I'm going back to my original 2016 SE. 12 Mini is still too big. It's manageable, but not enjoyable. I find that I still need to reach for the top and reposition the Mini in my hand. Something I don't have to do with the SE.
I was very excited to get the Mini. In fact, it was the first phone since Iphone 5 (the original one, not the S with the stupid flat IOS7) that I was excited to get.
I really hoped that I could fall in love with it. Didn't happen.
I still use my IOS6 iPhone 5 as my alarm clock and put up with my SE as my main phone.
I use a Huawei P30 for the camera which is still miles better than Mini 12's camera.
Plus I hate the glass back and strongly dislike the lack of a physical button.
All of it I guess I could get used to but at the end of the day, I don't see a point in switching.
Just ordered a new high capacity battery for my SE.
It will serve me for another year or two—and then if too many apps stop working with the new IOSes that will not be available for the SE (or if Apple releases a Mini-Mini), I'll switch.
