If the front camera is not working in LMC 8.4, you’re definitely not alone. Many users report that the rear camera works perfectly while the selfie camera shows a black screen, crashes, or fails to switch.
This issue is common in GCam mods because front camera support varies widely between devices and camera sensors. The good news is that in most cases, the problem can be fixed with the right settings.
In this complete troubleshooting guide, you’ll learn the real reasons why the LMC 8.4 front camera fails and the proven fixes that work on most Android phones.
Common Signs of Front Camera Problems
First, confirm your issue matches one of these.
Typical symptoms
- Black screen on selfie camera
- App crashes when switching cameras
- Front camera option missing
- Preview freezes
- Selfie photos not saving
- Portrait front camera not working
If you see any of these, follow the fixes below.
Why the Front Camera Fails in LMC 8.4
Unlike the main camera, the selfie camera is more sensitive to compatibility.
Most common causes
- Wrong interface model
- Unsupported auxiliary camera settings
- Incompatible XML config
- Camera2 API limitations
- Incorrect stream configuration
- Device-specific restrictions
- Using wrong LMC build
Fortunately, many of these are fixable.
🔍 Quick Checks (Do First)
Before deeper fixes:
✅ Restart your phone
✅ Close the stock camera app
✅ Ensure permissions are granted
✅ Test rear camera first
If the rear camera works but front does not, continue below.
🛠️ Fix 1: Change Interface Model (Most Effective)
This is the #1 fix for front camera issues.
Steps
- Open LMC 8.4
- Go to Settings → Advanced
- Tap Interface Model
- Try these options one by one:
- Pixel 5
- Pixel 6
- Pixel 4 XL
- Force close and reopen the app
Many devices enable the front camera immediately after switching.
🛠️ Fix 2: Enable Auxiliary Cameras
Sometimes the selfie camera is disabled in settings.
Steps
- Open LMC Settings
- Go to Advanced / Developer settings
- Look for Auxiliary cameras
- Enable all available cameras
- Restart the app
Not all builds show this option, but when present it helps significantly.
🛠️ Fix 3: Remove or Replace XML Config
An incompatible XML often breaks the front camera.
Quick test
- Clear app data
- Open LMC without loading XML
- Switch to front camera
If it works now, your config is the problem.
Solution
- Use device-specific XML
- Try balanced config
- Avoid over-tuned configs
🛠️ Fix 4: Check Camera Permissions
Missing permissions can block the selfie camera.
Required permissions
- Camera
- Microphone
- Storage / Photos
Verify
- Go to Settings → Apps → LMC 8.4
- Tap Permissions
- Enable all required permissions
- Restart the app
🛠️ Fix 5: Clear Cache and App Data
Corrupted settings can affect camera switching.
Steps
- Go to Settings → Apps → LMC 8.4
- Tap Storage
- Press Clear Cache
- Press Clear Data
- Reopen the app
Test the front camera before loading XML again.
🛠️ Fix 6: Try a Different LMC 8.4 Build
Some builds handle front cameras better.
When to try
- Rear camera works but front fails
- App crashes on switch
- Selfie mode missing
- Only certain modes fail
Solution
- Install another LMC 8.4 variant
- Use stable release
- Prefer builds recommended for your chipset
Often this resolves compatibility issues.
🛠️ Fix 7: Check Camera2 API Support
Front camera support depends on Camera2 implementation.
Use a Camera2 API checker
Look for:
- Level 3 → Best support
- Full → Good
- Limited → May work
- Legacy → Front camera likely unstable
Devices with Limited support may have partial functionality.
🛠️ Fix 8: Test the Stock Camera
This helps identify hardware limits.
Quick test
- Open stock camera
- Switch to front camera
- Take a selfie
If stock camera also fails
The issue may be hardware or system-level, not LMC.
⚠️ Devices More Likely to Have Front Camera Issues
Some phones require extra tweaking.
Higher risk devices
- MediaTek processors
- Older Exynos models
- Budget phones
- Devices with limited Camera2 API
- Heavy OEM camera restrictions
These may need trial and error.
📊 Signs the Problem Is Fixed
You’ll know the front camera is working when:
✅ Selfie preview appears
✅ Switching cameras works smoothly
✅ Photos save correctly
✅ Portrait front camera works
✅ No crashes occur
At this point, your setup is stable.
🧠 Pro Tips for Stable Selfie Performance
- Use stable LMC builds
- Avoid random XML files
- Test multiple interface models
- Keep sufficient free storage
- Avoid forcing unsupported features
- Update carefully
Small tweaks make a big difference.
