It's so fucking stupid how #iPhone/#iOS devices can't be fucking unlocked or backed up or accessed through ANY means the moment ure unable to unlock the phone i.e. through passcode when the screen is (partially) broken.
I've experienced this several times before, last time when my first gen SE had an unresponsive screen, and using Touch ID requires you to unlock the phone through PIN first. Same thing here has happened to my mom's 11 Pro Max, where she couldn't use Face ID to unlock the phone, or connect any USB devices to the phone, without unlocking using her passcode first - 'cept half of her screen's unresponsive to touch, so, not possible.
#Apple devices are so 'secure', with the right combination of things happening to your device.. you could just end up being locked out, forever lol.
