What exactly does Piwik call a "phablet"

In the user sessions I am seeing lots of phablets and actually they are giving me very poor ad traffic. I would like to stop serving ads to them but I don’t know what kind of device they are.

In the Sessions it looks something like this (though it doesn’t say phablet in the debugger):

Devices & platform

454.0, iOS 17.3, Phablet, 375x812

Hi @Marlzzz,

Phablet is a mobile device combining or straddling the size formats of smartphones and tablets. Phablet - Wikipedia.
