TheIt does not have a 3D Touch and, therefore, not some of its benefits, such as extending notifications for displaying more content, but will change through future software updates.
iOS 12.1.1, currently in beta, will get users in the coming weeks and enable iPhone KSR a long push to notice to show more information, actions that will work similar to the same long-press action, but on the phones with 3D touch on the screen.
If you do not have a 3D touch, iPhone KSR loses functions by pressing on the screen to display submenus in icons, display more information in notifications, or view images and videos. Apple did not put the necessary 3D Touch membrane as a way to lower the cost of production of KSR and sell the mobile phone at the lowest possible price.
Page 9to5Mac has discovered that iOS 12.1.1 is activated by long-press software on the iPhone KSR. On the site it is added that it is a little strange that Apple has not added this since the first version of iOS 12, considering that iPads do not have 3D Touch on the screen and have the function of displaying more content during long print.
The difference between the Haptic Touch (on the iPhone KSR) and the 3D Touch is the response time. Thanks to this state-of-the-art technology, the phone immediately responds by recognizing the increase in pressure on the screen; while with the Haptic Touch system it is easy to react.
