Factory reset doesn't delete persistent app data enabled by app developer [paraphrased]
What about Erase All Content and Settings? You seriously can't fully erase a second-hand phone you bought?! That's insane

Factory reset doesn't delete persistent app data enabled by app developer [paraphrased]
What about Erase All Content and Settings? You seriously can't fully erase a second-hand phone you bought?! That's insane
What's even worse is that Apple is not fully erasing the phones that they refurbish.
They are fully erasing it. But it's still the same iPhone. With a device ID that is banned.
Apple urges developers to not use DeviceCheck for anything beyond basic device verification, and if you're a developer that's also misusing it, then you should definitely cease that—there are probably more reliable ways to check whether it's the same user trying to access an account from a device or not.
I don’t think I care about not being able to erase the device ID. It seems useful to have this, actually, for back-tracing if need be.
Snapchat probs shouldn’t use the DeviceCheck services improperly. But hey, that’s just like my opinion, man.
More, not very interesting, info on DeviceCheck services here: https://developer.apple.com/documentation/devicecheck
I can’t see what was posted above anymore, but the DeviceCheck API lets app developers store 2 binary digits (that means 4 different states: 00, 01, 10 or 11) per device on Apple’s servers. So, no, these don’t get erased during a Factory Reset as they’re stored on Apple’s servers. But your phone will.
APPLE DOES NOT CARE ABOUT YOU AND DOES NOT CARE ABOUT YOUR PRIVACY
What does AMD has to do with your privacy.

Sounds reasonable…
But then, why would you use it?
For example, you might use this data to identify devices that have already taken advantage of a promotional offer that you provide, or to flag a device that you’ve determined to be fraudulent.
Oh, ok. Wait, what? But…
Luckily Apple strictly controls the App Store and will never allow apps to abuse this, right? Right?
Yeah? That makes perfect sense, don’t use it beyond a basic device verification, for example verifying if the device has already been used in a promo or stolen.
Those are instances where you need to check the device itself not the user.
So getting my iPhone repaired can ban me from a promo that I haven't used yet? How does that make sense.

Good. Snapchat is and always has been such a garbage and useless app.
One more great reason not to use Apple phones.
Maybe a reason not to use Snapchat?
Both is good
Snapchat or iPhones? How about I take none?
Win/Win
Gosh that's sucks people on iPhone using Snapchat.
Says a guy on an android that doesn't even know what Snapchat does.
You're not missing anything.
The equivalent API on Android gets a new id when the phone is resetted.
Weird that Apple doesn't do that on refurbished phones
The hell is Snapchat?
Like social media for even bigger losers
Lol okay
Why would apple not wipe the device completely on repair or when activated?
