Assignment: iOS or Android

On my own preference and perspective, iOs and Android have both beneficial and disadvantages. iOS provides better security and privacy. The system does not lag from the previous updates it has. Moreover, it has closed source  references, with this file transfer has a complicated approach preferably if it is not compatible to android users. On the other hand, Android has an open source with high compatibility to various operating systems and users.  It offers affordable and mostly free services and storage.
