I say this because -- according to the company's official response[1] -- the recordings were only created on the Android version and not the iOS version of their app.
They also state that the recording is only cached locally on the phone and not uploaded to their servers.
Leads me to think that it's very likely their Android app programmer(s) wrote some test code to save the file, and forgot to delete it or conditionally hide it in their release version of the App. There's no excuse for the sloppy programmer(s) if this was the case, I'm just saying the 'bug' angle is a possibility, because the Company has also been very quick to fix it and release an updated version for the Andriod app.
One more thing, I wouldn't call something like this a 'minor' bug. Likely their PR team threw that word in.
