I have used Samsung s8, s21 Ultra and s23ultra which got stolen and loved. I see where the iPhone 16 pro max has a large screen and rates better than s24 and s25 ultras. Not happy with where these phones are headed, s23ultra was awesome. How hard is it to go from Android to iPhone, especially learning system and functions. I prefer Android but the s23ultra would be the only one I would want, possibly s24ultra. Need advise from those who have switched.
