One person found an annoying catch with AppleCare device replacements.

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.
  
  What's worse than that is that Apple isn't even deleting the photos that you delete.
  
  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.
- if ot is tied to your device ID and stored on their servers, then no.
- It's pretty crazy. Apple is allowing developers to write two bits of data to Apple Servers which is tied to individual iphones, without the user's knowledge, consent, or control.
  
  This is not okay.

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?
- What good will they do when all Android manufacturers are trying to copy iPhone? No headphone jack, no expandable memory, no removable battery.
  
  I'd rather buy an iPhone instead of a shitty clone that won't receive updates after 3 years.

  You need to look more carefully and androids because there's plenty that are not clones. Very few all clones so you appear to be selecting for your own bias
  
  It never ceases to amaze me how iPhone users think a bump in a version years down the road, keeps them secure while the browser in iOS needs whole god damn system update to upgrade.
  
  You wait for that patch for a Safari vulnerability for whenever Apple feels like it but Android devs can push patch and deploy within days or hours. And also sideload it, if a really important fix would take a long time through regular channels. And also there's more than 1 browser engine on Android, so all users aren't vulnerable to the same exploit at the same time.
  
  But hey, keep on swallowing that Apple marketing wholesale though.
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?
What
AWhat
I wonder if this is related to the issue with old deleted photo re-appearing.
- Sounds more like Apple makes a MAC like string that identifies an iPhone and Snap is creating a database of IDs against Apples wishes.
  
  sorry i meant to reply to another comment under this.
