I have already moved on from my iPhone SE. I've got an LG Stylo 3 that works very well... headphone jack, removable battery, micro SD card. The only downside is that it is larger than I prefer. Stylus support makes up for it so, not so bad.Good luck finding any decent mobile phone with a headphone jack in the near future. Apple will never add the headphone jack back to their mobile devices.
But I understand that option is not for everyone. I'm equally comfortable with iPhones and Android phones and so I'm not limited by what Apple chooses to do. I'll switch back to an iPhone when it offers something that suits my needs. I'm not one of these either/or do-or-die fanatics. I buy whatever can work for me at a fair price.
