Recently, South-Korean mobile manufacturer Samsung unveiled the Galaxy S2 Plus officially. Samsung brought the device with 1.2 GHz Processor. Today, a new report has claimed that instead of packing Samsung’s own Exynos 4 chip on their newly arrived device, Galaxy S2 Plus, it packs a Broadcom chip.
Back in December last year, a major security issue was found by the XDA-Developers’ forum member, alephzain which will affect most of the Samsung devices using Exynos 4 SoC and Samsung Kernel sources. So, it is likely to be the most probable reason for using Broadcom chip instead of packing their own Exynos 4 chip on the Galaxy S II Plus. But later, Samsung announced that they will fix the Exynos vulnerability issue via a software update as soon as possible.
The Samsung Galaxy S II Plus includes a BCM28155 SoC inside. This chip consists of dual-core 1.2 GHz ARM Cortex A9, and a two-core Broadcom VideoCore IV GPU. This Broadcom SOC also has an integrated 21 Mbps HSPA+ radio, dual band Wi-Fi, NFC. The chip is made using 40 nanometer transistors, so it draws less power. This Broadcom chip is used on other Samsung devices, Galaxy Grand and Grand Duos also.
