There were already Android phones who got rid of the 3.5 mm jack, like the Moto Z.
But from now on if the same companies bring out a new phone without the jack, many people will call them out for copying Apple.
I remember when phones had the smaller version, but it was used primarily for headsets.
A little while later, someone released an adapter, and that lessened the annoyance.
But later phones that had 3.5mm (or 2.5mm) in-built were definitely better.
