Review on 📱 [3+3 Bundle] TAURI Tempered Glass Screen Protector + Camera Lens Protector for Samsung Galaxy S21 Plus 5G 6.7-inch - Easy Installation, HD-Clear, Bubble-Free - Pack of 3 by Michael Godo

First read the instructions, watch the recommended video. I also read many reviews on Amazon. I saw a review someone wrote that said use a flashlight when cleaning your phone screen. I did so and when I cleaned as instructed the flashlight allowed me to see the dust as I cleaned the screen. Trapped dust prevents a good seal. I placed the screen on the phone, starting at one end and ending at the other. I had a large bladder so I partially raised and lowered it. Use a squeegee and then press firmly to remove the bubbles around the edges. I have no visible blisters. I personally think using a flashlight to see everything on the screen while cleaning made the install a success. Turn off your phone before installation.
