I had Android phones before and they remind me so much of Windows and just how slow Windows is - my work computer has worked faster than the Androids I've had before. iOS is just smooth, no matter what you're trying to do. I'm a huge privacy nerd, too, which is why I love iOS. A friend of mine was able to hack into his whole families phones and read all of their text messages and control the phone - this was on one of the new Samsung Galaxy's running Android 10.0.
Another reason why I love iOS, I can actually update my phone whenever I want.
