Samsung has begun replacing the Galaxy Note7 with a battery manufacturing standard. To help users easily understand if they have a new device and  use their new Galaxy Note7 with confidence, the company has introduced a Green battery icon that has been included in three specific software changes.
 
The new green battery icon will be visible on: 1) the Status Bar; 2) the Always On Display screen; and 3) the Power Off prompt screen, which can be accessed by long-pressing the power key.

Additionally, users can easily check if they are using the new Galaxy Note7 by looking for a square symbol on the label of the packaging box as below.

Our highest priority is the safety of our customers, and we strongly urge Galaxy Note7 users to immediately participate in the replacement program based on local availability.
