I yearly upgrade on the iPhone for the better modem support. I always buy Apple leather case, also a yearly upgrade, to protect the phone. A number of years ago I had a screen break and I mentioned at the Genius Bar how I did the best I could using the Apple Cases, and they ended up replacing the screen, a $150 charge, for free. This is Apple. You may have had a firmware incompatibility problem. That is what had happened to me when a few month-old AirPod Pro v2 earbud battery lost charge. I have AppleCare+ (I recommend that for all AirPod purchasers because the batteries wear out after 2 years of use). I used the Apple Support app, selecting my device, and selected for Apple to call, which they immediately did. Apple did the CC hold sending out a replacement. When I received it, it did not work, and the reason was that the firmware on the case and airpod earbuds was recently updated and the earpiece sent to me was not. It is a kind of race condition that occurs whenever Apple updates firmware. In the process of trying to get things to work initially with the replacement earbud, I disconnected my AirPods from the phone, following instructions. When I could not get it to reconnect, I tried to contact AppleCare+ for the AirPod Pro with the Apple support app as I had done 2 days earlier, and this time my device was not showing up in the device list, even though I still owned the device. This is an Apple bug. So, I called 800-APL-CARE, but had to wait on hold to talk with someone a couple of minutes. Then I asked to be escalated to 2nd tier tech support. I explained the firmware incompatibility problem to the advisor. I expressed my annoyance since Apple has known about this problem since shipping Airpods, yet never fixed it. The tech rep had me go through a couple of more steps, including the 30 minute charge of the case with the earbuds (they called me back after 30 minutes). Then they resolved the issue for me. So, Apple had 2 repeatable bugs. 1. Firmware incompatibility with parts replacements. 2. Even though I still owned the AirPods Pro with AppleCare+ support associated with my AppleID, when disconnected the phone, it no longer showed up on my device list. But overall, Apple has been great at support. With AppleCare+, you don't have to go to the store for replacements. They send it to you with a CC hold and then have a prepaid label for Fedex Pickup returns. Call Fedex for the pickup, and that is that.
