My ReSound Omnia controls when I bring up the Accessibility hearing settings:
I don’t “triple-click” my right iPhone power button. I’m always loathe to test the mechanical durability of buttons on my phone. I swipe down from the top on the very right side of my phone. That brings up the iPhone Control Center. I have installed the Hearing widget (Settings, Control Center, add the widget there if you don’t have it already). Here’s my Control Center screen and the Hearing widget is in the lower left of the screen (the EAR symbol). Tapping it opens the controls shown in the first screen capture of this post.
BTW, the “Battery 100%” is the level of my zinc-air size 13 batteries in my Omnias, not the level of my iPhone SOC. Jay is likely using zinc-air batteries, too, since he’s also at 100% in his screenshot two posts above!
