hello, i have an android and i opened up my contacts to call someone and under the new contacts section were two contacts that i have absolutely no recollection of. one was "Spitler" and the other was "Dude". there's absolutely no call or message history with them. if you click to message Dude, it goes straight to message Spitler. the area code is in another state, tried looking up the number online, no luck. i didn't put these numbers in my contacts, how did they get there? my contacts list is very short because i mainly message people through messaging apps and such, i'd remember putting those contacts in because i only have family and work numbers in my contacts. anyone know how they got there by any chance? should i be worried about this?
