3D touch on iPhones responds to pressure applied to the screen. The screen can tell when you tap it and when you apply pressure to as you would to a physical button. Of course, the screen is a grid of icons and not actual mechanical buttons. With mechanical buttons, you don’t have to worry about how hard you tap the keys. With 3D touch, things are different. The screen is sensitive and it might be too sensitive for someone who is heavy handed. Here’s how you can mange 3D touch sensitivity on your iPhone.
To manage 3D touch sensitivity on your iPhone, open the Settings app. Go to General>Accessibility>3D Touch. At the very top is a switch that you can flip to turn the feature off. If you don’t find 3D touch useful, you don’t have to keep it around. Turning 3D touch off also turns live photos off.
To manage 3D touch sensitivity, scroll just a bit further and use the 3D Touch Sensitivity slider to manage it. Below the slider is an image that you can tap to test how the new sensitivity feels.
If you are very heavy handed, you should move the slider towards the ‘Firm’ end. If you have a more gentle touch and feel 3D touch doesn’t respond as well to you, move the slider towards the ‘Light’ end.
Use the sample image to test the new sensitivity out. Bear in mind that 3D touch has two pressure sensitivities; pop and peak. Both are controlled via this sensitivity bar and both can be tested on the sample image under the setting.
For devices that have gained 3D touch through the use of jailbreak tweak, this option may or may not be present in the Settings app. If it is, then it should allow you to manage 3D touch sensitivity. If it is absent and the jailbreak tweak doesn’t have a setting for it either, you might be out of luck.
