I didn’t realise that it was possible to create a hidden folder until about a week ago and up until this point i had never been bothered to try and figure out how to do it. But today i decided to try figure it out as i’ve seen a lot of people talking about it and got curious. I wish i hadn’t. For some added context, i’m 18(f) and i have an older brother 22(m) who was kind enough to give me his old phone as he decided to get the iphone 14. I now have his old iphone 13 (yes i’m giving him money for it). Anyway, i spent ages trying to figure out how to find the hidden folder and i’m honestly embarrassed at how long it took. I moved a random picture into it as i was unsure if it even existed without pictures in there. So eventually i find this folder and it’s locked so i try using face ID to unlock it, doesn’t work. Instead i have to put in my password which isn’t a big deal and i do so. What i was met with has traumatised me and i’m gonna need therapy or something. I won’t go into detail about what was in there, and honestly i don’t fully know as i’ve never swiped off of something so quickly in my life. My brother did a full reset on the phone before he gave it to me so i don’t understand why the contents of the folder weren’t also wiped along with everything else. I’m disappointed in what is very clearly an oversight on apples part and i hope they realise this is an issue before any other younger siblings are traumatised too. My day is ruined. And so is the relatively pristine impression i once had of my SIL.

TLDR:It doesn’t delete the hidden folder when you reset your phone. Do it manually or risk traumatising your old phones new owner.
