Back in August of '12, Sony teamed up with Google to make the Xperia S an officially supported AOSP device. The project initially got off to a decent start, but after an issue with some proprietary software binaries that couldn't be released by either Sony or Google, the project was canned on the official side and moved to Sony's GitHub, where it can still be found today.

Now, the company is doing something similar with the Xperia Z, minus Google's interaction from the get-go. It has released full AOSP for the Z to its GitHub, along with most of the proprietary binaries needed to get things going. Unfortunately, both the modem and camera require binaries that can't be publicly released.

Still, the project is already off to a promising start – it boots, and the SD card slot, Wi-Fi, Bluetooth, GPS, LED, and most sensors are working. With that said, it's not meant to be a daily driver at this point, but more of a fun tweaking project for those in the development community who are interested in getting a pure Android experience on this device.

The code and all available binaries can be found on Sony's GitHub, and developers are encouraged to make themselves familiar with the code, take a look at the list of issues, and start tweaking. More information can be found at Sony's developer blog below.

      I'm definitely considering a Sony next time. If they made a Note 2 or 3 challenger, I'd definitely buy it. Sony phones are always sexy.

          6 and a half inches is WAY too big. It's only half an inch away from a Nexus 7! All I want is a phone the size of the Note 2 with better build quality and better software.

            not what SHE said

        • Ambroos

          6mm, glass on both sides and 3500mAh? Yeah right, typical speculation. The Xperia Z was going to have an Exynos according to Esato too.

          • http://www.facebook.com/yasser.syed Yasser Syed

            Nope it was always the qualcomm S4 pro not exynos.
            Sony phablet will have similar looks like Xperia Z.
            Its something like this looks wise
            Xperia Z,Xperia Tablet Z and later Xperia Phablet they will borrow each others design and slimness.

        Just don't expect to see any updates in a while. That is, official Sony ones. That's the only real complaint I have of Sony phones (owning an Xperia S).

  • Sonny

    That's the spirit! But modem and camera wouldn't hurt either ;-)

    In the demo, clearly 3G is working, the camera is working. So... Sony makes that video, but decides to not upload the relevant codes for those components... Wait what?

    Very excited to see Sony continue the AOSP effort on their flagships (albeit only the second one) nonetheless.

    • Ambroos

      Sony has the required binaries to make them work, but they can't release them. Cyanogenmod devs can just use ones extracted from the regular ROM's, but it's a bit more complicated. Legal issues, basically.

      • http://twitter.com/joonsunn Joon Sunn

        Can't they 'leak' it?

        • Ambroos

          No real need, modem already works fine in Cyanogenmod, camera is pretty good too (I think). Sony still is a company that likes to do most things behind closed doors, there's a lot of internal approval needed for some things. It's still pretty amazing what they're doing, this is an incredibly good starting point for ROM devs.

          • http://twitter.com/joonsunn Joon Sunn

            Thanks for that insight. Now the remaining thing is how much will this translate to the ZL, which has essentially the same hardware (with the addition of a camera button).

          • Ambroos

            Probably all of it, an official Cyanogenmod (from the FXP team) is already available for all Qualcomm-based Xperia devices, they're pretty brilliant. Porting this to the ZL probably only takes a few minutes for an experienced developer.

  • letsjustgetalong

    Just hung up on dianne ?!?!? WTF how rude never going to buy a Sony device again! Just kidding but I would've picked up the xperia z over the s4 if it had a bigger battery and a snapdragon 600

  • ssj4Gogeta

    Wow, they're really serious about this. Well done, Sony. I'm sure it'll also benefit them in the long run, as they'll now have many developers who will contribute code that they can merge back into their skinned codebase as well.

  • József Király

    Hopefully this sets a standard in the future of Android, for both the small chinese manufacturers and the bigshots. I can easily imagine that only because they would loose a significant fanbase (who buy their phones for hacking the stahko out of em), many of the bigger manufacturers (LG, Samsung, Motorola (??) and HTC) would be soon releasing full device trees with their appropriate changes. Taking it even further, I think even some proprietary binaries will be open-sourced, or at least the licensing will change to support free distribution.

  • Jack

    I just bought an xperia Z and now I am super happy about it. Thank you Sony for not treating developers like a bunch of cheap hackers.

  • Garry DeWitt

    Just bought an HTC one, and it seems like Sony is intent on making me regret it. good job guys, keep it up.
