I bought an iPhone 4S way back when because I wanted a dead-simple UI for my mom.
Now she's on an iPhone SE (3rd gen), and the UI is a complete shitshow.
F you Apple.
(She also does not want a newer (aka larger) iPhone because they will not fit in her woman's jeans which notoriously have small pockets. Another "F you" from Apple to the consumers.)
If consumers cared about small phones Apple would still make the mini series. It's hardly Apple's fault the biggest phones are the most popular. In fact, they were late to the larger phone sizes, as the iPhone 6 shipped years after Android started going big.
