Review on Protector BIGFACE Tempered Friendly Anti Bubble Cell Phones & Accessories by Juan Axum

I have taken every precaution to read the instructions, follow the cleaning procedure and apply the screen protector on my new Samsung A71 phone. The app seemed fine until I went shopping and the phone ended up in my purse in the cold of my car. The peripheral edge has loosened up a bit, but the lower left corner of the tread has now lifted and appears to be deteriorating. I'm afraid that if I drop the phone because that corner won't be securely fastened. , the screen is not really protected. Open to suggestions.
