1. Is it possible to add favourite caller list in MIUI like samsung galaxy series? In galaxy series, frequent caller no will be auto added to favorite, save the hassle to search the contact. The recent list will kept the most recent call at top, so the list kept pushing down, not as user friendly as favorite list.

2. Is there a way to send sms or whatsapp to the contact name in recent list? used to be able to do this in galaxy series too, miss that convenience.

Well, when you have parents staying away from you, and they miss their grand children but couldn't come to your house or you hardly got time to visit them, you will know how great is to have a video call function.
In android, only Samsung phone has it iinm.
