I’ve just upgraded my iPhone 4 to iOS 5 and was looking for the “Access from Lock screen” feature as it didn’t show up automatically. I was afraid that the feature would not be enabled on the iPhone 4… After a long digging process in the preferences and a quick look on the Internet, I found that the feature was enabled using the “Home” button.
In fact, it’s quite easy to use:
- With your locked iPhone, double-click the “Home” button ;
- Tap the camera icon that appears ;
- Take you photo!
Note that you can take the photo using the “Volume UP” (“+”) button.
