How to Choose the Best LMC 8.4 for Your Phone

Follow this simple method:

  • Install version
  • Open camera
  • Test HDR
  • Test Night Sight
  • Check for crashes

Step 4: Use Proper XML Config

Most issues happen because users don’t load correct config file.

Common Problems When Choosing Wrong Version

If you install wrong version, you may face:

1. App Crashing

Mostly on unsupported processors.

Always prioritize stability over new features.
