This is a small project based on AOSP. We try to be a platform for beginners and support the Custom ROM community with our own unique contributions as well. This ROM exists thanks to inspiration of AOSiP, Thank you! #StayDerped

Code:
/* Your warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/

GApps included!

What's broken?

- VoLTE (This depends on Samsung Frameworks)
- Netflix HD (DRM Widevine)
- On some a20e devices, NFC is dead. (Will be fixed on next release)

    I know man I am now using dot os 5.2 but I want to test new features which I have never experienced in android 12.1
    Derp is dead, dev deleted the source. The eureka team said that only some roms would be coming out on this month. Ancient is dead for a20 probably so the only official 12.1 rom we have for a20 is Spark OS

    Sadly they don't seem to be built after the initial build. Maybe it's a base for someone to pick up

    If this is dead what is the best ROM to use with our little a20e?

    I've just bought this phone so it would be interesting to know.

    Thanks.
    Currently nothing. We have to wait a bit to see if someone starts building a different ROM for it. In the meantime you can still use it since it's very functional and doesn't lag as much as previous versions with the older kernel.

    March SPL is delayed because there is no Android 12 with March SPL, but there is Android 12L now. Derp main dev is WIP merging now, will build after he finishes merge as soon as possible.
