What was the logic of raising GST on mobile phones from 12% to 18%?

Hello everyone,,

There may be parts on which 18% is levied but what is the fundamental problem if the final product attracts 12% GST instead of 18% GST? Was this increase done just for convenience? Why does every part in the supply chain need to have the same rate of GST?
