Switching from Apple to Samsung

Hello all! I am looking for the best place to really ask about what this experience may be like. For as long as I’ve had a cellular device, I have had various Apple iPhones. Currently, w/ T-Mobile as a carrier I have a completely owned pink iPhone 15 (128GB). I have been considering trading this device in for a Samsung Galaxy S26 256gb device. Now I am super nervous. Leaving the Apple ecosystem to be honest, but I feel as if they have left me no choice. My phone is now overheating greatly (when I first got the device I had to get this fixed at the Apple Store) and is dying super quickly. I absolutely hate this turnover as new devices come out. I have concerns with the email I’ve had for many years, iCloud storage transfer, Apple Music, etc. -If you have made the switch before, what was it like for you? -Will T-Mobile aid in the transfer of data? How does that work? -Should I consider a different phone (Also looking at galaxy Z flip 8)? *Also hoping the switch will help me get less comfortable with my personal phone. In a way I have become heavily reliant on my device to which I spend too many hours a day on. The uncomfortable nature of an unfamiliar phone might make my movements more intentional.
