Now that the iPhone SE has been delivered, some owners are noticing that Haptic Touch isn't working in the Notification Center. Previous iPhone models used a long press to allow direct interaction with a notification, without launching the associated app. Haptic Touch works much the same as 3D Touch, which on older models actually detected pressure on the screen.
Update: You can now delete all third-party and select stock apps by using a "hard press." To delete an app, just press down on the app icon to open the pop up menu. Tap the "Delete App" tab, then confirm to remove the app from your device. This has replaced the original hold and wiggle technique to delete apps from an iOS device.
Setting up a new iPhone with iCloud backup? Have a ton of apps waiting to be updated in the App Store? There's a 3D Touch shortcut for that. A few taps can tell iOS which apps are the most important, so you can get back to using them more quickly. For starters, all pending app updates can be installed with one deep press on the App Store icon.
For iPhone, Pad, and iPod touch owners with many apps installed, it seems there's a never ending stream of updates pushed by developers. Most of these updates come in the form of minor bug fixes and improvements, with a constant nagging red notification bubble on the App Store icon. Just opening the App Store to see what's available under the Updates tab takes up valuable time.
Quickly enabling Do Not Disturb is a key feature of the iOS Control Center. Apple has added more flexibility over the years, with options to temporarily switch on Do Not Disturb and deactivate it automatically. Do Not Disturb can be set to disable itself after an ongoing Calendar event, when the user leaves a specific location, and more.
