Samsung launched its latest flagship Galaxy Note 4 phone at IFA 2014 a few weeks ago, and the handset has been said to be running on an Exynos 5433 chip (although Samsung has been quite restrained with the details).
However, a piece of leaked source code reveals that the processor is actually an ARMv8/64-bit chip. All that is nice and nifty, but it appears that, inside the phone, the chip will run only in 32-bit mode. Or at least only for the time being.
