So it turns out that it's not that tough after all ! Had my phone in top pocket of overalls , bent over to do something , phone fell about 2 feet onto the ground , scratched the samsung screen protector , thought that's OK will remove that , oh dear, deep scratch about 5mm wide ! Ffs !
I told my partner to get a tempered glass. He dropped his also the other day. Left with a mark like a dent on the pre installed protector. Just wondering now if he peels that off the dent may have gone through to the actual screen.
