The iPhone 4S does not possess the ability to detect faces while shooting video, unlike the iPhone 5 and 5th generation iPod Touch. The good news is however, if you have been wanting this functionality, you don’t have to upgrade.

Thanks to the Evasi0n iOS 6.x Jailbreak, there is a Cydia tweak that can enable face detection on the iPhone 4S called FaceDetectionVideo4S. The official description for this Cydia tweak is as follows “enable face detection in video preview like iPhone 5 and iPod Touch 5th generation in iPhone 4S only.”

I do not have an iPhone 4S so I have not been able to test this Cydia tweak, but I have heard many reports that it functions as advertised. If you are interested in the FaceDetectionVideo4S Cydia tweak you will be glad to know it is being offered for free in the BigBoss repo.

How To Enable Face Detection When Shooting Video On iPhone 4S

We have covered quite a few other Cydia tweaks that enable functionality that newer devices possess, but are still capable of being offered on older hardware. Examples of these tweaks range from LLBiPT5 to Still Capture Enabler.
