In my opinion, in general, unsafe (outdated) devices should not be used as they are a huge attack vector because there are so many of them.
Same goes for my SO's Galaxy Ace 4 Style, which she left lying there for an iPhone SE, but might return to the Samsung because the iPhone, while being a great device overall, will now require a battery replacement procedure because it wasn't designed for doing that at home and the battery is very much dead.
My Galaxy S8 is humming along nicely even though I subject it to a lot of environmental stress daily by e.g. showering with it in hand.
Bottom line is iPhones aren't that special in this regard anymore.
lol
half the people in the third world use their phones for 5+ years
Maybe some budged non-flagship Android. You ought to compare iPhones to flagship Android devices. Because iPhone is a flagship device. Don't spread misinformation.
