it's usually the same story 95% of the time. some person has been using the newest iPhone for 10 years updating every year and then they go to try Android and they pick some budget 4 year old android that has never been good so they say android sucks and moves back to apple.
or the same story above and they pick a flagship but are so engraved in imessage and apple ecosystem they never truly give the flagship android phone a chance and return it in the 15 day window.
for me it's the opposite, I've always had verizon so the first 3 iPhone weren't available I got used to flagship Motorola Droid and their 24-48 hour battery life LTE phones, and remind you this is 2010ish when LTE was first being rolled out so everything LTE sucked ie the thunderbolt phone which supposedly only got 2 hours screen time. sure I got the iPhone 5S on release as a second phone, went back to droid, got the iPhone 7 on release, went back to droid because the public found out apple was throttling the phone through battery health. so I've basically been hopping and skipping back and forth flagship samsung to the latest iPhone upgrading every year
now I'm on the s23 ultra, and my iPhone 14 Pro Max sits on the desk. I can't imagine going back to iPhone with this current iteration, I can plug a USB storage into my phone and do a backup any time, my information isn't stored in the cloud and it's secure.
oh yea the third type of person, always bought the budget android for $50 on sale and has delt with plagued 5 year inferior hardware that'd be laggy. then decides it's finally time to spend $1,500 on an iPhone and thinks it's world better, zero lag, now an iPhone user for life. when in theory if they would have spent the same money on a flagship android they would have never given iPhone a second glance.
