Am I misunderstanding this:

"7 of the 18 Android phones never ran a current version of the OS." "12 of 18 only ran a current version of the OS for a matter of weeks or less."

That makes 19 out of 18 phones. That looks like an error. I wonder what other errors there are here?

Yes, it's 7 that were "never" and 5 more that were "weeks", so 12 total that were "weeks or less". I struggled with that phrasing a bit - either way seemed wrong.

[pieter]

"never" is also "a matter of weeks or less"

Depending on what you classify as a "matter of weeks", I count five devices in the latter category.
