Hi,
First of all welcome everyone as it's my first port on the forum : )
I wonder, if there is a way of adding a tag/marking on the call history list so there is a clear indication of what SIM was used for particular call on the list.
I had this feature on Samsung branded Android and found it very useful.
I know this can be checked by choosing particular call and going in to the call info, but this way is quite user-unfriendly.
