I have no other conclusion that other than it's now winter, and phone device sees warm/cold temp swing ?
I've never had any other previous phone protectors do this though.

On my IP11Pro with a iCarez glass screen protector, noticed a crack on it last week. Removed/put a new one on Sunday.
4 Days later, same thing. A hairline crack/fracture with 2/3 smaller ones tangeting off the main one. Anyone else have any plausible clues aside from me blaming the ambient temps/temp change

Are you using a case and if so which one? Areas of it could be pressing on the glass causing it to crack.
