Xperia Z3 :: Quick Camera Button Sets The Camera In Automatic Settings

A friend is having troubles with his Z3 : He used to take pictures with the quick camera launch button, but since a recent camera or system update, when he use this button, the camera is set to automatic mode instead of manual, with poor resolution and quality settings. If he launches the camera with the standard button from the phone menu, everything is fine and perfectly set up.

When the camera is used from the quick button and set back to the correct quality settings and manual mode, after closing it, it goes back to auto mode with bad settings. Same thing when he slides the camera icon from the locked screen. The only way to get the proper settings when launching the camera is to use the icon from the phone's menu.

He tried a lot of things, from uninstalling the camera updates to searching everywhere on the internet, there is no information or messages about this problem.
