I want to install a (or build my own) custom AOSP-based OS on my Samsung Galaxy J3 SM-J337W that has microG instead of the proprietary Google Play Services. Please forgive me if I’m doing something stupid: I’m a complete noob with this.

So, the first thing I did was check and see if my device is officially supported by ROMs like LineageOS and I couldn’t find anything. Not only that but my device isn’t supported by TWRP.

Next, I’ve done a bit of further research and read about GSI ROMs and Project Treble. The Treble Info app says that my smartphone is Project Treble compatible with the following requirements:

  • VNDK version: 28 (lite mode)
  • System as Root: disabled
  • Manifest location: Modern
  • CPU architecture: ARM32
  • Binder architecture: 64-bit However, the only a64 non-SaR GSI images that I could find are some of Andy Yan’s builds of LineageOS 16 and 17 and they do not have microG installed. Plus, I just don’t want to install any malware-infested OS from some random Joe.

I’ve been thinking of building my own custom ROM or GSI. However, compiling AOSP would take a long time.

Has anybody ever managed to install a custom OS on the Samsung Galaxy J3 SM-J337W?

    Well, they say that development for these phones is mostly dead.

    Also, I do think that getting a virus by simply downloading Android ROMs from some unknown source (or an open source project maintained only by 1 person) would be quite easy. Not to mention that xz-utils, an open-source project was recently backdoor-ed.
