Huh, this might make me finally install Magisk.Just for your information, you might have missed that, another developer going by the name of ArtZ did something similar, just for a regular apk ( https://www.celsoazevedo.com/files/a...mera/dev-artz/ ). He developed for the LG G6 which shares the IMX 258 with the PH-1 and very much focused on color reproduction. I've been using his latest apk since its release and always returned to it when testing other ones in between since the color reproduction is much better in HDR+ enhanced compared to other apks, his settings might be of interest to you as well in your development.Edit: after testing tolyans build with your settings I'm definitely impressed by the speed and noise settings, but color reproduction is still significantly better with the black level settings introduced by ArtZ. The color shift can best be seen when taking a low light picture with HDR+ and HDR+ enhanced, the latter will often have a green tint. ArtZ talked a bit about his settings in this post: https://forum.xda-developers.com/sho...postcount=1568 . Integrating a PH-1 specific color fix into a Gcam apk could very well be worth the work.
