I bought my screen protector from tmobile for my iPhone 11 and they have a deal where if it chips or cracks your can replace it for free. It’s been less than a year and I’ve gone through 10 screen protectors with 2-3 different brands. Before this I had an iPhone plus and another tempered glass screen protector for a year with no issue. Not sure why it keeps breaking because I even use a case that covers the screen .
