All iPhones starting with the iPhone 6s (with the exception of the first-generation iPhone SE and iPhone XR) had this feature. Starting in 2019 however, 3D Touch was omitted on all iPhones starting with the iPhone 11/iPhone 11 Pro, and its software features were removed from iOS 13 and later in favour of Haptic Touch. Haptic Touch retains much of the functionality of 3D Touch but cannot detect pressure, as the display lacks integrated capacitive sensors. Actions that previously required a deep press now only require a long press, and the haptic feedback is no longer associated with the applied pressure but rather the touch duration. Due to the migration from 3D Touch to Haptic Touch, all iPad models that can update to iPadOS 13, along with the first-generation iPhone SE and seventh-generation iPod touch, which previously did not support 3D Touch, gained similar Haptic Touch functionality with the iOS 13 and iPadOS 13 updates, although without any haptic feedback.
