#The question is about ios
Recently our company began patenting a new iphone case and we got an idea of making an application that interacts with the proximity sensor and switches off the screen, while something is infront of the phone, as it does the telephone app, voip apps and this one: https://itunes.apple.com/us/app/hardware-tools/id493206334?mt=8
But the main problem is that we want it to interact with sensor in background, too. Shazam, Dictophone and xRec ( https://www.appaddict.org/view.php?trackid=670777247
) apps use microphone in background and xRec even records the screen in that condition, so we still hope that it can be possible. May be there is possibility to make this app a voip or tracking position program and add this "side effect" of proximity in background?
Thank you in advance.
