How to Fix 3D Touch Not Working Issue on iPhone 6s/6s Plus
Make sure 3D Touch is turned ON
Before going furiously on Apple about delivering you a faulty iPhone, make sure you have the 3D Touch turned on. In order to do so, go to
Step #1. Tap on Settings → General.
Step #2. Tap on Accessibility scroll down to 3D Touch.
Step #3. Turn 3D Touch.
Press it hard enough
All of us are afraid to break our iPhone 6s/6s Plus screen while pressing it hard. But don't worry; it's hard enough for your fingers to break it. Most of the users are making the same mistake by pressing the screen lightly. Try placing your iPhone 6s on a table and press the app with pressure. You'll see a 3D Touch popup coming up. If it doesn't, you can check other possible fixes below.
You can adjust 3D Touch sensitivity to comfort yourself. Having light sensitivity will invoke 3D Touch more easily than having it Firm. In order to change it, go to Settings → General → Accessibility → 3D Touch. Tap and drag the slider to Light or Medium according to your comfort level.
Press and hold, don't drag
Make sure your finger doesn't slip on the screen, which will result in tap and hold function and not 3D Touch. Press the app hard enough with still fingers and check if 3D touch is working.
Reset all settings
Out of many users on Apple forums, some of them suggested resetting all settings. By doing so, they were able to resolve 3D Touch issues. Resetting settings will not delete any of your data. It will just reset all the settings to factory state.
Go to Settings → General → Reset → Reset All Settings and enter passcode to confirm.
Start from scratch
I hate it when I write this. It's really annoying to reset everything and start from scratch on an iPhone. This is an ultimate option to resolve this issue. Head to Settings → General → Reset → Erase All Content and Settings and enter passcode to confirm. Before restoring from backup check if 3D Touch is working. If it is working you can restore from the backup.
After doing all this and ending up with no result, then the last option is to book an appointment with Apple and check if your hardware is faulty.
