I found the file where boot animation is stored on the pixel 4a. It's not under system/media it's in product/media. None of the boot animation apps work. And the magisk module for changing animation doesn't seem to work on my device. When I try to physically put a new bootanimation.zip in /product/media it won't let me says my root directory is 100% full. I always like using a custom animation. Does anyone have any ideas how to get this done?
