Samsung Galaxy S4 easy to repair says iFixit, after a teardown leaves the flagship naked
Behind the screen is the Synaptics S5000B touchscreen controller which is so sensitive that a user wearing gloves can still control the screen. The parts in the phone are exactly as expected for the U.S version of the device which means that the octa-core Samsung Exynos 5 processor is replaced by the quad-core 1.9GHz Qualcomm Snapdragon APQ8064T processor, which was hidden underneath a large Samsung chip on the motherboard. Interestingly, the Qualcomm WTR1605L Seven-Band 4G LTE chip is inside the device. This is the same chip found inside the Google Nexus 4 that gave owners of the device the hope that there was hidden LTE support on the unit. The Qualcomm MDM9215M 4G GSM/UMTS/LTE is the modem used on the phone.
Last week, Samsung said it would stop using tin solder sourced from dangerous mines in Indonesia, but the new supply of the solder has probably not had enough time to make it through to models already produced and boxed.
