How to adjust the 3D Touch sensitivity on the Apple iPhone 6s and iPhone 6s Plus
Although an increasing number of people vehemently claim that Apple stopped bringing true innovation to the market a few years ago, the truth is that Apple's new pressure-sensing display technology opens the way to a new user input dimension.
Debuted this past Spring on the Apple Watch and inherited by the new iPhone 6s series, the 3D Touch system can recognize between a tap, a press, and a hard press. A growing number of iOS apps are now being optimized for pressure-sensitive displays, as app devs both big and small make use of the new hardware to allow for more complex user interaction.
Step 1. Go to the Settings app on your Apple iPhone 6s or iPhone 6s Plus.
Step 2. Go to General -> Accessibility.
Apple conveniently includes small test button. Play with the settings until you're comfortable with the sensitivity of the 3D Touch feature.
Step 5 (Optional). If you don't want to use the 3D Touch system, you can turn off the feature by flipping the 3D Touch switch to the right.
There you go, now you can adjust the 3D Touch sensitivity, or even turn down the feature if you find the extra input dimension to be a bit confusing.
