[Message] Increasing coherence when using dualSIM
There's an option under SETTINGS > NETWORK&INTERNET > SIM CARDS > clicking on '1' or '2' > COLOUR, where a different colour scheme for theeach of the SIM cards can be chosen optionally. As a consequence, when the phone is ringing, the background color of the phone app is being adapted to those chosen colours.
Upon usage of the MESSAGE SMS app, while composing a message the sender phone number can be changed (see below, image 2) by clicking on the little SIM card number ('1' or '2').
It would be coherent if that little number would be coloured according to the color schemes chosen above.
