Q: Disable calculator clicks in iOS 10

The clicks seem to be controlled by the ringtone settings. Using the Mute Button will work, whereas reducing the volume might also reduce the ringtone volume.

Maybe we should use the feedback link to get the click sound of the calculator silenced again in a future iOS update:

Apple - iPhone - Feedback

One reason I mentioned the link

I have the same problem.

I just applied 10.0.2 and the clicks are still there in calculator and others applications

Why would you expect an update whose only purpose is to fix a bug in headset controls to accomplish anything else?

It is in very poor taste to spam ASC as you have been for the past few hours.

Strange...!

I updated to 10.0.2 and it solved the problem on my iPhone 5SE...

Update did not change it for me either.  I  have keyboard clicks turned off on the iPhone. So, I don't know why calculator is all of a sudden making keyboard clicks. It isn't very loud, but noticeable.

I Find this incredibly annoying also.  Not only in the calculator, but also when using the wheel to select dates and time in  the alarm and calendar apps. Disabling keyboard clicks used to silence all of these And it's frustrating that they no longer do.
