I have had the problem for several weeks but when I dictate punctuation words, nothing is typed - not the punctuation nor the actual word such as "period". By accident, I discovered that is DOES work if I have data or wifi on, but not if they are off. The rest of voice to texting is fine with data off, just the punctuation words not working.
Yesterday I did an online chat with Samsung support and she had me delete the cache in the samsung keyboard with no effect. Also had me start up in safe mode and the problem persisted. Her final suggestion was a factory reset, which I declined - not wanting to wipe out years of stuff.
The Samsung tech said they have no record of any reports of this problem??? I linked her to this thread to which she replied that it is a 3rd party site and not a Samsung site - so it doesn't count I guess. So
PLEASE EVERYONE HERE FILE A REPORT WITH SAMSUNG so they are aware:
