Whenever take a photo using my selfie stick (Anker), which recognizes as a Bluetooth keyboard, the second press of the button results in some action other than taking another another photo. I might want to take three in a row, but instead I get one photo, and then the next time I press it, I get either photo review/edit or sometimes Share. I have checked all the Camera settings and see nothing about it, and the Bluetooth keyboard is set to English US. Any other ideas what to check?

Obviously the selfie stick really just emulates a volume button. But when I tap volume, it behaves normally and takes multiple pictures in sequence.

I have searched but I'm on vacation and o ly have my phone. That limits things, as I expect you know. Thanks.
