Scheduled messages is a feature that allows scheduling messages to be sent at a later time.
This feature works by locally scheduling the messages to be sent, and then sending them at the designated time. In other words, the device you scheduled the messages on must be online at the time you set in order for the messages to be sent. Otherwise, they will be sent as soon as the device reconnects to the internet.[4][5]
Consequently, in order for the feature to work on Android, the android.permission.SCHEDULE_EXACT_ALARM permission must be, in general, granted to Signal. However, if Signal's battery mode is set to "Unrestricted" in Android settings, the permission is not necessary.[6][7]
You can cancel sending a scheduled message at any time before it gets sent.[8]
As of Signal Android 6.10.2, scheduling a message to be sent to Note to Self will work as normal, however in the future it's planned that there will be a notification when it's sent, i.e. it will work like a "reminder".[2]
The scheduled message takes the chat settings (in particular, disappearing messages) like a "snapshot" when you schedule it and sends the message with these settings, even if they change before the designated time arrives. The same principle applies if you send a location—the location sent will be the one that you chose when you initially scheduled the message.[2]
