First, choose the release—not the nickname

Decide whether you are working with LMC 8.4 R18 or R17. Hasli’s R18 page currently lists six files carrying R18F1 in their filenames; the R17 page lists five files carrying R17. A file from one release is not interchangeable with a same-named variant from the other. Read the full filename and the Android package ID beside it on the release record before downloading.

The R18 file list includes Standard, Snapcam, Aweme, Scan3D, Google Lens and Iris. The R17 list includes Standard, Snapcam, Aweme, Scan3D and Google Lens. The R17 page also discusses other package names in its explanatory notes, but a name in the notes is not an available R17 download. When in doubt, follow the actual links in the release’s download list. The LMC 8.4 starting page puts both releases side by side.

What the package name can change

Android uses a package ID as an app’s identity. A file named Snapcam in LMC 8.4 R18F1 uses org.codeaurora.snapcam; the Scan3D file uses com.samsung.android.scan3d. This does not mean one contains a special image-processing engine. It means Android and the phone’s camera policy may treat it as a different app. On some devices, one identity can reach an ultrawide or telephoto camera that another cannot. On others, changing the identity makes no difference.

Different package IDs can also allow two camera ports to coexist, while files with the same ID may conflict with an installed app. An ID alone does not establish whether an update will install over an existing APK: signing identity matters too, and this site has not measured it for the origin files. Save your working settings before experimenting. Do not uninstall a reliable camera just to make an untested variant fit.

A sensible starting choice

You have no device-specific evidence: start with the Standard file for the release you chose. It creates a baseline. If it opens and captures from the cameras you use, there may be no reason to try another package.

The main camera works but an extra lens is absent: check the camera settings and any exact-model report first. Then a different identity can be tested as a single controlled change. Upstream GCam guidance notes common associations: Snapcam with some Snapdragon-based phones, Scan3D with some Samsung devices, and Aweme with some Realme, OPPO or OnePlus devices. These are examples from the port ecosystem, not a compatibility list for LMC on your exact model.

An app with the same package ID is already installed: record what that app is and whether you want to keep it. An alternate identity may avoid a direct conflict, but it can behave differently with the camera hardware. Do not assume that changing the file’s visible name changes its package ID; check the ID shown by the origin.

You already have a stable R17 setup: a move to R18 is a release change and may also be a package change. Test those variables separately where possible. The R18 notes emphasize interface and control changes rather than an automatic image-quality increase.

Read the exact file list, not just the brand hint

A “Samsung package” is shorthand for a particular Android ID, not a promise that every Galaxy camera will open. The same caution applies to “Snapcam for Snapdragon.” A manufacturer can ship different hardware by region, and a firmware update can alter third-party camera access. The most useful evidence names the exact model code, Android or ROM version, LMC release, selected file and tested camera action.

When a phone guidance search has no matching record, do not turn the absence into a positive or negative claim. It means this site has not documented the combination. If you choose to test, the checklist below helps you keep the result interpretable. A report that says “LMC works on my phone” is much less useful than one that says which package opened which lens and whether the saved photo was correct.

Test one package in a way you can repeat

Write down the exact model code and Android version. Keep the APK filename and package ID with that note. Test the app before importing any XML, because a config introduces another variable. Take one photo through the main camera, one through the front camera, and one through each extra lens you care about. Check that each file saved and that the lens used was the one you selected. If video matters, record a short clip separately. Then note any failure in plain terms: install error, app closes, black preview, missing button, capture hangs, or wrong lens opens.

If the first package fails, change only the package identity and repeat the same checks. If you also change Android settings, release and XML at the same time, you will not know what caused a different result. Keep the stock camera available throughout the experiment. The goal is a camera setup you can use and reproduce, not a badge that merely says “compatible.”

Before you allow an APK to install

Compare the recorded variants on the R18 or R17 page. Direct file-specific APK links are available for the recorded variants. This library has not independently measured file hashes, signatures or malware-scan results, so those fields remain unclaimed. If Android or Play Protect displays a warning, read it and check the origin before proceeding. We do not advise disabling Play Protect; Google explains how Play Protect checks apps from other release details.

Package-choice questions

Is Snapcam a better-quality LMC build?

No quality advantage follows from the name. It is a package identity for a given release. Whether it changes lens access depends on your phone.

Should every Samsung user download Scan3D?

No. Scan3D is one recorded option. The Samsung guide explains why exact model, region and software details matter more than the broad brand.

Can I install every variant at once?

Different IDs can sometimes coexist, but that does not make installing every file useful. Start with one, test it and keep a record. A conflict or Android policy can still prevent a particular installation.

Can a package name fix a black preview?

It may be one variable worth testing, especially if the main camera works and an auxiliary one does not. A black preview can also involve device camera access, settings or an imported XML. Isolate the first failing step before changing several things.
