The launch of the Samsung Galaxy S21 series is about a month away, but the information about the upcoming flagships is reaching its full force. The new developments shed light on the regional differences between the variants in India and other countries. While official confirmation is pending, the Samsung Opera House store is already providing details on impending smartphones. The launch date of the Galaxy S21 in India will be January 14, along with the global unveiling. Blind pre-orders are already open against an advance of Rs 2000, but it looks like sales won't start until January 29. In India, the available color options will be grey, pink, purple, white and black, but not all colors will be available for all models. This is a big problem because Exynos variants have generally had relatively worse performance and battery life than their Snapdragon counterparts. According to additional information received by the Android Authority, the Indian variants of the S21 will be powered by the Exynos 2100 chipset. It appears that the Snapdragon 888 variants will once again be restricted to the United States. Samsung hasn't announced the chipset yet, but we've recently seen it on Geekbench. If these specs are to be believed, it will be an octa-core SoC with four Cortex A55 cores for efficiency, three Cortex A78 cores, and a yet-to-be-confirmed performance core, probably the new Cortex X1. Some rumors also mentioned the inclusion of a custom AMD-designed GPU, but there isn't much substance to back that claim yet. The price should be similar to the S20 series. At launch, there will be three variants of the device viz. Samsung Galaxy S21, S21 Plus and S21 Ultra, the main difference is screen size, battery capacity and cameras. We also expect to see the launch of the Samsung ISOCELL HM3, which is said to be a significantly better 108MP image sensor for high-end smartphones. The scene will be shared by the Galaxy Buds Pro, Samsung's next premium TWS with noise cancellation.
