How to prevent iPhone from vibrating during calls? I can't figure out how to prevent my iPhone SE (iOS 10.2) from vibrating when messages arrive while I'm on a call (that is, it vibrates right into my ear). This happens regularly, and I'm sure it occurs with other models/software versions.

I cannot find any setting regulating this, therefore it looks like a major bug: it doesn't have any function and interferes with the normal phone usage.

Does anybody know if anything has been/is being done with respect to this issue?
I believe you need to look in Settings > Sounds &amp; Haptics. 

In there you have various settings for Sound and Vibrate. Under the section "Sounds and Vibration Patterns" there's a "Text Tone" option. If you touch that, you have options for what happens when you receive a Text, both Sound and Haptics. One of the options for Haptics is "None"
