Hi
I'm the developer of the app - thank you for pointing out those shortcomings. I also have the Icon, and incidentally I also use LockMix as my only lockscreen app, and I haven't experienced the problem you mention with locking the screen. Do you unlock the phone some time before using the Band Camera Control? In the Speech settings, have you enabled the 'Allow Speech above lock'?
I didn't know that it saved pictures to the root folder! I've just checked the gallery app on the phone and thought that was good enough

I will fix that.
I will add a feature to use the front facing camera using an extra keyword in the command, e.g., 'take a photo [front facing]' with the keyword being optional, what do you think?
I'll make it faster, I've thought of that too
Thanks for the feedback,
Jens
