Ringtone Switcher

Say goodbye to repetitive, monotonous ringtones! "Ringtone Switcher" is a smart local ringtone rotation tool crafted specifically for Android users. Simply select and import your favorite songs stored on your device, and the app will automatically and seamlessly switch to the next ringtone after every phone call!

✨ Key Highlights & Features:

🎧 Freely Import Local Music
Read audio files directly from your phone's storage! Full support for mainstream formats including MP3, M4A, OGG, and WAV. No longer limited by system default ringtones—build your personalized incoming call playlist.

📱 Dual SIM Independent & Synced Switching
The ultimate solution for dual SIM phones! Supports SIM 1 and SIM 2 independent playlists and rotation modes, or check "SIM 2 uses SIM 1 Ringtone" with a single tap for effortless synchronized management.

🎶 Sequential Rotation & True Cryptographic Random
Supports both "Sequential List Rotation" and "Cryptographic Anti-Repeat Shuffle" modes. Even if you switch from shuffle back to sequential playback midway, the system intelligently continues with the next track without restarting from the first song.

📁 Smart Playlist Management & Health Check
Supports batch selection, deletion, and duplicate-free cross-SIM copying. Built-in file health check automatically alerts and safely skips missing or moved audio files, ensuring your incoming call ringtone always works reliably.

🗑️ 24-Hour Recycle Bin Protection
Accidentally deleted a song? No worries! Deleted tracks are safely retained in the Recycle Bin for 24 hours, allowing easy one-tap restoration at any time.

🚀 Auto-Start on Boot & Zero-Delay Standby
Automatically validates playlists and mounts the initial ringtone upon device reboot. The status bar displays the currently prepared ringtone in real-time. Accurately switches ringtones in the background even when your screen is off, in sleep mode, or under battery saver.

🛡️ 100% Local Operation, Zero Privacy Uploads
No account registration required. All settings and audio files stay strictly on your local device. The phone state permission is strictly used to detect ringing and call completion to trigger switching—never reading, recording, or uploading your call logs or contacts. Your privacy is 100% protected!
