Resources.UnloadUnusedAssets not working as expected on mobile

Unity Engine

In my app I am using Resources.UnloadUnusedAssets(); and it is triggered as part of the device low memory warning. I have a OnLowMemory() method that I manual trigger on desktop to test this feature and it works as expected by removing & unloading all “old” texture resources.

On Android however it seems to remove ALL textures whether referenced by a material or not.

Is this a known issue or is there a known workaround at all?

from this link I learned that UnloadUnusedAssets will remove currently visible textures if they have a weak reference. I additionally assigned my texture to a strong member variable and viola.
