Hasli LMC 8.4 Samsung / Exynos

This is a GCam port specifically for Samsung devices which is of base version 8.4.300 and LMC version vR18 (latest) which is built by Hasli based on Arnova8G2 and BSG GCam 8.4.

Build date: July 2022

Many of the changes might not applicable to Samsung Exynos but it still might have some relevancy.

Changelog of LMC8.4_R17 by Hasli:

  • TEST patcher: LDR Lite Highlight, Sabre Noise, Disable Preserving Highlights (Disables the limit on the appearance of highlights, works in conjunction with the HDR Ratio).
  • Gain section with new Radius Gain. (To activate the radii, the main Sharp Gain must be greater than 0).
  • Samsung Mettering Mode in the System Setup section (Thanks iDan).
  • Other fixes.

Changelog of LMC8.4_R16 by Hasli:


  • Added selection of the number of frames to be glued in ZSL / HDRNet (divided by modules) (processing functions) *3.
  • Long Tap with Function Selection (Viewfinder Settings) *1.
  • Added zoom value selection per button (system settings) *5.
  • Added low / high viewfinder resolution switch (LMC tweaks).
  • Added exposure slider view toggle (LMC tweaks).
  • Several new presets for subtle noise levels.
  • Removed the number of frames button and added a Julian T color transformation button.
  • Added HDR effect item to the Exposure Compensation menu.

Corrections made:

  • Fixed merging on all interfaces, disabled the minimum threshold for merging frames (from 1 to 28, 28 is limited by the principle - it will work for everyone).
  • Fixed exposure slider in HDRNet.
  • Fixed front camera on some devices (1+6, 1+7, etc.) incl. library loading *6.
  • Fixed some bugs that could occur when using different interfaces.
  • And other code changes.


  1. 28 frames limit is purposeful, most devices are limited by such a buffer, and so that there are no disagreements in the config, I specified this limit.
  2. In Release 16, the settings for selecting noise models, upscaling, black level settings, Julian CT have disappeared. - to re-expose and check by yourself.
  3. In release 16 there are a lot of changes in the code part, new problems may appear. But for the most part, it's all good.
  4. All main functions are checked through debugging and by the community before the release, if something does not work for you - the problem is in the config with a probability of 90%.

Code or ideas borrowed from: 1* PZD, 2* LMC8.2(Rashid), 5* x9s, 6* sgcam, 3* dpeasant3, 4* artiushkin.
I also express my gratitude to good friends for feedback and help :)

Old Configs:
- Some parameters on old configs have gone off (noise model, upscale, black level) need to be set again on your configs.

Changelog of LMC8.4_R14 by Hasli:

  • Material You for all versions of Android. *
  • Noise model from the system and noise model tuning. *
  • Disabled 70% of animations for speed.

* Taken from SGcam, thanks to Shamim for a job well done.

Clean installation recommended. Configs from previous versions are still supported on this version as well.

The noise model setting does not work with the system model, nor does dynamic ISO selection work in noise models. It will be fixed in a future update.

Changelog of LMC8.4_R13 by Hasli:


  • ISO100, Max.Time, Max.ISO in shutter speed selection.
