I'm not sure if it works on non Asus devices (I don't have one to test, sorry), but the Asus PixelMaster Camera has a manual mode with sliders for basically everything, including white balance.
I mean when you long press the app from the app drawer, it brings up "app info" and "uninstall". Go to "app info" and then wipe data. Then reboot. As for updating it, I think you should uninstall if possible, and then reinstall the camera app: https://play.google.com/store/apps/details?id=com.asus.camera&hl=en
ASUS PixelMaster Camera does it with the smart remove feature but it only takes 5 photos to try removing "moving objects".
