my passcode changed on its own
Hello,
I set up a 4 digit code on my phone, previous to that I had installed a replacement screen for my XS phone, all of the sudden my 4 digit code does not work! it's a code I've used for many many years! it's a number I can't forget, something weird is happening, could I have been hacked by that replacement screen and could they somehow replace my passcode?
