but the bottom right corner of the screen protector didn't stick to the glass. It seems it may have bent (I know it's glass), may have lost it's stickiness when I had to force the glass down due to the frame or the glass on the phone is not perfectly flat as there's a 2mm x 6mm area that won't stay down. I'm sure this will be a zone for dust collection, so hopefully when I do need to replace the protector, one of the other 2 that came in the pack adheres better. The edges of the protector are rounded, so no "edges" to catch on anything. Cutout for the front camera is more than large enough, but unfortunately, since it is a hole, will be a dust magnet.Now, for the bad part, the rear camera lens protectors. Installation was a bit more difficult as there's no installation guide, and the piece is so small so it's hard to hold and align. After the installation, no air bubbles or dust, so it looked to be a good install. Did some test photos and that's when I started to notice some issues. My 1st test was taking a picture of my lamp, directly at the bulb and did see some flares/ghosting, but it happened without the protector as well, so no big issue. Regular photos in a lit room/area seem fine. The problem wasn't until I took photos using the flash in a dim/dark room. The included pictures show a white cloud throughout the photos when I used the flash, which would destroy a good photo, in my opinion. I'm not sure if it's because the flash transmits light across the glass or if it's the light reflecting back through the glass, but it's definitely not something I want to happen to my photos, so I have decided to take the rear lens protector off and leave it unprotected. Would definitely consider getting the lens protector is LK would cut out the holes for the cameras and just protects the rest of the glass as that may fix the issue bit with slightly less protection.So, my recommendation is to use the screen protector, but be cautious of the guide frame and ensure it fits without any snagging before the installation. In regards to the rear camera lens protector, I would give it a hard no I do not recommend using them. Just to note, this is not against LK or their product, I believe it's just what happens when something goes over the camera lenses that wasn't originally designed to be there. Maybe if the edges of the protector that goes around the flash were blacked out, it may eliminate light transmission across the glass, but who knows.
