------------ Short Background --------------------
There are many custom roms for A20 while no roms for A20e. But two phones are very alike. Both uses Universal7885 SoC as base, have same GPU (Mali-G71) etc etc... And because we have a vendor partition, all the device specific files are in there. So this ROM works like a GSI, but for Samsung phones, for Universal7885 phones, for A20, A20e. Only difference is kernel and dtbo. All ROMs are ported by Gabriel260.

------------------- Working and Not Working----------------------
Same with A20.
WORKS:

  • RIL (Calls, SMS, Data)
  • Bluetooth
  • Wi-Fi
  • Camera
  • Video Recording
  • Video Playback
  • Audio (Record and Playback)
  • Sensors
  • Flashlight
DOESN'T WORK:
  • VoLTE and bluetooth calls (Blame Samsung for that)
  • Feel free to report any issues you may encounter with relevant logs

--------------- Options ----------------------
  1. LineageOS (https://github.com/LineageOS)
  2. dotOS (https://github.com/dotos)
  3. FluidOS (https://github.com/Project-Fluid)
  4. ProjectSakura (https://github.com/ProjectSakura)
  5. HavocOS (https://github.com/havoc-os)
  6. crDroidAndroid (https://github.com/crdroidandroid)
------------------- NOTE ------------------
This installs Eureka Kernel and Magisk (For some Roms) and patched dtbo
Eureka Kernel Reference : https://forum.xda-developers.com/t/...-of-galaxy-a20-based-on-android-q-10.4159529/

Some people have a20e twrp which has a10 prop value. Which prevents installing. Install TWRP from the one in downloads.
If the phone is stuck in black screen after install, just soft reset the phone

Added PixelExperience which i built myself. Note: It has S10e Korean Varient FingerPrint. You can always change this with MagiskHide Props Config

(2021 05 05 KST 10:30)
PixelExperience: Update to May 5 Security Patch
Note: PixelExperience has a bug which prevents booting. In order to fix temporaily, copy this xml to /system_root/system/etc/vintf/manifest.xml in TWRP
I will soon do a rebuild with a fix

I was really excited by this, but unfortunately, in my case, after flashing the lineage file with my TWRP (version 3.5.1-9-0) and restarting, it refused to load (just a black screen...). I tried with both enforce and permissive.

Samsung A20e, SMA202F.

I had to return to the custom ROM I was previously using, the GSI image created by AndyYan (https://forum.xda-developers.com/t/gsi-11-lineageos-18-x-gsi-all-archs.4205461/


For some reason, I couldn't load that GSI custom rom as well after flashing, so I reflashed the stock ROM with Odin, then installed TWRP and then the custom rom.

For those interested, with my phone both lineage-18.1-20210411-UNOFFICIAL-treble_arm64_bvS.img.xz and lineage-18.1-20210411-UNOFFICIAL-treble_a64_bvS-vndklite.img.xz worked.

Good luck with your work!

Seriously, I don't get what you mean. The lineage OS boot perfectly with my phone.
Have you tried forcing the phone to reboot? That bug can happen. If you rebooted the phone and blank screen was greeting you. It is most likely to be solved by soft reset

It may be I did something wrong or that I didn't try hard enough, I'm not an expert on flashing, I only flashed my phone like 3-4 times and my Tab3 10 like 2-3 times.

I tried several times restarting, it didn't work. Maybe a step-by-step guide would be useful.

I apologize for not previously being constructive. Your work and that of other developers here on XDA is very important.

How would I change the charge animation on this ROM, like the animation that plays when you plug in the charger
 
If a new update for Android 11 comes out how am I meant to update the stock rom

My understanding is that you flash with Odin the stock firmware (BL, AP, CP, CSC), then you flash the TWRP (AP) with Odin, wipe everything, then install the custom ROM.

Before doing this, make a backup of your files.

You can also backup the entire system with TWRP in case something goes wrong with the new firmware. To return to the initial system, after a complete wipe, you flash in TWRP the resulting zip files.

You can also use a backuo app. At the moment, from my own research, the most user friendly app seems to be Migrate, available on Google Store/Aurora Store by BaltiApps. There are tutorials on YouTube on how to do this. My understanding is that in some exceptional cases, you need some maanual tinkering to complete the backup -see tutorials.

Please note that Migrate needs root. There are also other backup apps that do not need root, with different level of efficiency.

I haven't yet used Migrate, will try it after the Android 11 firmware update.

So the idea with Migrate is that you backup your files, apps and phone settings in some zips and after reinstalling the custom rom, at the end you also flash with TWRP the Migrate zips.

The above is solely based on my few months own research and experience, so you should do your own research.

I'd like to double the question from Naksuhd. I'm thinking about buying this phone and would like to know if there are any stable alternative ROMs for everyday use before deciding.

Hi, I wasn't able to find a ROM for myself for this phone.


Personally I use AndyYan's Unoficial LineageOS GSI 18 (https://forum.xda-developers.com/t/gsi-11-lineageos-18-x-gsi-all-archs.4205461/), but with no Gapps, as I was looking for a de-Googled phone.

Apart from a few bugs, the GSI is updated monthly and is usable on a daily basis.
