Review on 6 Pack Webcam Cover Black - NanoTech Reusable Adhesive Protection for Laptops, Smartphones, Tablets, Desktops - Works on Any Electronics Surface - Safeguard Your Privacy by Nick Ross

I used this on my Note 9. I cut a piece in half to cover the front camera. The remaining 2 full pieces were glued to the cameras on the back of the phone. I didn't expect them to stay. After about a week, when I was pulling the phone out a dozen times a minute, they started to loosen up a bit. I was able to pull it out of my pocket even though they didn't come off. When they got less sticky I rinsed them off with water and they worked like new. The only thing I removed was the front camera cover. I'm surprised people say they don't stay on their laptops or their suitcases don't close. They seem to be working perfectly. The price is great and works quite well. I found this in a YouTube review. The best lightweight version I've found.
