Does Huawei Honor support silent camera mode in Ice Cream Sandwich? I use the app Camera Zoom FX for taking photos. On Gingerbread, I was able to mute its sounds via the settings. After updating to Ice Cream Sandwich, I always hear a sound when taking a photo.

Since I updated the app too, I was wondering: Is this a bug in Camera Zoom FX or doesn't ICS for Huawei Honor allow to mute its camera?
No, your phone needs to be rooted ( as confirmed by the developers ). You may want to try Camera ICS + however which has as many features but remains silent.
