Delete the connection in the phone settings. Only connect the controller in the Breeze Cam app.
I am assuming you are referring to the modified Android version of BreezeCam. What color is the icon for the app? If red (v1.4.7.3), some had issues with the controller not connecting. You can try the one with a green icon (v1.4.7.4). Either can be downloaded here

This is only for Android and the authors of the cloned app advise to uninstall the official version of the app. Having both on the phone/tablet can lead to unexpected issues with the Drone Settings. Also make sure you have the controller set to the proper mode Power+A for Android or Power+Y for iOS.
If you have a modified version of BreezeCam for iOS we could use that along with instructions for installing.
