Outside of the US, Samsung sells phones that use their own-branded Exynos SoC chips, instead of using Qualcomm's Snapdragon. Samsung also uses their own-brand camera sensors, whereas, in the US, they use parts from specialists Sony. Based on experience, and studies from numerous sources online, we believe Samsung's parts to be inferior to their US counterparts. Because of this Indian, European consumer gets an inferior smartphone and pay the same price as us consumer pay. 

Phones with Exynos SoC chips are shown to perform slower, have less battery life, use inferior camera sensors and processing, overheat and throttle faster, amongst other issues.
