Article for context:https://www.theverge.com/2023/9/12/23870522/iphone-15-pro-max-thread-smartphones (Ik that I am talking about multiple companies when I refer to android companies but many singular companies make more innovations in the phone space compared to apple)
It's only 4 years old. There are still plenty of people using 7 year old iphones
That said, the 7 Pro was cool and I loved it, till I realized I couldn't use my bank app is I wanted a custom rom so I just gave it to my mom and got an iPhone because if I can't tinker, I don't want a platform that needs tinkering to get it just right lol
