One of the primary reasons why a majority of people still prefer using iOS over Android is software updates.
For instance, the iPhone 5S that was launched in 2013 came with iOS 7.
Surprisingly, the smartphone was supported for five years and the last update it received was iOS 12.
On the other hand, mid-range Samsung smartphones receive quarterly security updates.
Samsung will still follow the exact same pattern for offering security updates.
So these are the devices that will receive four years of security updates.
In addition to security updates, Samsung generally offers three major software updates for a majority of Galaxy devices.
