v1.9.8

Added

• Enterprise-Grade Mobile Security & App Lock:
  • Exclusive to Mobile devices (strictly disabled on Android TV), disabled by default.
  • Mutually exclusive security modes: 4-Digit PIN, Custom Alphanumeric Password, or Device Biometrics (Fingerprint, Face Unlock, Device PIN/Pattern).
  • Hardware & enrollment check automatically detects biometric capability and dims/disables the option when unavailable or not configured in Android Settings.
  • Setup flow provides an Irreversible Lockout Warning dialog and generates a 16-character alphanumeric Recovery Key with a 60-second clipboard auto-clear security rule (matching Encrypted Vault).
  • Modify credential flow requiring confirmation with current PIN or Password before updating.
  • Secure disable verification requiring active PIN, password, or biometric authorization before clearing credentials.
  • Dedicated full-screen SecurityUnlockActivity protected by FLAG_SECURE (blocks screenshot and recents preview leakage) and back-button minimization.
  • Anti-brute-force rate limiting: 5 consecutive failed attempts trigger an automatic 30-second lockout timer.
  • "Forgot PIN or Password? Enter Recovery Key" reset flow allowing credential restoration without app reinstallation.
  • Lock frequency options: "On new / fresh open only" (default), "Immediately on background", "After 1 minute", and "After 5 minutes".
  • Created professional cyber-shield padlock vector (ic_security_lock) registered across icon customization, export, and settings.
  • Disclosed App Lock storage specifications and irreversible lockout policies in English strings, WEBSITE/UFMPrivacyPolicy.html, and WEBSITE/UFMTerms.html.
• Mobile Header Options Menu: Added "Copy Folder Path" option between "Twin Window" and "Settings" when browsing Local, SAF, Network, and Online storages, instantly copying the full folder path to the clipboard with confirmation feedback.
• Checksum & Hash Verification Tools for Mobile and Android TV:
  • Generate CRC32, MD5, SHA-1, SHA-256, and SHA-512 hashes for single and multiple files in a single pass.
  • Multi-storage support across Local storage, SD cards, USB drives, SAF locations, Root storage, Network shares (SMB, FTP, SFTP, NFS, WebDAV, DLNA), Cloud storage, and archive contents (ZIP, 7Z).
  • Live paste verification field with auto-algorithm length detection and visual match/mismatch status indicators.
  • Twin Window dual-pane file comparison with size-difference early exit and content hash verification.
  • GNU coreutils manifest file export (.sha256, .md5, etc.) and batch manifest import verification checklist.
  • Integrated into Settings -> "Long Press Toolbar Icons" (Tools & Media section), Mobile Floating Quick Action Bar, TV selection action bar, and Settings Backup & Restore.
  • Added new cryptographic shield and hash vector icon (ic_checksum) with full icon customization palette and icon pack export support.

Fixed

• Fixed an issue where Material You dynamic wallpaper colors failed to apply in AMOLED Black mode on Android 12+, causing UI accents to stick to the standard fallback color instead of the dynamic system palette.
• Fixed rooted external application edit / sharing permissions error.
• Fixed an ANR (freeze) on Android TV devices when launching the SAF document picker (SafPickerActivity) on cold start by offloading storage volume queries, network share loading, and local directory scanning to background coroutines, and added ANR watchdog filter 64 for cold-start OverScroller animation completion.
