There was a review stating that this glass protector would not work with Otterbox. I attached a picture showing it works on a Samsung Note20 Ultra with OtterBox Defender Pro case. You have to remove the case to install.
after getting the glass camera protector, I put it to the test. Having my phone in my pocket, purse, lunch bag, skincare product on hands, and cooking. The camera is still clear to take a picture. Need to have this product for ALL PHONES!!!
