[Magisk Module] Enable RAW capture for GCam

[TBM 13]

This Module enables RAW Capture on the Galaxy A30, 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. It's for the A20, but contains useful information.

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.
• Camera freezes in X app
  • This may be caused by this module. If it does, the only fix is to remove/disable it. So far I've only experienced this in a single app that scans QR codes.

Does this work with aosp based roms? Or is it just one UI?

Yes, it works with AOSP.

What kernel you recommend to use in gsi ROM with this module?

I don't know much about kernels for the A30. In my A20 with an Android 12 GSI i use stock kernel with some small modifications (dmverity disabled, MTP fixed for AOSP, etc.)

bro, you can enable 60fps FHD record for our devices?

Wow, that seems like an promising approach ! Keep up the good work.
Any chance the patcher can be extended to Galaxy S10/20/21 ? or is that a completely different topic ?

Probably, I would have to check their libexynoscamera3.so library.

I just checked the library of the Galaxy S10 and yes, it should be possible. However, doesn't it already support RAW?

On the stock rom it probably does.
For the S10/20 on LOS only standard and wide lens are accessable whereas the telephoto is not.
On the S10 for LOS 17.1 I therefore had a patched "libexynoscamera3.so" as well granting access to telephoto lens via gcam.

However for LOS 18.1/19.0 or even for my new phone the S20 I was not able to find any patched libs anymore since nobody took the effort of reverse engineering it as you did.

Would you be willing to make the necessary adaption for your patcher to successfully enable raw on all lenses for LOS 18.1/19 on the S10/20 ?

Sure. Do you have Telegram?

Bro, you can make this mod for Android 10 vendor?

 

[TBM 13]

Bro, you can make this mod for Android 10 vendor?

Technically, yes. However, in the A20 enabling RAW in the Android 10 library makes the camera freeze after some seconds in apps like GCam.

If you are willing to test, i can do it, maybe the A30 doesn't have the same issue.

Bro will this mod work for Galaxy A30 (Android 11) ??
Edit: I'm sorry....for a moment I thought this mod for A20.....Sorry again.

 

[SirKosichka]

this mod work for Galaxy A30 (Android 11) ??

Yes, only on gsi or Oneui3.1 ROMs.You need ROM with 11 vendor

 

[TBM 13]

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.

That's not really helpful. What is happening to make you say it doesn't work, black screen? What ROM are you using? What kernel? What vendor, the one that comes with the ROM, stock Android 11 vendor or a custom one? What camera apps did you try?
