Control Panel is the same on an iPhne, accessed by swiping up from the bottom of the screen, while double clicking the Home button brings up the app switcher. on the iPad they used to be together on the same screen, but in iOS 12 they have been separated. Swiping up or double clicking the Home button displays the app switcher, while swiping down from the top right portion of the screen displays Control Panel. Swiping down from the middle or left top displays the Notification Center on both devices as it did in iOS 11. Another year, another iOS! iOS 12 showed up on iPhones and iPads Monday, and, as usual, I was quick to upgrade. Apple claims "iOS 12 is designed to make your iPhone and iPad experience even faster, more responsive, and more delightful." So I was anxious to see how fast my phone and pad would become, and how delighted I would actually be. The new operating system is compatible with phones going back to the 5s and the iPad Air, so my iPhone 6 Plus and iPad mini are both compatible, and even with the 6th generation iPod Touch.
Some upgrades are so stunningly different that it feels like you have gotten a new device, even though you haven't. That certainly raises the delight level. But most iOS upgrades are less obvious, also a good thing because it means that for the most part you have no learning curve, so can continue to be productive without pause. Less delightful, but, in the big picture it is what I have come to like best.
