Lost dual SIM choice in calls and messages after update to UI3. Anyone knows how to bring them back?

[Gorog]

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?

@Lilian c , @Gorog , All - this is resolved ! Did y'All not see my earlier post? I have provided instructions on how to get but SIM1 and SIM2 buttons back for both phone calls and SMS. Surprised people still having issues....

Hello AndroidKing,

What was your solution? Rollback the OS version?

@DieLyn , please reference the solution I had already posted in this thread. Not sure what page it is on....

Hello there, so.. I posted here black in 2021 when Samsung decided to make this nonsense update. After that, I started using the True Phone Dialer & Contacts app that manages dual sim beautifully and has a lot of costumization. 

If any of you would like to try it, I recommend!
