Only Apple can price their phone and people still buy.
Their app store and OS are very proprietary. Recent hackers that stole CPF money with malwares succeed on Android phones. Android phones have three ecologies within; google, phone maker and telco. Either one, eg. phone maker can have loopholes (intentional or not). Given the same processor speed, apple platform should be faster.
Apple is very integrated and more anal, basically you cannot even install add-ons to their browsers. For example, i shared that in South Korea, their banks require security add-ons to be added to the browsers on their laptops to view bank accounts. Therefore their clients can't do internet banking on safari browser and got to depend on apps from Apple Store (safer).
Of course, Apple getting damn ex, so SOS getting Samsung economy-class A series. Samsung has the best encryption, sometimes better than Apple.
