Since the release of the iPhone 7, more and more smartphone manufacturers are ditching the 3.5 mm headphone jack in favor of wireless audio and using dongles. Which I should state that the headphone jack have been a staple of smartphones for over a decade. So there is no reason to change what isn't broken to begin with. There are smartphones out there that still preserved this feature like the Galaxy S8 (thank God). Let this be known to all smartphone manufacturers that the auxiliary port still has a lot of use as it did over a decade ago, so there is no way it should go the way of the dodo.
