I just bought a new phone, and had made up my mind which one to buy until I realized it had no headphone jack. I ended up with a slightly different "copy" of the same Xiaomi model (the Chinese mid range phones now include copies of higher end Chinese phones - Google thinks my phone is a Xiaomi Mix 2; the phone I initially planned to get was [something else] Mix 2; I ended up with a Vernee Mix 2 - they all look the same, but have slightly varying specs)

It'll be an expensive lesson in particular for lower end brands that don't have margins like Apples to cushion them.
