GALAXY S 4 Product Image (1)

Developers, get ready - Samsung has begun unleashing a barrage of Galaxy S4 kernel source on its open source repository, starting with unlocked editions of the phone and a variant bound for Virgin Mobile Canada.




The distinction between the GT-I9500 and the 9505, in case you're not aware, is one of chipset. The 9500 is the Exynos Octa-powered edition of the Galaxy S4, which has not yet had any official release date attached to it. The 9505 is the Qualcomm Snapdragon 600 variant that will be going on sale in many major markets at the end of this month. The SGH-I337M is the Virgin Mobile Canada version.

For those of us in the US, none of these things really help - all the carrier-branded versions of the S4 in America will have their own, separate kernel source releases, as all will run slightly different software builds. It's likely kernel source releases for those devices will happen in the coming weeks (or months, *cough* Verizon *cough*).

    "Exynos Octa-powered edition" You mean a dual-quad-core ;)

    • http://www.androidpolice.com/ David Ruddock

      er, I mean Exynos Octa. That's what it's called. That is the name of the product.

      • ProductFRED

        He's just messing with you, referring to the fact that it's really made up of two quad-core chips and not on octa-core chip. Marketing gimmick lol.

        • Buleaaaah

          But its has function, and yes their good in marketing.

          • ProductFRED

            Oh I'm not complaining. Just addressing the technical aspect.

        • MasterMuffin

          but the name is still Octa, not dual-quad >:|

      stay way from Exynos version if you want (you do) to run any AOSP based 3rd party ROM (CM, AOKP, PA...) as it is a black box and a hell to hack (see S3/S2 forums).

      Go with S600 which is greatly documented by Qualcomm (arguably the best developer friendly SoC company right now) and have a stellar support for many years....

      Any AOSP Rom will fly (at least) twice as fast on qualcomm quad core than on any highly-overclocked-twenty-core Exynos - which will be plagued by TouchWiz and Samsung's kamikadze software devs in the end...(and some modal windows here and there ;-)

        This is so true, wish I had known before I picked up the International S3 but won't be making that mistake again.

        Good luck with Air viewing, multiwindowing on AOSP roms

      • Sean Royce

        Isn't that why the Exynos kernel was released? Or does something else have to be released in order for custom roms to be stable.

      • KaliK0t

        And miss out on the main selling points of the S4 such as multi-window, Smart Stay and Camera software.

        Okay bud, to each his own

      • hellodds

        A grade IDIOT. Learn how to read little buddy and you'll realize the point of this article. Down with the f%^&ing inferior Snapdragon600 forever. Samsung should use their brain before pulling a stunt like this again.

      • pio66

        That is an uneducated guess and boosting self phone ego lol first off only cm said it was not getting the i9500 there are other ways to get aosp than cm code i mean come on aosp blowing away with speed your sadly again wrong running aosp with the same soc in my htc one scores half my score running with stock or cooked rom . So again that makes no sense at all . Touch wiz is a user interface that can be removed and replaced with another launcher . Now i have both sprint and i9500 versions of the s4 running a custom bare bones rom on my i9500 that has an 31,120 score on antutu and neither my on or us s4 can get even over clocked within 2000 points so idk why giving bs info will help anyone here . Also sorry to let you know the cpu issue in the i9500 will most likely be fixed upon 3rd release of kernel source at least is what gakan moral says or siyah kernel creater also andrielux has the i9500 and is honestly one of the most talented kernel devs ive seen or you hqve as well lol

    • Dulshan Kalpage

      Try merging 2 CPUs of different architectures to work alongside each other. The "Octa" holds true considering there are still 8 cores and as you know all 8 dont run at the same time just like all 4 cores rarely run at once on a Quad core chipset.

      My i9500 underclocked even to 600Mhz with bloat removed can last around 15 hours of power use. And even with such a low clock speed and TouchWiz removed, the thing flies.

      Once the new 3.9 - 3.10 kernels will be implemented with full HMP support you'll see this chipset perform even better as well as provide even more battery life.

    The SGH-I337 (not M) is bound for AT&T, I believe.

    • Andrew Kachaniwsky

      Also for Rogers, Bell, Telus and all Canadian carriers.. not sure why Virgin is singled out.

      • http://www.androidpolice.com/ David Ruddock

        Do you have a source on this? I really couldn't find any specific reference other than Virgin.

        • http://www.androidpolice.com/ Artem Russakovskii

          I think that's pretty much the case with every phone, they slap an M at the end and it's meant for Canadian carriers. See previous Galaxies, for example.

        • Andrew Kachaniwsky

          Not one that I can share, sorry.

        • silver_arrow

          All Galaxy devices sold in Canada have an M on them
          S3 Canada - i747m US -i747
          Nexus Canada- i9250m US i9250

          It's somethign that they always do so there is a good chance AT&T is getting the i337

  • http://twitter.com/ScottRFrost Scott R. Frost

    Any word on if the Verizon version will ship with a locked bootloader?

    • silver_arrow

      It's Verizon... they will probably say Samsung made them

  • I Like Games

    I assume they won't release anything for the processor which was the problem with the S3 i9300 and why the CM team dropped any new Samsung phones.

  • Théo Coutu

    Is the VMC version identical to the i9505?

  • http://twitter.com/BideandFecht Nathaniel Lee

    Do you have a tech spec chart for the SGH-I337M? Even just proc/soc would be more than what I can find right now...
