I just checked and noticed that the kernel of the galaxy note 4 exynos version has the instruction set arml7 which is a 32bits. which is weird because it’s 32 bits for an octacore cpu.
I’m not sure if the android system is in 32bits or if it’s the hardware. Anyway, now I’d like to know if I can do anything to upgrade my android system to 64bits, or just package to 32bits ( armv7 ) and have a good performance in VR
