I use iPhone 14 Pro Max. Before that was the 12 equivalent then before that was a Samsung Galaxy S10+. I loved the freedom Android gives with customisation and personalisation. But I decided to go back because having an iPhone 5s as my first phone, it's a no-brainer really. It does what I want it to do, simple, easy to navigate and heavy on the privacy and security.
I appreciate both Android and iOS, they have their own advantages and disadvantages but I am happy and there's no reason to change something when you're comfortable with what you've got. Though the Galaxy phone was an interesting experience.
