lol... a 'glitch'.

Still, a 'glitch' that clearly demonstrates that your messages are being stored somewhere, by someone.

If these messages were attempted responses to 'valentines day messages', I can imagine how that might get awkward for some, er, 'less than fidelitous' people. I keenly await the next series of 'Black Mirror'.

That aside, it's certainly worth remembering that you're carrying a fondle-slab brimming with sensors around in your pocket - one which you have very little control over as regards what it 'senses' and where that information ends up.
For example, a couple of years ago, a major security flaw was discovered in iOS and Android devices which was already being exploited...
What it does
The Android version performs similar spying functionality as Pegasus for iOS, including:
Keylogging
Screenshot capture
Live audio capture
Remote control of the malware via SMS
Messaging data exfiltration from common applications including WhatsApp, Skype, Facebook, Twitter, Viber, Kakao
Browser history exfiltration
Email exfiltration from Android’s Native Email client
Contacts and text message
It self-destructs if the software feels its position is at risk. Pegasus for Android will remove itself from the phone if:
The SIM MCC ID is invalid
An “antidote” file exists
It has not been able to check in with the servers after 60 days
It receives a command from the server to remove itself
It’s clear that this malware was built to be stealthy, targeted, and is very sophisticated.

Facebook apparently acting to protect our privacy.
Yep, Charlie Brooker's going to be busy.
