1.3.12 (Dec 10, 2025)

📝 Summary

Memory optimization for issue reporting to prevent OOM crashes.

🐛 Problem

reportIssue stored failed reports with base64 images in SharedPreferences. SharedPreferences loads entirely into memory. 10 reports × 200KB images = 2MB+ in memory = OOM crashes.

✅ Solution

Store images as files. SharedPreferences stores only file paths (~100 bytes each).

Memory savings:

  • 10×200KB images: 23.14 MB → 7.41 MB (67% reduction)
  • Peak heap: 27.28 MB → 11.82 MB (57% reduction)
