Samsung Galaxy S4: How to Fix Can't Enable Anti Shake in the Camera App in Android 4.4 Kitkat

By default, the Volume key is assigned as the zoom key in the Camera app, but after this phone updated to Android 4.3 Jelly Bean you can assign the Volume key as the camera key or the record key. Surely it'll be useful for those of users who want to be able to take pictures or record videos by using the physical button or for those of users who have difficulty to take pictures using the on-screen button, for instance those users who like diving where taking pictures using the physical button is easier to do while the phone is using waterproof case.

As a note, using the physical key as the camera key will increase shake and it makes the picture become unfocused. So, aside from holding the phone as steady as possible when taking pictures, you can also turn on anti shake to reduce shake and help focus when the camera is moving. A few days back, an insider asked me why the anti shake option in her phone was grayed out so that she couldn't use it. After did some investigations, it turns out that the anti shake option will automatically be disabled when the auto night detection is enabled. So, when you experience this problem, you have to turn off the auto night detection to make you able to use the anti shake option.

How to fix anti shake option is grayed out in the Camera app?
Below are the steps to do so:

1. Open the Camera app.
2. Tap the Menu key and then select Settings.
3. Under the Camera tab, scroll down, tap Auto night detection and then select Off to disable this option.
4. Now, the anti shake option should be available.
5. To enable Anti shake, tap Anti shake and then select On.

Because the auto night detection must be disabled when you want to use anti shake, then if in the certain condition you need to set the Volume key as the shutter key but you're in the low-light condition, then you can compensate the lack of light by turning on flash.
