Ringke Easy Flex Screen Protector for Samsung Galaxy S21 Ultra Screen Guard, Antibacterial [Edge-to-Edge Protection][ Bubble-Free Scratch Protection ][Designed for Galaxy S21 Ultra ]

I tried the 2 provided in the pack and I believe that both of them had dust underneath the protective film as even after cleaning them with the wipes and using the stickers to remove the dust there were still dust after it has been applied

Quality is good but its not sticking on edge its opening few minutes after i press it back
