I was having a bad day. My beloved Pinephone hit the gravel on a hike and the screen shattered. I got home and carefully pulled off the screen protector. Only a couple cracks made it all the way through, and that's just a minor inconvenience at full brightness rather than a death sentence. I slipped on a new screen protector and I'm back in business. Lesson: never buy a phone without also buying a matching screen protector. Bonus points if you have a backup screen protector just in case.
