Weird text at bottom of screen

[USER_4390DV]

Hi everyone, this just started today. These texts from random numbers show up at the BOTTOM of my screen. I thought it was an update or something but when I get texts from my mom or someone in my contacts, it shows up at the top and in the notification bar. And these either say "save" or "cancel" is anyone having the same problem? I hope it's not malware or something

I'm thinking it's spam/phishing text that is being currently blocked?
