A couple of months ago, a number of team Hacksung/CyanogenMod members expressed frustration and doubt regarding the fate of the popular custom ROM when it came to Samsung's newest flagship - the Galaxy S4 (see our review). Other CM members quickly put an end to the misinterpretation, but not before some prematurely jumped to incorrect conclusions. Needless to say, when Steve Kondik, a.k.a. Cyanogen, took to G+ to announce the first upcoming S4 builds, he couldn't resist the opportunity for a healthy dose of sarcasm:


His follow-up messages confirmed that the T-Mobile and Canadian S4s were first in line, followed by the international i9505 at some point in the future when the team gets a hold of the hardware, though it's not clear whether the i9500 or other Exynos Octa variants will be supported. Samsung already released kernel sources for all of these devices earlier in April.


We didn't have to wait long as the first CM 10.1 builds for the T-Mobile (SGH-M919) and Canadian (SGH-i337M) S4s are now available for flashing from CyanogenMod's download site:

Note: The "EXPERIMENTAL" part of the file name is normal for on-demand builds that were triggered outside of the normal nightly schedule. This happens for initial snapshot builds a lot when they're first released so that we don't have to wait half a day for the next scheduled build time.

According to Steve, "there are a few rough edges still, but will be ironed out in short order and you should be able to use it as your daily driver without serious issues."

Definition: A "nightly" is a bleeding edge release that is built on a daily basis, usually at night after a full day's worth of new code has been committed.

It could oftentimes be unstable and not properly tested, lacking any changelogs, but eventually evolving into alphas, betas, release candidates, and finally stable releases.

If you're a developer interested in building or contributing to CyanogenMod for these devices, the relevant source trees are located at:

2 1

Note: The screenshots were taken before the builds became official, which explains the UNOFFICIAL part of the version

Of course, the Verizon version isn't even out yet, and the AT&T one is locked up, with kernel sources MIA. As I sit here shaking my head at AT&T, we're stuck in limbo waiting for the unofficial unlock to be released by Dan Rosenberg. Until then, you probably shouldn't count on any action from CyanogenMod or any other ROM developers.

    Steve Kondik has done so much for android....

  • http://riteshtripathy.wordpress.com/ Ritesh

    And the HTC One? Why's there no official CM 10.1 build out yet for it? I know they are working on it and already have a functional build going but how did the S4 get it so fast?

    • Offender

      Why would you want to break a new HTC One with CM?

      • http://riteshtripathy.wordpress.com/ Ritesh

        Erm.. just to test it out. I love stock Android, you know.. Though I know it'll break the camera to garbage and I'll probably return to a Sense 5 ROM rather quickly, just for the camera.

      • Always Online SUCKS!

        Why not? CM is a whole lot better than Sense in the first place and it isn't as bloat heavy.

  • http://www.facebook.com/georgealexiouvalentey George Av

    They said they won't support the S4.. Their supporting the S4...

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

      Did you even read the post?

      • http://www.facebook.com/georgealexiouvalentey George Av

        I wouldn't comment if i didn't read it..

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

          Then I am not sure what you are asking. The CM team made it clear that no decision about S4 support was made at that time.

          • http://www.facebook.com/profile.php?id=1745689461 Hal Motley

            Knowing what happened with whole Exynos scandal, it's still going to be sketchy with that chipset. Good thing that if I go for the Samsung Galaxy S4 it will be the Snapdragon version, even if I need to import it...

          • http://twitter.com/xplodwild Guillaume

            Might be worth mentioning again hacksung was talking about the Exynos variant also :)

        • Kcls

          Then you might want to go back and read it again. Don't skim.

    • squiddy20

      1. *They're

      2. From this article alone: "a number of team Hacksung/CyanogenMod members expressed frustration and doubt". Now, does that say "team Hacksung/CyanogenMod members won't support the S4"?

      • RoboBonobo

        He obviously meant that 'supporting the S4' belongs to them.

  • disqus_gvHzXAf4OJ

    Is the cm10.1 also able to use all the new sensors?

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

      According to Steve, the S4's screen hover functionality should be supported, so developers should be able to utilize it. I'm not sure about all the other sensors, but most should be supported.

  • fredphoesh

    Why spoil a sgs4 with CyanogenMod? Half the point of getting a sgs4 is the samsung wizardry in the software... for example the awesome camera software!

    • http://twitter.com/ToysSamurai Toys Samurai

      Not everyone like all those S-ware. On the other hand, I do agree with you that there's little point of getting a S4 just to replace the whole thing with CM and lost most if not all S-ware. Once a S4 is running CM, it's nothing more than a big Android phones with slightly better hardware than most other phones currently in the market. Arguably, a Nexus 4 is a much better and cheaper choice is all you want is CM (even though its hardware is beginning to see its age when comparing to the S4.)

    • squiddy20

      Maybe you just really like Samsung (as a company) and plastic, and want stock Android?

    • Offender

      There's one thing about CM you can always count on, somethings always broken. I never understood taking a working rom and replacing it with rom that isn't 100% functional? If you don't like some of the s-ware than remove or freeze it with Titanium BU but I can guarantee that when you take your s4 out of the box, it all works!

      • Kevin Aaronson

        A great observation! CM was the first rom I flashed for my gs3, and bluetooth and other gs3 specific features were(and are) broken.

      • Bakaouji

        How about you try CM on a phone that ISN'T exynos or tegra? You'll be surprised to learn it's damn stable. I've been using CM10/CM10.1 for over a year on my phone and tablet, no bugs or issues.

        • Björn Lundén

          Nice to see someone who understands the difference the SoC used makes. This point can't be stressed enough.

          It's also why referring to the Samsung devices by their S-name is so misleading. An Exynos Galaxy S3/4 has very little in common with a Qcom Galaxy S3/4 apart from the outer chassis and display.

          • Bakaouji

            Agreed. CM10.1 on the i9505 was pretty much guaranteed. It's the Exynos i9500 version that will have stability issues and wary devs.

    • Always Online SUCKS!

      Not everyone enjoys bloatware on their phone. Also touchwiz is ugly as hell which is the only thing that makes most people hate the stock ROM.

      Holo is nice and clean, whoever made touchwiz thought the complete opposite and made the most ugly looking UI which extra large text and bunches of random colours.

    • Bakaouji

      Perhaps if you want an android device with top hardware (including a microsd) that's running a non-bloated form of android?

      • On a Clear Day

        But if you can turn off most of the bloatware so it doesn't start as I think you can, what is the point really? And I am asking seriously, not sarcastically, so please don't respond sarcastically.

        • Bakaouji

          A few more reasons:
          - The S-Crap could be turned off, but touchwiz as a whole is still really bloated, cartoonish and cringeworthy. Many people have even reported lag on the S4, which can be solved through a (stable) AOSP based rom.
          - Many people prefer the simplicity of Holo.
          - You'll often be able to get onto the latest android earlier through CM

          • On a Clear Day

            Thank you. Would that mean the photo features as well as not having to touch the screen though would be inoperative?

          • Bakaouji

            Yep. In essense you would have the software of a Nexus 4. There are clear disadvantages in going to AOSP from touchwiz or sense (e.g. camera will also not be as good), so it's not for everyone. It's always worth a try though!

    • omegavesko

      What you call wizardry, most people call bloat. Several gigabytes of it, even. I don't appreciate TouchWiz still looking like the UI designer was a 5-year-old, either.

      Personally, I won't even remotely consider buying a device without knowing there's a stable AOSP-based ROM available for it.

    • On a Clear Day

      Though I do like the idea of having complete freedom to do what I wish with a device I buy and in the process eliminate bloatware, it seems to me that the use of something like CyanogenMod for someone who wasn't truly aware of all the potential problems - like security issues or bricking a phone - could prove to be a total disaster.

      As I understand it, from Ice Cream Sandwich forward it is possible to turn off most pre-installed apps you don't want running permanently so they don't self-start. Perhaps I am wrong, but still, I for one, feel that the advantages of Samsung's software outweigh the negatives. Especially given the phone has more than sufficient processor speed, RAM and internal storage - as well as SD card.

      I can't really see the advantages of rooting it, but perhaps someone will take the time to list what they might be.

    • kosiara

      I would NOT buy a phone without CYANOGENMOD support! This is the fastest, lag-free and stable Android version you can get. If I have to choose between functions and stable, smooth and beautiful AOSP version of Android - I choose cyanogenmod! If samsung does not release source codes for their Exynos with the camera bug fixed, they're finished for me.

  • Ella Puerto

    Am I the only one who noticed "20130504" in the version? Its read as 2013 05 04.

    • Magnus

      What's odd about that? It's the most logic way to represent a date.

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

      Did you also see the "tmo" in the build name of the T-Mobile version? Mind-blowing coincidence!

    • Floflo

      So? That's yesterday's date...
