Anders_ASUSdoes by saying that you really need to up your game with the camera department. coz stock asus camera is losing it's value color is pretty much wash out. and the filter you are saying is built in the ASUS Camera APP
The side effect of allowing this would be that the ROG watermark could lose its value. It doesn't just say that this photo was captured using an ROG Phone II. It also says that this picture has been captured using asus camera app without any filters.
We want the watermark to stand for something so the answer will be no. We will not include it in the gallery app
