Q: How cn I take just one picture at a time w/ iPhone 6. Always shoots multiples.

Tap the button once only, make the contact as brief as you can.

I know it is not easy, I am younger than you but post stroke, and my fingers have lost feeling, but it is possible.

In Settings > General > Accessibility, you'll find some settings that may help.

Look under Touch Accommodations and Hold Duration.

Maybe I should try it

And maybe LACallen deserves a helpful more, you can give 2

Glad to hear.

You helped both of us, I never needed to look there before now

I should be awarding you the Solved badge

My pleasure.

That's what we do here right?

We try.

I hear ya.
