Hi @Obsydian Sorry to hear this. No spam recently though I did have the odd one a while ago.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
My Device- S21 Ultra 5G ( SM-998B/DS ) CSC= BTU , 12GB/256GB
One Ui 5.0,Android 13 .
*touches wood* Closest thing to spam I've got in my inbox recently was a mass message about an event in Riga sent (presumably in error) by one of our Latvian/Lithuanian colleagues.
Intrigued to know more about the messages you're receiving though, so feel to PM/DM me more info and screenshots.
