LMC 8.4 Keeps Freezing and Stopping – How to Fix

LMC 8.4 keeps freezing mid-shot, then the “Camera has stopped” message appears out of nowhere. It usually happens at the worst moment — right as you’re framing a shot. Five common causes explain most freezes, each with a fix that takes under five minutes.

Why Does LMC 8.4 Keep Freezing and Stopping?

This crash pattern mirrors Android’s ANR (Application Not Responding) system, which force-closes an app after roughly 5 seconds of an unresponsive main thread. LMC 8.4’s heavy image processing pipeline is more prone to hitting this limit on lower-RAM phones than the stock camera app.

Because five different causes produce nearly identical symptoms, the freeze location often narrows down the cause — startup crashes point to config issues, while mid-shot freezes during Night Sight point to processing overload.

The fixes below are ordered by how commonly each cause shows up in user reports, starting with the most frequent: low RAM.

Is Low RAM Causing LMC 8.4 to Freeze?

Low RAM is the most common cause of LMC 8.4 freezing, since its HDR+ and Night Sight processing needs roughly 2GB of available memory to run smoothly during multi-frame merging.

Phones with 3GB or 4GB total RAM, common on budget models from Infinix and Itel, often have under 1GB free after Android’s own background processes, leaving little headroom for LMC 8.4’s memory-heavy processing.

Closing background apps before opening LMC 8.4, especially browsers and social media apps that hold significant RAM in the background, frees up enough memory to prevent most RAM-related freezes.

How Do You Fix LMC 8.4 Freezing During Night Sight Mode?

Reduce the number of frames Night Sight captures in Advanced Settings, since the default 6-frame burst on lower-RAM phones is the single most common trigger for a mid-shot freeze.

Night Sight stacks multiple exposures in memory before merging them into one photo. Lowering the frame count to 3 or 4 reduces peak memory use significantly, at a small cost to noise reduction quality.

If freezing persists even with fewer frames, disable Astrophotography Mode specifically, since its longer multi-frame sequences place the heaviest memory load of any LMC 8.4 shooting mode.

How Do You Fix LMC 8.4 Crashing on Startup?

Clear LMC 8.4’s app data under Settings > Apps > LMC 8.4 > Storage > Clear Data, then reopen the app, since a corrupted startup cache is the leading cause of an immediate crash on launch.

This resets the app to its first-launch state, including camera permissions, so you’ll need to grant camera and storage access again after clearing data.

If the crash happens before the splash screen even appears, the APK file itself may be corrupted — redownloading and reinstalling usually resolves this specific pattern.

Does a Bad Config File Cause Freezing?

Yes, a config file built for a different phone model or LMC version can cause freezing, since it references camera parameters that don’t exist on your specific hardware, forcing the app to hang while trying to apply them.

This typically causes freezing right after loading a config through Settings > Restore, rather than during normal shooting, which helps distinguish it from RAM-related freezes.

Deleting the config and reverting to LMC 8.4’s default settings, then downloading a config specifically labeled for your phone model, resolves this pattern in nearly every case we’ve tested.

How Do You Clear Cache to Fix Freezing Issues?

Go to Settings > Apps > LMC 8.4 > Storage > Clear Cache, which removes temporary processing files without deleting your saved configs or camera permissions.

Unlike clearing app data, clearing cache keeps your saved config and camera permissions intact while removing potentially corrupted temporary files that can accumulate after repeated crashes.

This is worth trying before the more disruptive step of clearing full app data, since it resolves a meaningful share of freeze cases with less setup lost afterward.

Does Background App Activity Cause LMC 8.4 to Stop?

Yes, background apps performing heavy tasks like video calls, GPS navigation, or large downloads compete with LMC 8.4 for both RAM and processor time, increasing the chance of a freeze mid-shot.

Android’s own background app limits, introduced starting with Android 9 Pie, help but don’t eliminate this competition entirely, especially on phones running multiple always-on apps like fitness trackers or messaging apps.

Enabling battery optimization exceptions for LMC 8.4 in Settings > Battery can help the system prioritize it over background tasks during active use.

What Should You Do If LMC 8.4 Keeps Freezing After Every Fix?

If LMC 8.4 keeps freezing after trying every fix above, check your phone’s Camera2 API support level, since incomplete Level 2 hardware support can cause persistent instability that no software fix resolves.

Some budget MediaTek chipsets only partially implement the Camera2 API features LMC 8.4 depends on, which can cause recurring freezes regardless of RAM, cache, or config adjustments.

In these cases, switching to Open Camera or GCam MGC, which have less demanding hardware requirements, often provides a more stable experience than continuing to troubleshoot LMC 8.4.

Conclusion

LMC 8.4 keeps freezing and stopping most often due to low RAM during Night Sight processing or a mismatched config file. Clearing cache, reducing Night Sight frame count, and confirming your config matches your exact phone model resolves the majority of cases we’ve tested.

Why does LMC 8.4 freeze specifically during Night Sight shots?

Night Sight captures and merges multiple long-exposure frames in memory before producing a final photo, which is the most memory-intensive process LMC 8.4 runs. On phones with limited free RAM, this multi-frame merge is the single most common trigger for a mid-shot freeze. Reducing the frame count in Advanced Settings or closing background apps before shooting usually resolves it.

Does clearing LMC 8.4’s app data delete my saved config?

Yes, clearing app data resets the app completely, including any saved config file loaded through Settings > Restore. Clearing cache instead, rather than full app data, removes temporary files without touching your saved config or camera permissions. Try cache clearing first before resorting to a full data reset.

Is LMC 8.4 more likely to freeze on budget phones?

Yes, budget phones with 3GB to 4GB of RAM and MediaTek chipsets with partial Camera2 API support show freezing issues more often than flagship phones with 6GB or more RAM and full Camera2 Level 3 support. LMC 8.4’s computational photography features were originally built for Pixel hardware with more processing headroom than most budget Android phones offer.

Can a phone restart fix LMC 8.4 freezing issues?

Yes, a restart clears all background app memory and gives LMC 8.4 a clean processing environment, which resolves temporary RAM-related freezes. It won’t fix a mismatched config file or incomplete hardware support, though, so if freezing returns quickly after a restart, check those other causes. A restart is worth trying first since it costs nothing and takes under a minute.

Does updating LMC 8.4 fix freezing problems?

Sometimes, if the freezing was caused by a bug in that specific build that a newer version patches. Check Hasli’s release notes for your current version before assuming an update will help, since not every freezing issue is a software bug — many trace back to RAM or config problems that persist across versions. Updating is worth trying alongside, not instead of, the other fixes.

Why does LMC 8.4 freeze only when switching between camera modes?

Switching modes, especially into or out of Night Sight or Portrait mode, triggers the camera hardware to reinitialize, which briefly spikes memory and processor use. On phones already running close to their RAM limit, this spike is enough to trigger a freeze. Closing background apps before switching modes reduces how often this happens.
