Copy or move the downloaded .xml file into:

Internal Storage → LMC8.4 → Configs

If the file is inside a subfolder (e.g., Downloads/), move it out. The LMC8.4/Configs folder must contain the .xml directly.

Result: The app will flicker or restart. You will now see custom toggles (e.g., "Saturation," "Lib Patcher") appear. Your GCam is now optimized.

Google Camera (GCam) has revolutionized mobile photography, and among the countless mods available, LMC (Lukas Modded Camera) stands out as a fan favorite. Specifically, LMC 8.4 R18 (based on GCam 8.4) is renowned for its exceptional dynamic range, natural color science, and advanced manual controls.

However, to unlock the true potential of LMC 8.4 R18 on your specific smartphone, you need more than just the APK. You need a configuration (config) file. These .xml files are pre-tuned settings mapped to your device’s sensor (e.g., Sony IMX586, Samsung ISOCELL HM3, etc.).

This article provides a step-by-step guide to downloading and installing the correct LMC 8.4 R18 config file for your phone.

Example: LMC8.4_R18_Pixel6a_v5.xml or LMC_R18_IMX586_NightMode.xml

Do not rename the file arbitrarily, but ensure it ends with .xml.

This guide shows how to download and install the GCAM LMC 84 R18 config file for Google Camera (GCam) ports, including verifying compatibility and applying the configuration for best results.

Answer: No. LMC 8.4 R18 config files work on non-rooted devices. You only need to create the LMC8.4/Configs folder in internal storage.
