I use an iPhone 6 (16-GB) and it's up to date with iOS 12.4.8 (it does not support running iOS 13).
Does the App Store just identify my phone as iPhone 6 via a physical identifier in the phone, and that prevents me from downloading any iOS version beyond 12.4.8? How might I get around this?
Maybe the drivers for the camera and fingerprint reader in the iPhone 6 are not in iOS 13? But, I might be ok without both of those. Losing GPS, Wi-Fi, or Bluetooth would not be ok.
So, I'd like to just give iOS 14 on an iPhone 6 a look and learn something by doing this. But, I'll probably buy a new phone.

I think the main difference between the iPhone 6 and iPhone 6s that stops iOS 14 supporting the iPhone 6 is probably the fact that the iPhone 6 has 1GB of system RAM (not storage), and the iPhone 6s has 2GB of system RAM.
There is not a lot that could be done to make an OS designed to run in at least 2GB of RAM, work on a system with only 1GB of RAM.
Even if you were able to persuade iOS 14 to install on an iPhone 6, it would run like a dog, if it would run at all.
