This Module enables RAW Capture on the Galaxy A20 and Galaxy A20e, and changes the camera Hardware Level from Limited to Full.
RAW Capture is required for most GCams to work.
For information about GCam, go to this thread.

How does it work?
It works by replacing the library located at /vendor/lib/libexynoscamera3.so with an edited one. For reverse engineering enthusiasts, here is the patch applied to the library.
Prerequisites
- Magisk v20.4 or newer
- Android 11 vendor and kernel (Not compatible with versions of the Eureka Kernel older than 9.0)
Installation
Install as a normal Magisk Module, through Magisk Manager or TWRP.
Troubleshooting
Camera doesn't work, shows Black Screen
Make sure you are using a compatible Android 11 kernel and vendor.
If this issue is happening after updating your firmware, please let me know.

great job, you should do one for the custom roms, i'm stuck on the samsung one cause this mod only works there, when i install in other roms the camera stops working

In which ROMs have you tried it? It should work on any as long as they use an Android 11 vendor and kernel.

Did those ROMs ask you to flash a custom kernel/vendor? If that's the case i'd suggest to try in phhusson's AOSP GSI with stock Android R kernel and vendor.
I can't test it on my phone right now as i don't have enough free space to make a TWRP backup.

The kernel used by that ROM is using the camera drivers from Android Q, that's why it's not compatible with this module. You will have to use another kernel or build its kernel without this commit.
Edit: This module may work with the OneUI 3 variant of the Eureka Kernel, but you will most likely run into some issues. Feel free to try it and tell me if it worked or not.
Screenshots
Thread updated. Added module for the Galaxy A20e.
Version 2.1 of the module released, the biggest change is that there is no longer a need to change the Black Level in GCam settings, so GCams (or other camera apps) that don't have this option should now take photos without pink tint.
Full changes can be found here.

Hi, i am a member of the Eureka Team. As you may know, we make AOSP ROMs too, but we were using Q camera blobs on our vendor, till now, and we are going to switch to R camera blobs.
I'm wondering if we can use this module's library for our team's roms, we will credit you correctly. On our posts and etc.

If you use Android 10 with an 11 vendor it should work fine. I don't know if it's possible though, maybe with PHH's GSI.

Thanks man, it worked successfully
Hello, everyone!
I just got a J4+ from a family member after my iPhone stopped working, I've been an iOS user for over 4 years.
Before moving to iOS in 2017, I used to be a Samsung/Android user and I also used to install custom roms on my phones but I see that things are a bit diff now.
What is the best custom rom for J4+? I need less lag on apps like Instagram (specially in the camera section), TikTok (videos lag a lot on One UI) and on games.
I see that nowadays you need to unlock the bootloader in settings and then flash some unlocking stuff on TWRP before being able to install roms? I'd need quite a guide, if anyone can help
Thank you!!
phhusson's GSIs.
This link always points to the latest release.
This link points to v313, (maybe) the last version that will work on J4+ since it is an A-only device.
Remember to use the arm-aonly image. Either Googapps or Vanilla variant is fine, it's up to you.
See here for instructions:
How to flash a Generic System Image (GSI) on Project Treble supported devices
So your device supports Project Treble, what does that mean for you? It means you can flash a Generic System Image such as LineageOS or Resurrection Remix! Enjoy AOSP-based custom ROMs! Here's a guide on how to install these ROMs.

TWRP 12.1 for Galaxy A53 5GInfoNOTE THAT THIS IS A WORK IN PROGRESS. IT IS NEITHER BUILDING NOR RUNNING AT THE MOMENT.
Also note that I never ported a TWRP device tree for any other device before.
I started working on a TWRP build for the Galaxy A53 5G. More specifically, I started extracting the device tree with the twrpgen tool using the original stock recovery.img.
Then, I adapted the output to match the new "twrp" style syntax, as the twrpgen tool still produces the old "omni" files.
My hope was to get at least the build process running inside GitHub actions, such that we have a CI pipeline running for this where everybody can easily contribute and improve.
While the build actions sometimes seem to succeed, the out/target/product/a53x/ folder contains neither a .img, nor a .zip file, which I could upload to the phone.
Even though this is not building at the moment, it might be some time saver for somebody who has worked with TWRP builds before and we might quickly get this running.
Feel free to contribute to this repository or fork it.

No, is there a lot of special things to consider? Do you think it might be easier to build it with twrp 11?
I thought since it is now the default branch (12.1), it should be the one to use.

1. Yes, especially concerning environment for builds and also the difference between 11/12 FBE Data encryption etc; 2. No, that URL was about 12.1, but to read You must register and log in. Than You will see a desperate battle and necessary things to keep in mind. There You will find the results for TWRP 12.1 for some Google Pixel's.
Also, in other thread of XDA I've seen LOS 19.1 and TWRP 12.1 ready to use for one of Samsung Galaxy (S8 ?), but seems it includes some proprietary Samsung SW. May be You can ask there for details ? The Developer, Ivan Meler, is friendly and communicative.

Alright so....
All Galaxy S series except the Galaxy S6/S6 Edge have got the Android 12 Custom ROM's made for them. Can anyone make an Android 12 custom rom for this device? It will be highly appreciated. Thank you!
I don't think anyone is actively developing for the S6 anymore. May be eventually someone will build A12L, but at least for now, dont get your hopes up

Oiii....I tried the gsi's. Unfortunately, there was no success. The phone was bootlooping continuesly. Most Android 12 gsi's are for "a/b type partition only" and the S6 is "A only type". That's the reason why it won't work. I guess....We'll have to wait for the Dev's to make an android 12 rom for this device.

Alot of people still use the S6 to this day, even I have it as my secondary phone. It's running evolutionx (android 10) and it's absolutely a beast, it works buttery smooth. So smooth infact that it can beat a midrangers with ez. I can't imagine how cool it would be to run a12 on a phone that's almost 7 year old at this point. Hopefully, Some dev could give a new life to this device again.

Hello everyone,
i want to install a custom rom for my device tecno spark 8c because the stock rom is so trash like ads limit apps i hate it i tried to search for a custom rom for my device and i didnt find any resource or link for existing custom rom for my device does any one know where i can find or if there is one i will be greatfull and thanks
While there is no custom ROM's for your device, your next bet should be GSI's or Generic System Images. These are ROM's with a one-size-fits-all design. Maybe you can search around for a custom ROM you like and see if they have a GSI available.

Here's a tutorial that I used before: https://www.xda-developers.com/flash-generic-system-image-project-treble-device/
Also, here's a minimal ROM that has a GSI available: https://havoc-os.com/
Do note that you need a GSI that matches or is a higher android version than the current system.

ok i read a little about gsi and project reble so the rom is basicaly a rom that run on anydevice because the vendor or arcitecture kinda separate from software didnt quite understand what i need is that my device to meet the terble project requierments so i am able to install it.
ok so here i found this link
https://www.getdroidtips.com/android-12-tecno-spark-8c-kg5k/
i find it before i create this thread and it shows gsi first i didnt want to use it because the rom source unknown for me i didnt know gsi and anything else i was not trusting it
ok so now if i want to search a good gsi rom compatable with my device other than this i want to know if my device compatable with project treble where can i see that and what famuos roms are have this kind like lineage ,and similar to havoc so i find the i like its features and compatble
