Some jailbreak tweaks are purely cosmetic, and ClassicShutterAnimation falls squarely into this category. Anyone who misses the skeuomorphic design of iOS 6 will remember how Apple animated the Camera app. With every shutter release, fake aperture diaphragm blades appeared signaling the photo was captured. While this may have been charming, the animation was abandoned in 2013 with the release of iOS 7.
Once installed, there are no settings or options to configure. Simply open the Camera app and snap a photo. The tweak only displays the animation in standard PHOTO mode, using SQUARE or other photo modes will show the normal shutter release featured in iOS 7 and later. ClassicShutterAnimation may feel like it slows things down, but then it's supposed to be nostalgic.
ClassicShutterAnimation is free on the Cydia app store. To start customizing iOS, click here for instructions on how to jailbreak iOS 9 with Pangu. Find out how to purchase and install Cydia tweaks with this guide.
