What is LMC 8.4?

LMC 8.4 is Hasli’s Android camera port based on the Google Camera 8.4 family. It combines camera controls with XML settings that can be tailored to a phone.

Think of the APK as the camera app, the package as its Android identity, and the XML as a saved group of settings. They solve different problems. A new package can help a supported phone expose an extra lens; a matched XML can restore processing and camera settings. Neither replaces your sensor or automatically makes every picture better.

The R18 source credits other GCam developers and describes a mod heavily based on SGCam. This is an independent guide to those releases. Start with the main rear camera at default settings, then adjust a working setup rather than importing several presets at once.

Which is the latest LMC 8.4?

The inspected 8.4 release source lists R18F1. Newer-numbered 8.8 and 9.6 camera bases are separate branches. R18’s notes describe changes to controls and usability, with no claimed quality change.

A USEFUL FIRST SETUP

Choose your starting point.

A filename is only the first step. Choose the path that matches what you are trying to do.

I am installing for the first time

Find your exact phone

Match the model, regional variant and stock/custom firmware. Read the source’s package and XML notes before deciding which artifact to try.

I installed it, but something fails

Identify the failing step

An installer error, empty XML chooser and auxiliary-lens crash have different causes. Test defaults first and change one variable at a time.

SEPARATE OWNER-PROVIDED FILE

Download the owner-provided APK

This file was supplied by the site owner. Its Android manifest reports version 1.0.0 and package com.lmc84.app.

Release unverified

This entry is separate from the sourced Hasli releases. It has not been identified as R18F1, R17 or another release in this guide. Device and XML recommendations for those builds do not establish compatibility with this file.

The manifest declares a minimum of Android 7.0 (API 24). This is a file requirement, not a real-device compatibility result. The Android APK installation steps explain the installation process.

One release. The right package.

LMC 8.4 download choices depend on your phone’s firmware and camera access. Package names can matter; they do not promise universal compatibility.

R18F1 has six source-listed variants. Older releases have their own file sets. Check the package guide and device evidence before choosing.

Hasli release links are not configured

The owner-provided APK is listed separately above. These source-listed release variants still need their own matching download URLs.

02 / INSIDE LMC

See where the camera controls live.

Use the annotated historical viewfinder to recognize the shutter, modes and lens controls, then read the notes for your installed release.

Historical LMC 8.4 R13-source viewfinder, with annotations identifying controls
Genuine viewfinder screenshot from the R13 release page; annotations are ours. It does not show R18 or prove the pictured lenses work on your phone. View full screenshot.

Find the control before changing the setting

  1. Processing controls. The pictured top row includes frame count and AWB. Find the matching controls in your own build; a profile may change which buttons appear.
  2. Lens selector. A button can select a camera or a zoom setting. Check whether it opens a real, usable lens on your phone instead of assuming a visible “2” means telephoto hardware.
  3. Shutter. Capture a default main-camera photo first and confirm it saves. This gives you a baseline before importing XML.
  4. Capture modes. The source image shows Night Sight, Portrait, Camera and Video. Test each mode separately; a successful Camera photo does not establish video or Night Sight support.
Why does my screen look different?

LMC releases and XMLs can expose different buttons. R18 changes control placement and popup menus. Use the release-specific notes and save your current XML before reorganizing settings.

See settings screens and the R18 button legend
FROM A SETTING TO A PICTURE

Learn what the controls actually do.

The point of a camera port is a usable capture workflow. These are starting ideas to test on a working phone, not universal presets.

Several differently exposed illustrative frames contribute to one processed image
Concept diagram of multi-frame processing. It is not an LMC capture or a recommended frame count.

GCam’s HDR modes and processing tradeoffs are explained in the GCam technical FAQ. Mode availability still depends on the port and phone.

Choose speed or a steadier capture

HDR+ Enhanced combines multiple frames. It can be useful when a still scene contains bright sky and darker foreground, but it takes more time than a faster capture mode. With a moving person, try the faster available mode and check whether faces remain sharp.

Night Sight also needs time and stability. Astrophotography depends on darkness, a stationary phone and device exposure support. A menu option does not prove your firmware supports a long exposure.

Change processing with a purpose

White-balance controls alter color interpretation; sharpness and noise settings alter the tradeoff between texture and smoothing. Save a backup before changing them. Compare the same scene and lens so a lighting change is not mistaken for a preset improvement.

Landscape or buildings

A still scene with bright areas

Keep the phone steady, meter deliberately and compare a faster HDR mode with HDR+ Enhanced if both work. Inspect the bright sky and shadow detail before choosing.

People and movement

A faster capture can matter

Watch for motion blur, delayed capture and unnatural skin color. Keep the same lens and distance when testing an XML, and avoid assuming a portrait label guarantees a good edge mask.

Low light

Stability comes before a preset

Support the phone and give the selected mode time to finish. Test a normal photo and Night Sight separately; failure in one mode does not establish failure in every mode.

Illustrated stationary landscape, moving subject and low-light scene
Original scene guide. Choose a capture workflow for the subject; these are not measured LMC results.

Two more terms you will see in configs

AWB: a color choice, not a megapixel setting

Auto white balance estimates the color of the light. Different calibration/models can make a scene warmer, cooler or more neutral. Compare AWB on/off with a familiar neutral object and skin tones in daylight and indoor light, rather than judging only sky saturation. See the Google Research explanation; Pixel calibration does not establish identical accuracy on another phone.

RAW/DNG: a file for an editing workflow

A JPEG is a rendered image ready to view; RAW/DNG holds raw image data and camera metadata for compatible editing software. If your build and camera offer RAW + JPEG, check that both files save and open. A RAW thumbnail is not the same comparison as a developed image. See Android’s DNG reference and Google’s format explanation; these sources explain formats, not universal LMC support.

Keep the stock camera available.

Use whichever app reliably provides the lens, video mode or fast capture you need. This guide does not establish a universal LMC-versus-stock winner or a measured photographic improvement.

03 / YOUR PHONE

Start with your exact model.

Find a community-listed XML and read its hardware, firmware and package caveats before installing.

3 featured devices. Community evidence; check the variant details.

Community XML referenceFounder-reported APK testing

Samsung Galaxy S20 FE

Start here

Confirm the regional hardware variant first. On the source's Snapdragon target, start with 25_4_23_setting_preference.xml and an unchanged photo mode before comparing the more customized file.

Choosing the config

Choose the simple Snapdragon-labelled entry to establish a reference. If you try the jrosatti profile, its source describes tele, ultrawide, wide, front and wide black-and-white controls plus tone-curve/upscale changes; check each control's actual saved output.

Model-specific setup checks

Read the exact S20 FE variant

Use the full model number and regional specification rather than the S20 FE product name alone. The Snapdragon-labelled recommendation is not evidence for an Exynos S20 FE.

Keep effects separate from lens tests

With the jrosatti profile, test ordinary wide output before black-and-white or upscaling. That makes it easier to tell a lens-switch problem from a deliberate processing effect.

Use the older basic file as a controlled alternative

The older s20fe_snap_lmc8.4r15_basic.xml has model and Snapdragon labels. Keep its R15-index scope visible, and change only the XML when comparing it with a working setup.

Test in this order

  1. Save a daylight main-camera reference with the simple profile.
  2. Try every exposed front/auxiliary control and confirm that the saved view changes.
  3. With the custom profile, compare wide color and wide black-and-white separately; check file size if upscaling is enabled.

Keep separate: Exynos S20 FE for Snapdragon-labelled files; Galaxy S20; Galaxy S20 Ultra

Samsung Galaxy S21 Ultra

Start here

For an Exynos phone considering the older profile, plan around the documented front-camera limitation. For HK-Leica, check the 3x night result early instead of evaluating only daylight main-camera photos.

Choosing the config

The current HK-Leica entry provides a concrete zoom/night warning but leaves chipset scope unspecified. The older Exynos entry is clearer about hardware and front-camera behavior; neither establishes a complete all-camera setup on every firmware.

Model-specific setup checks

Test the known 3x case

Take the same low-light subject with 1x and 3x, then inspect the saved brightness. If HK-Leica's 3x picture is too dark, retain another working option for that situation.

Check selfies before choosing an everyday profile

The source specifically reports that the older Exynos S21U-R15-HDR profile does not support the front camera. Keep the stock-camera selfie path available if that limitation appears on your phone.

Do not infer chipset from the Leica label

HK-Leica is a contributor profile name. Resolve the phone's variant and verify lens behavior rather than treating that name as a Snapdragon or Exynos assignment.

Test in this order

  1. Compare main-camera daylight color with the stock camera.
  2. Check 3x under dim light using the same subject and position.
  3. Switch to the front camera and save a photo before relying on the setup.

Keep separate: Galaxy S21; Galaxy S21 FE

Why does the S21 Ultra 3x camera look darker at night with HK-Leica?

The contributor identifies darker 3x night pictures as a known profile issue. Compare a main-camera shot and retain a working alternative for the scene; this website has not measured the effect.

Profile source / instructions ↗ Profile source / instructions ↗

Variant limits and source evidence (2)

The current HK-Leica profile does not specify chipset. Its source reports darker 3x zoom images at night. The older S21U-R15-HDR profile explicitly targets Exynos; its source says rear cameras work but the front camera does not.

Samsung Galaxy S22 Ultra

Start here

Identify Snapdragon or Exynos before importing the older profile: S22U-SD-LMCr15-ArcideV7.xml and LMC-S22U-Exynos.xml are separate choices.

Choosing the config

Use the explicitly labelled older hardware entry when you need a clear variant match. Treat the newer javasabr profile as a separate community experiment whose chipset and release scope require confirmation.

Model-specific setup checks

Keep two hardware profiles apart

Name saved backups with SD or Exynos alongside the APK release. This prevents an accidental cross-variant import when several S22 Ultra files are in the same folder.

Separate S22 Ultra from S22/S22+

The index has a different S22/S22+ heading. A base-model R18 assignment cannot be transferred to the Ultra listing simply because both say S22.

Follow the package note at its documented scope

The older S22 Ultra section recommends ruler or scan3d. After installing a matching build, establish main-camera photo saving before trying auxiliary buttons.

Test in this order

  1. Load the file whose explicit hardware label matches the phone.
  2. Save main and front photos, then test each exposed rear lens.
  3. Compare the newer profile only after preserving the working hardware-specific setup.

Keep separate: Galaxy S22; Galaxy S22+; Opposite chipset variant for SD/Exynos-labelled files

Which S22 Ultra XML should I use: Snapdragon or Exynos?

Match the phone's regional hardware variant to the explicit source label. The files are separate, and this catalog does not establish that one substitutes for the other.

Profile source / instructions ↗ Profile source / instructions ↗

Variant limits and source evidence (3)

The newer index profile does not specify regional chipset. The R15 index provides separate Snapdragon and Exynos files; keep those separate. A package choice cannot remove all hardware and ROM differences.

08 / HELP & ANSWERS

Get a working starting point.

What is the latest LMC 8.4 release?

The inspected Hasli hub’s latest 8.4 listing is R18; its source page currently lists R18F1 files. LMC 8.8 and 9.6 are separate branches, so “latest 8.4” does not mean latest LMC overall.

Is LMC 8.4.300 a different download?

The inspected primary release pages establish the 8.4 family but do not confirm the exact upstream patch number 8.4.300. Choose by the full Hasli release filename and package ID; the number alone does not identify a separate verified artifact here.

Does every Android phone support LMC?

Firmware, camera access, chipset, release and XML matter. Muzamil Ahad reports APK testing across the listed models; individual phone-test records are not published. The 40-model catalog retains community source notes and firmware limits so you can check your own setup.

Does a DSLR, iPhone color or Leica XML change the camera hardware?

No. These are photographic looks or community labels. They do not replace the sensor or optics and do not indicate affiliation with those brands.

What does “r17 camera” mean here?

In this guide it refers to the LMC 8.4 R17 camera release. The phrase can be ambiguous outside that context. Use the R17 release page to check the exact filenames and changes.

Are “lcm8” and “lic camera” separate LMC apps?

These phrases can be ambiguous. If you intended Hasli’s Google Camera port, its name is LMC and the source identifies releases such as LMC8.4_R18F1. Use the actual release and package names to avoid choosing an unrelated app.
