Got 5.0.1 on my N4 910L- why is it not 64 bit when my Exynos version is a 64 bit enabled chip?

Says its 32 bit 5.0.1 and my Exy7 is 64 bit octocore? Any ideas what the deal is. Korean model sm-g910L

Good question but I believe the only device that 64 bit Android was released/built for is the Nexus 9 tablet at this time. I'm sure that is going to change rather quickly going forward.

Just read on android authority that sammy is likely to only release the offical version of its software in 32 bit treating snapdragon and exynos notes fairly.

64 bit will come out when it is necessary to do so. It's going to be a transition - all of the software will work, of course, but a lot of hardware on different phone models are going to need 64-bit drivers and that's not a trivial undertaking.

At the moment, 32 bits can natively address 3.5GB of RAM. Software can be interpreted (Dalvik) or compiled (ART) using 32- or 64-bit compilers with little to no difference in performance. The rest of the hardware will not see any measurable difference based on whether the software is running 32 or 64 bits.

The very first phone that comes out with 4GB of RAM will likely also come out with the first 64-bit implementation, unless someone else wants to be first for bragging rights.
