If you are having issues with using the 3D Touch on your iPhone 6s, iPhone 6s Plus, iPhone 7 or iPhone 7 Plus, then you can try changing the sensitivity level of the screen's retina.
The fact is that the 3D Touch sensitivity level on your phone needs adjustment, if you're having difficulty in getting a response whenever you poke and push hard on the screen. The good news is, the process is simple and only involves making a quick to the 3D Touch settings in iOS' settings menu.
How to change 3D Touch sensitivity on your iPhone
- Open up your iPhone's settings (by tapping the desktop icon).
- Tap on the General settings option.
- Scroll down to Accessibility and tap on it.
- Somewhere down the Accessibility settings menu, you should see 3D Touch listed.
- If you want to disable or enable 3D Touch, you can tap the slider button. If you see green, that means 3D Touch is switched on.

To adjust your iPhone screen's sensitivity, tap 3D Touch and a sensitivity bar will come up. You have the option of choosing between light, medium and firm. So if you find that 3D Touch simply isn't working for you or it takes too hard a prod, try changing to light.
There's a photo that you can use to test the new settings beneath the sensitivity bar. If done correctly, you should see the photo pop up to fill the screen when you give it a long press. Else, you'll need to manipulate the sensitivity settings some more.
