You should have latest firmware installed on the device before downloading a custom rom witch is android 11 you can download it from here https://www.sammobile.com/samsung/galaxy-a20/firmware/ make sure you look at the back of the phone and match the model if you are with a certain carrier you should match it to. I am not responsible for what you do with you're phone

Wow! First of all i want to say it's sooo stable, sometimes i forget that it is a beta version 3 from android :eek:. And i have some bugs that i want to report. If i use something like live wallpapers the ui turn off you can only see the right arrow and the live wallpaper.
And if you turn on dark mode the symbols are broken you need to get out off the notifcationbar and scroll in it again. And gboard doesn't autocorrect me :/. And all apps you download get directly sensor permissions. And if i click on the first search result from playstore, i get a loading error and if i want to get split sreen with 2 apps the first time it doesn't work but the second time it work. And thx for the orangefox recovery and this nice rom! 😉. If you want i can add pictures too!

Well this means that the days of the a20e are numbered. There weren't as many custom ROMs for a20e from the beginning only just modified stock ROMs
a20 and a20e will be receiving custom roms probably till the end of 2022, Android 12 just doesn't work so well with it right now, eureka team is trying to make it work, at least we can have a android 12 rom with security updates I think

    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)

    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.

    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
