Many iPhone and iPad users have been complaining that their volume controls are no longer accessible by swiping up after upgrading to iOS 10.
Although this is partly true, it isn’t entirely.
The controls are still available but they have been moved around slightly.
To access volume controls in iOS 10, users must first swipe up and then swipe right to left.
After performing this second swipe, the volume controls should be visible as they were before iOS 10.
Unfortunately there is no way around this new feature without jailbreaking your iPhone.
