In part 2 of this article of “Will the Samsung Galaxy Note 4 have a 64 bit processor?”, we discussed the likely reasons why 64-bit Apple iPhone 5S exists today with only 1GB of RAM.

Are the Hardware Manufacturers and Google Ready to go to 64-Bit?

For a smartphone to transition from 32-bit to 64-bit, every piece of hardware needs to be 64-bit ready.  This means the camera, GPS sensors, touch sensors, wifi-antenna, etc. all need to be ready for 64-bit.  Not surprisingly, Qualcomm announced three 64-bit Snapdragon chips in February 2014.  The Snapdragon 615, 610, and 410 are all 64-bit processors that are ready to take the next generation of Android smartphones to the next level.  It was not a coincidence that a smartphone, with an Intel processor, made a debut with an unfinished version of 64-bit Android OS the same month.

Considering the Note is likely Samsung’s new flagship for delivering the highest specs available across the board at the time of launch, it seems as though the stars are aligning for the first production Android to be announced as the Note 4.

The Pitfalls of Too Much RAM on a Smartphone

There’s a downside to having too much memory which is only unique to a smartphone.  Android OS still occasionally suffers from an app with a runaway process.  This means that when the home button is pressed, sometimes, although rare, the app is actively hanging on the CPU, which will drain your battery if it’s not caught in time.  An app behaving this way is attributed to bugs, and the more RAM the Android has, the more of a potential for these scenarios.  There are easy ways to deal with this problem with the Active Apps widget, but let’s hope that as 64-bit processors and more RAM becomes available on Android devices, the OS is able to better deal with runaway processes.

Can 32-Bit Apps Run on a 64-Bit Android OS?

The good news is 32-bit apps will be able to fully run on a 64-bit processor on a 64-bit Android OS, so it will be up to the app maker to migrate their 32-bit programming and optimize for maximum 64-bit performance.


Whether 3GB or more RAM is necessary on a smartphone at the moment is questionable, however it will certainly be a requirement in a few short years.  Considering we already hit the 3GB RAM plateau on the Galaxy Note 3, the Galaxy Note 4 would be a great choice to debut the first 64 bit OS and device.  My money is on the Samsung Galaxy Note 4 being announced with a 64-bit processor with 4GB RAM.  If not the Note 4 in 2014, definitely no later than the Note 5 in 2015.

  1. The key is the snapdragon 810..it will be 64bit and capable to redirection 4gb of ddr4 ram, the problem it's scheduled for production on first quarter 2015, so or Samsung delay note4 production dates or we will have to wait for the future note 5
