The official shipping was supposed to start in this quarter. Well, right now Samsung has made it official and they are rolling out the update to the unlocked S6 devices across the world and next in line are the carrier models.
The Korean tech giant has also revealed the featured packed in this update. The standard features like power-saving Doze option, the micro permission management, or the video sound speed adjustment will be there. In addition to these, Samsung has modified the user interface too. The notification bar region, which is one of the ugly looking feature of TouchWiz, will now sport a white theme.
