Android devices play various system sounds, such as screen lock tones, focus notifications, or camera shutter clicks. Recently, I explored an app called Ultimate Sound Control from the Play Store to easily modify these. However, after installation, it caused my phone to restart repeatedly—a common issue reported in reviews. The pro version for custom sound replacement is gone, and the last update was November 24, 2013, indicating it's no longer maintained.
With root access, you can customize these sounds manually and reliably. This method takes a bit longer than an app but delivers results. I'll also cover how to silence specific sounds.

I've successfully used ES File Explorer in Root Explorer mode for this—it's free, intuitive, with a modern Material Design interface. If new to this, open the app, go to Tools in the sidebar, select Root Explorer, and grant root permissions to access and edit system files.
Warning: Modifying system files carries risks, including potential boot issues. Proceed carefully at your own risk, and back up your device first.
From the sidebar's Local section, select the Device tab to reach the root directory. Navigate to /system/media/audio/.
Subfolders like ui, camera, and notifications organize sounds by event (e.g., lock/unlock, low battery in ui). To disable a sound, rename the file from *.ogg to *.oggbak—safer than deleting, in case you want to restore it later.
Note: Avoid deletion to preserve originals for easy recovery.
To replace a sound, convert your track (e.g., MP3) to OGG format using an online converter. Copy the OGG file to internal storage, then to the target folder in /system/media/audio/.
Rename the original file as a backup (e.g., original.ogg to original_backup.ogg), then name your new file exactly like the original. Preview in ES File Explorer, then reboot—changes apply post-restart, similar to refreshing Windows Explorer.
Your Android now has unique system sounds that set it apart!
Bonus: Download sound packs from movies and devices (e.g., Iron Man effects). Extract ZIP files and replace manually, or flash via CWM/TWRP if comfortable—manual is safer for selective changes.
Root tweaks like this unlock personalization but require caution. Questions? Drop them in comments—happy to help based on my hands-on experience.
