Before updating I've always had a choice of choosing which card I want to use for calling or sending messages, those options were always visible on screen. Now after updating for calls i get pop up windows asking for SIM while in messages I have no options at all. Does anyone using two SIM cards have the same problem?
I am terribly sorry to break the news but if you read the thread mentioned by @DualSIMNote10Plus you will notice that it is entirely unrelated to the issue discussed here. I have tried to point this out, but @DualSIMNote10Plus seems to not have read or understood.
That being said, at least on the S20 we have been talking about in the above-mentioned thread, there is a SIM selection button in both the phone and messages app.
You can see it in the screenshots below. It is the button that says "Telekom". If you touch it, a dialog opens that lets you choose another sim.
Important: If you want to change the SIM for existing threads in the messages app, an extra step is required: First, you need to tap the three dot menu in the top right of the active thread. The SIM selection button can then be found at the lower end of the menu:
@AemJay - I did NOT misunderstand anything.....you clearly need to READ AGAIN!! And stop posting fake news when this major issue has not been resolved!!
Also, NO ONE CARES about the instructions you are sharing on switching SIM......PLEASE STOP promoting this non sense!
When you say "reverted back to default UI" you mean @DualSimNote10Plus went back to an older version of the firmware... the older version that has both the sim buttons?
@DieLyn - please read my recommendations on PAGE 12 of this thread, clearly shows detailed instructions on how to bring back both SIM1 and SIM2 buttons for calls and messages by reverting back to Android 10, UI 2.5.
This is a recommended TEMP SOLUTION meanwhile, unfortunately, the Samasung Community Moderators ie. @Antz are not helping with this major issue....they rather continue to ignore our important, urgent and high priority request impacting ALL loyal Samsung Dual SIM users worldwide. Unfortunately it is not a perfect worldwide, so there are a few abnormal folks ie. @ElfStone that distract Samsung requesting not to fix this major issue. We have requested Samsung Community Moderators to help escalate this and directly bring to the attention of Samsung senior ranking executives but unfortunately they refuse to fulfill their responsibilities as Samsung employees. The Moderarors here provide ZERO value and continue their bad behavior supporting @ElfStone .
