My current phone is a Samsung Galaxy A32, the last in the A3x line that has one. It’s really nice to have a headphone jack because… well, you plug your pair in, and it just works. You don’t have to worry about Bluetooth connections, or another battery that will die one day that you constantly have to recharge. Also, you get FM radio functionality on your phone, which isn’t really useful, but it’s pretty fun to mess with. I’m surprised Apple never had it on the iPod Touch despite the Nano and Classic both having it (some with a special accessory that unlocks the feature, some have it built in).
Also, support for my phone ends on Android 13 (One UI 5.1), meaning if I want new features (or even emoji updates), I have to get a newer phone, and that means either getting a lower tier model to keep that headphone jack at the cost of performance, or getting the same tier (or higher) at the cost of the jack. And I was never convinced by other Android phone manufacturers either, especially since companies like OnePlus don’t sell their products in my country, so my options are either Samsung, Google, or a whole bunch of Chinese companies, many have really terrible skins of Android. Either that or I get an iPhone, and none of the ones that are currently supported have the headphone jack. So I guess I’m sticking with my A32 until the day it nukes itself.
Sad.
