UneasySilence has uncovered a hidden feature in tap tap tap’s Camera+ iPhone photography app that allows users to control the camera shutter using the iPhone volume controls. Tap tap tap had originally planned to include this feature in the most recent update to Camera+, however the update was rejected by Apple for using “iPhone volume buttons in a non-standard way, potentially resulting in user confusion.” Tap tap tap reports that it spoke with Apple at some length about this and were informed that “overriding the volume controls is one of the most common reasons for app rejection” and that other camera apps that make use of the volume buttons likely “slipped through the review cracks” due to developers intentionally hiding the feature during submission. Tap tap tap was ultimately forced to resubmit its Camera+ update to the App Store without the hardware shutter control feature enabled.
As UneasySilence reports, however, the feature is still present in the app and can be enabled by entering a simple URL in Safari on the iPhone. To enable the volume buttons to be used as shutter controls within Camera+ users can open Safari and enter camplus://enablevolumesnap into the address bar. The feature can be similarly disabled by entering camplus://disablevolumesnap in the Safari address bar.
It is unclear at this time what Apple’s response will be, if any, to this feature still being available within the app. Camera+ is available on the App Store for $2.
Update: Camera+ is no longer available on the App Store. There has been no official word from Apple or Tap tap tap as to why the app was removed.
