They manage to unlock big.LITTLE to 8 real cores
The Exynos SoC consists Octa May 4 core Cortex-A15, which are used in processing intensive applications, but also has four cortex-a7 cores which are used only for light work. Getting a good balance between power and energy saving.
The SoC is able to use his 8 cores simultaneously, as these are automatically exchanged on demand applications, ie in high demand, the 4 Cortex-A7 are disabled, leaving control to the 4 core Cortex-A15; light tasks while the opposite occurs: the Cortex-A7 SoC are activated while the Cortex-A15 are disabled.
A user of Android Central community, reports having “deceived” big.LITTLE into thinking that is in sleep mode, activating both the 4 cores such as Cortex-A15 Cortex-A7 4 cores simultaneously in a Galaxy S4, turning to 5 Octa Exynos SoC eightfold an authentic core.
You went beyond the 8-core overclocking to 2.8GHz, and performing tasks for almost an hour until SoC fell in battle, suffered overheating victim operate beyond its specifications.
Obviously not recommended to anyone using smartphones and / or tablets based on arm SoCs big.LITTLE forcibly activate the 8 cores in their SoCs.
