Device Sensor Issues

Device sensor issues include problems with the mobile device’s camera, microphone, and geolocation.
Issue Solution
The mobile device’s camera doesn’t work in child browser windows for input fields. Instead, users see a black screen. This issue is probably a bug with Apple's SFSafariViewController, which is used for child browser windows. This issue is exclusive to Salesforce for iOS. Open the Salesforce in the Safari mobile browser by tapping the Safari icon in the lower right corner of the child browser window in the Salesforce mobile app.
