The most important hardware feature of any phone, after the screen, is probably its cameras.
Apple knows this, which is why it pushes them forward every year.

These cameras were considered some of the highest-end compact cameras around at that time.

Like less reliance on flash, for example.
This is a huge deal and may even be surprising.

The trend seems to be clear.
And that’s fine.
For everyone else, we still get better cameras every year, which is great.
