> Yes, if they wired it. In my experience, actual design with this best practice is frustratingly rare. Keep in mind how precious board space and GPIOs are in a modern phone. The boards are tiny, and even with 8 or 10 layers, they are still packed with traces on each layer. Add to that, that the processor itself doesn't have a lot of GPIOs left over for a design like this. There are soooo many peripherals these days. Sure, you could use a port extender, but that is (a) another chip, (b) extra board space, (c) extra cost. So that's not going to happen unless something really important needs it, like the audio subsystem.
