@juicylala926 you'll need to go into your messaging application type out your text then tap the plus sign. If the Gallery comes up tap the three dots on the right side of the menu and it should bring up more options and allow you to schedule a message.
@cosmic Ray .You are awesome! I had a stroke a year ago and i got so use to utilizing scheduling messaging. So thankful for people like you that will take out the time to share with us when Samsung wouldnt. God bless yo
