"I've never heard a negative thing from an apple customer"
People return/sell off their iPhone's in my country(India) because it has-
No SD slot
No fm
No file manager
No Bluetooth ftp(since no file manager)
No text prediction
Small screen
No NFC
No glance/notification led
Mediocre camera for the price
No USB MTP
No micro USB
No removable battery, and short battery life as compared to other phones for the same price.
I don't understand what you are paying for in an iPhone. Even my Nokia dumb phone has a file manager, SD slot, micro USB,fm. Apple can't put a $1 fm chip in a 700$ phone? Ridiculous. No wonder they are declining YoY.
iPhone market share is close to zero in India.
