Camera, Music, And Video - Huawei P8 Faq

4.1 Why is the DTS effect not obvious?
Use a headset for better sound effect when you are playing songs.
4.2 Why can't I view photos I have taken before after I
open the camera by double pressing the volume down
button?
You may have set a security lock for your screen, which prevents you from viewing the
photos you have taken for the purpose of privacy protection.
4.3 Can I disable the shutter sound for snapshots?
Yes if you have turned off the shutter sound for normal photo shooting in Settings.
4.4 How do I enable the snapshot function?
Consecutively press the volume down button twice when your screen is turned off or locked.
Make sure the interval between the two presses doesn't exceed 500 ms (0.5s).
4.5 Why can I only view the current photo after I have set
the security lock for my screen?
You may have set a security lock for your screen, which prevents you from viewing the
