Yea that's especially true now the headphone jack is becoming a thing for history to enjoy only.
This keeps being repeated, but it's really not true. Most people, realising small incremental improvements aren't worth the money, are holding onto their phones for longer periods these days before upgrading - at least two years, often three (or even more). For example, Amir still has an S8+ that was released back in 2017. And I only had an S7 until recently upgrading, with some people I know still using this model, now nearly four years old. Many also choose to buy last year's or even earlier models due to the ridiculous over-inflated release prices of modern phones as well.
This all means that a huge proportion of people are still currently using phones with headphone jacks, and likely will continue to do so for several years to come. Just take a look at top global phone sales for the last couple of years below - apart from the Apple models, every single one of them has a headphone jack:
And that's not even counting all the users who still have phones from previous years (like Amir, and I did until recently). Then of course there are brands like LG which are thankfully continuing to
equip all their new phones with headphone jacks. Even brands like Sony have
brought audio jacks back with their recently announced phones. Motorola have
brought jacks back to a model for which it was omitted in the previous three generations, and
Nokia's latest flagships have them too. And now Google has brought it back with their Pixel 4A (and 4A 5G). This is all due to the fact that a large majority of consumers actually
highly value headphone jacks in smartphones, as they are much more convenient than having to buy a separate dongle that can easily get lost or damaged, they allow simultaneous charging and headphone listening unlike dongles, do not have the potential compatibility problems some dongles have, and the remaining option for consumers, Bluetooth audio, is inferior in audio quality, connection reliability and latency, and yet another device that needs charging with limited battery life (which will also degrade over time).
I wouldn't be surprised if other brands follow Sony, Motorola, Google etc. in bringing back the headphone jack due to popular demand. Even Samsung has backtracked on design 'streamlining' before with its reintroduction of both water resistance and the microSD card slot due to the backlash it received when it omitted these features on their Galaxy S6 model. There's a similar backlash for their latest Galaxy models due to them only having USB-C audio output. In fact,
recent leaks suggest Samsung may bring back the audio jack in their next flagship, the S21. The headphone jack is by no means dead, in fact it's seeing a resurgence among several big name brands. And even if it does die out, it will still have at least a few more years left out in the wild in many consumers' pockets after that.
