You cannot browse the /data/data/ folder without root, but you can extract a full app backup.
Viber uses a simple XOR cipher with a per-device key. Tools like ViberAudioExtractor (open source on GitHub) can brute the key because the header pattern is predictable. Rename the file to .m4a after decryption.

Unlike WhatsApp or Telegram, Viber does not offer a simple "Save Audio" button. The app treats voice messages as ephemeral, temporary files. But "ephemeral" doesn’t mean "unavailable."
# Viber's simple XOR key (found via reverse engineering) key = [0x7A, 0x3C, 0x5E, 0x1D, 0x8F, 0xA2, 0x4B, 0x9C] You cannot browse the /data/data/ folder without root,
Navigate directly to: /data/data/com.viber.voip/files/ Look for the VoiceMessages folder. Copy all .enc files to your PC and run the decryption script. Method 2: iOS (The Screen Recording Workaround) On iPhone, due to the sandboxed file system and lack of user-accessible app directories, you cannot extract the raw file without jailbreaking (not recommended).
If you’ve ever received a heartfelt voice message from a grandparent or a critical business note on Viber, you’ve probably asked: How do I save this? Rename the file to
