iMessage and FaceTime. That’s it. Literally. My group friend moved to Signal/WhatsApp. So we chat and video chat on those platforms. It’s just the people outside of the group that becomes an annoyance. Android is superior in every other way.
I have an iPhone 15 Pro for work, my personal phone is a Galaxy S23/23 Ultra.
It’s like a stock. Perception of value. Once the dominance iMessage is removed, you’ll see iPhone values begin to drop. It’s the beginning of the end of iPhones. Which is why they removed the SIM tray. Removing a slight amount of freedom. Just slight, in case people want to be curious with Android on the whim.
