It’s a little late, you know?
I owned 7 SE 2016 from day one, April 5, 2016.
It wasn't a cheap phone, it was a 6s in the body of a 5s, but people didn't understand it, most of them didn't understand someone who paid the same price for an older phone, so they began to believe it was a cheap phone, not the last ergonomic iPhone ever made.
SE 16 in my experience has two main bugs: the first six (with two warranty screen replacements), until the last one was changed to warranty on April 5, 2018, it had the defective Home button, it became shaky and noisy after 3 weeks, even if not used.
The upper rear glass, on every SE 16 I owned, was flush with the body but in a few weeks of use, especially with high CPU temperatures (games and GPS localisation), the angle of the upper glass (sometimes both) rose.
What I can understand about these two bugs is that the Indian factories that assembled SE 16 were not skilful enough and Apple's quality control on this product was incredibly poor; the project was wrong, A9 was too much for the 5s body, but it allowed years of use despite the ever-increasing iOS bug.
5/5s were pretty good if you didn't update them (I have a 5s with iOS 8 and it's even more useable than iOS 15 on SE 16, faster and less heavy for the battery, which is 9 years against 18 months of that of the SE 16 but lasts 10 times longer); 4S was the best iPhone ever made for older generations (indestructible like a Nokia 3310, with a stainless steel body, better designed than the 5 and all subsequent iPhones with its system of coupling the front and rear panels to the centre body).
I own a 13 mini 512gb to replace the SE 16 for 2 weeks, just because I don't want a huge phone (14 and above) and the battery consumption of SE 16 is pathetic from iOS 13.
It's a little harder to handle with one hand (hands as small as mine), but it's pretty good.
It has only one small problem: it gets hot as the SE 16 in charging and games/locations/music and video synchronisation.
6 years to produce it, at the double price.
Apple got worse day after day, I already knew it but I could deeply understand how much it got worse only by seeing first-hand the poor quality of the projects that deliberates and sells.
