Almost every text message I sent sends duplicate text messages. It's very annoying!
I also have issues where I don't receive group messages and can't send picture messages to certain people.
Overall very frustrating. Had these types of problems with my Samsung Note 9 too!
Solved! Go to Solution.
It was suggested by someone to shut off advanced messaging if you have it on. That seemed to work for mine. I think maybe the last update we had, has a glitch. Hopefully they fix it soon.
do you have AT&T? You would need to contact the carrier, I'm sure they know why it's sending duplicate messages, but text messaging issues would be carrier one not Samsung issue.
