This isn’t news.
Teens want what’s best and a nice decent experience and apple provides that. And why most people like them not even the “best “ aspect
It’s the fact that iOS almost rarely lags, and just works. Fluid OS and security updates and the fact your phone will get updates for sure for 5-6 years vs most androids manufacturers drop even there most expensive model after just 2-3 years. And let’s not even talk about the mid range they’ll get supported for maybe a year if your truly lucky. I’m speaking from experience owning multiple androids from middle school
Into high school and adult life and now I have an iPhone. This se 2 has lasted me about 4 years almost now
They just work for all age groups and the added benefit of having major os updates for 6 years guaranteed instead of android which even the expensive models are lucky to see even more than 2 years of android updates
