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.

The list of components is as follows (out of which a possible 17 were possibly used in the S4). Only a proper teardown will allow us to find out how much of the S3 is Samsung-sourced.

MicroSD card: An optional component. Amazon sells a 64GB part from Samsung for only £37 (opens in new tab).

Flash LED, Camera Module, CMOS Image Sensor: The Samsung Galaxy S4 uses a 13-megapixel model at the back.

Linear Motor: The part that makes the phone vibrate.

A slew of minuscule addons: Sideview LED, adapters for connectors, power management IC, NFC and embedded Secure Element, WiFi module, Multi-Layer Ceramic Capacitor and Heading Data Interface (HDI).

Mobile Display Driver Integrated Circuit, LCD or OLED: The Galaxy S4 uses a 5in 1,920 x 1,080 pixel panel built inhouse.

Application Processor: The international version of the S4 houses an Exynos 5410, the world’s first 8-core SoC.

DDR3/eMMC/LPDDR2/eMCP: The S3 is one of the first smartphones on the market to use LPDDR3 which will provide with much more bandwidth for data hungry applications.
