What is causing this lighting issues? And how can i fix this?

I am using asset bundles. On pc everything looks fine but on mobile lighting is pixelated (or textures idk). I’ve been googling a lot and playing around with settings and also changing compression methods but nothing helped :c

This is due to texture compression. Not all compression algorithms have this issue.

You can see the different compression formats here:
