List of Bugs I Found in Version 12L Shinju(11.07.2022) on the Samsung A20 (205F) Device

- The Notification Panel Doesn't Appear Completely, And Notifications From Applications Don't Appear ( There are also other issues that appear such as the back button showing up even though I'm using gesture mode, the Developer options won't open, etc. )
- The Sound Produced When Using a Bluetooth Speaker is Too Small Even though the Volume is Full
- The device feels warmer faster even though the condition is idle
- The device sometimes suddenly hangs and can't be used (Solution, restart the device)
- In my opinion, the sound quality that is issued by the Dolby Atmos feature feels different when used, not like Dolby Atmos on Samsung's stock ROM

maybe that's the only problem i found when using this Rom. I hope this problem can be fixed in the next update.

    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
