Models affected by light probes look very odd on mobile (iOS), but fine in the editor

Hi,
I'm experiencing a weird issue where light probe-lit models appear dark in odd places on my iPhone (And other iOS devices), but perfectly fine in the Editor.

Here's a screenshot of how it looks in the Editor (Looks fine here):


Screenshots from my iPhone (As you can see, the arms are oddly dark in some areas, which makes them look very ugly):





It would be great if I could get some help with this.

Thanks,
Lucas

 

Please help me with this, this makes the game look very ugly on mobile!

 

Can anyone help me?

 

What have you tried to fix the lighting issue so far?

Different kind of light?
Delete light probe - recreate light probes?
Different rendering method?
Different color space?
Does it happen on a placeholder mesh in the same spot?
Different texture?

 

Nevermind, figured out it was a weird error in the shader that only happened to affect that mesh.
