ANXCamera v204 Pre-Alpha Instructions
hi• Uninstall all previous versions of ANXCamera (Even if it was included in your ROM, it should be nuked before flashing), reboot, flash via Magisk.
• It is a Magisk Module, which means you flash in Magisk Only. Recovery installations are not supported.
• For this version you do not need MIUICore to flash ANXCamera, you can remove it if you like. If you still want to use MIUI Gallery, you will need MIUI core. The recommended version of MIUI Core is v2-D and for MIUI gallery, anything below v2 global or v1.0 stable for the Chinese gallery. If you want to use a newer MIUI core, use the -D version only.

Fixing Bugs Manually
You can fix whatever little issues you have such as dual video, Portrait mode, HDR, etc. by following this guide here.
Some people have asked, why don't I make one new zip with all the fixes included? This is because these fixes are sweet specific and don't work on other devices. Downloading from pling helps support development for potential future versions, that's why I recommend you download the zip from pling and do the fixes manually.
• No bug reports! This is a Pre-Alpha version that has the risk of coming with an unknown number of bugs but after applying the fixes I have not noticed anything major.
• This version has been tested on ArrowOS (with the fixes zip) and ShapeshiftOS. If your maintainer uses different device sources it might not work, try at your own risk.
