I bought my Galaxy Note 4 a couple of days ago and just when I was happy with my purchase, I discovered there is no native SIP functionality on it. I have always been an Android user and the native SIP was there on my previous devices. It is strange to see that it has been removed from Galaxy Note 4 (Android 4.4.4). Instead of adding new functionalities a top of the line product has less features than its predecessors. Is there any way I can add in the native SIP on my device?
