Samsung Galaxy S4: Were 17 parts manufactured inhouse?

Samsung published an intriguing picture on its global Exynos Twitter account about the fact that “Samsung Mobile Solutions make for the ideal smartphone system”. The picture looks like that of an etched glass block and shows nearly 20 components that goes in the manufacture of smartphones.

Given the timing of the publication (15 March) of this picture and the fact that it mentions “ideal smartphone”, one has to wonder whether the tweet is not an allusion to the Samsung Galaxy S4, which was launched the night before.
