Apple - What is the quickest way to unmute the phone app on a locked iPhone?

I've struggled with the same for years--and just discovered an easier way. Tap the home or power button to get to the lock screen, or on the iPhone 6s or 7 just pick the phone up so the screen "wakes up".

You'll see the phone number you're dialed into and the current call time in mm:ss at the top of the screen. TAP THE PHONE NUMBER and you'll get the mute/keypad/speaker/add call screen, all without unlocking the phone.

There is no "good" answer for this, but here's the best I can figure out.

Once you are on the call and muted:

• make sure you are on the screen that displays the mute/addcall/facetime/contacts buttons (I'll call this the "mute screen" from hereonout)

• click the top button that turns off and locks the phone

• when you need to unmute, you can click the on/off or home button and swipe right. at this point you will see the "mute screen" and you can unmute.

• this only works once as far as I can tell. Once you have done this once, the next time the phone locks and you need to unmute, swiping right will not display the mute screen, but will just display your passcode pad as usual.

NOTE: in order for this to work at all, the screen MUST BE the mute screen when you click the top on/off button. If you are on any other screen when the phone locks, this will not work even one time, as far as I can tell.

I hope this is helpful. As usual with Apple, basic functionality is omitted for no discernible reason. "YOU AREN'T I-TELEPHONING RIGHT."
