It is highly desirable Samsung can implement a change that can backup/restore RCS messages.
Transfer message from Samsung mobile to Samsung mobile turns all RCS messages into SMS or MMS. It makes the user experience bad by using RCS app. That is to say, all high-quality photos or videos are downgraded to very poor quality, which means that the photo memories you have all those years in the RCS message app do not look so good after messages transfer to other Samsung mobile.
All RCS messages are converted to SMS or MMS, it is completely unrespectable why RCS messages are converted to SMS or MMS. It make zero sense to use RCS when all messages will one day turn in to SMS or MMS. It is rather (perhaps) better to use SMS or MMS when you know that once the user change(s) smartphone(s) or restores messages, will all messages converted into SMS/MMS.
So please fix it.
It's a completely different topic, but implicit changes also to Wear OS.
Better synchronization between the Samsung mobile and the watch for messages
Very often it is shown on the watch about messages are unread (if the user has unread messages (10, 20, 100) will user receive all messages and notifications again ONLY on the watch.
When the watch is not connected to the smartphone for a while or the user leaves the smartphone behind and only have the watch. It is not a good experience when the user himself has to read all messages on the watch again.
But the watch assumes that messages have been read for now when the smartphone and the watch are connected, but when the mobile and the watch are not connected together the watch will assume that all new messages are unread (The user is kind of messages spammed in a certain way with unread messages on the watch).
It is bad user experience and user has to downloading pictures and video self. It is not a good enough solution.
At the same time, what is the point of using RCS, when messages are converted to SMS/MMS.
Quite simply, RCS must improve.
