 Question: 
After ending a call using SIM2, the call back screen is assigned to only 
SIM1 which is designated as default SIM 
  
Answer: 
According to the preferred SIM concept, users mainly make a call with preferred 
SIM.  
So the UI of R OS has been changed to only make a call with the corresponding 
SIM on Recents and Keypad of Dialer.
