that’s interesting,
I didn’t want IOS because the SCOS app isn’t avaible but if it is like You describe the way You use normal camera is even better then xd
So You open camera app and set whether You want to take photos or videos and then You tap the screen 3 times with 3 fingers so You have black screen and You can take photos with volume up button or launch and stop videeo recording? or it works only with photos and You have to launch video recording before You put the black screen on?
