Z fold 3 crazy stuff

I'm posting this to the ZF6 because I think more people can help and read this. So about a year and a half my zf3 inner screen got the circle of death on the crease at the top of the phone not the black streak down the middle phone and then it stopped completely. The other day my dog knocked my phone off the grill trying to snag a hot dog lol. Well my outer screen stopped working it's not cracked just a dent on the hinge and to get even weirder now my inner screen is working again and hasn't since I said a year and a half. Craziest crap I've seen. Anyone in the phone industry or electronics can maybe explain this? Hopefully Samsung reads this and would be curious. Thanks for the help!!
