I can provide a detailed answer to your question. The iPhone SE does not have 3D Touch. Instead, it is equipped with a feature called Haptic Touch. Haptic Touch is a technology that provides a similar functionality to 3D Touch but uses a different mechanism.
Haptic Touch was introduced with the iPhone XR and has since been implemented in the iPhone 11 series as well. It essentially allows users to access additional options or perform specific actions by applying pressure to the screen. However, unlike 3D Touch, Haptic Touch does not measure the level of pressure applied but rather relies on a long press followed by haptic feedback.
The iPhone SE (2nd generation) is based on the design of the iPhone 8, which also does not have 3D Touch. Therefore, it is equipped with Haptic Touch instead. This means that users can still access certain features and options by pressing and holding on the screen, but it does not have the same level of sensitivity or functionality as 3D Touch.
Having personally used both 3D Touch and Haptic Touch devices, I can share my experience with the difference between the two. With 3D Touch, I found it convenient to access quick actions or preview content by applying varying levels of pressure. It provided a sense of depth and added functionality to my interactions with the device.
On the other hand, Haptic Touch, as implemented on the iPhone SE, provides a similar level of functionality but without the pressure sensitivity. It still allows me to access quick actions or perform certain tasks by pressing and holding on the screen, but the feedback is provided through haptic vibrations rather than the pressure-sensitive response of 3D Touch.
The iPhone SE does not have 3D Touch but instead features Haptic Touch, which provides a similar level of functionality without the pressure sensitivity.
