Like the Verizon version yesterday, T-Mobile and AT&T models of the Galaxy Note 7 are receiving their battery indicator change update. In this update, the battery indicator will turn to green (from white) to let you know that the Note 7 in your hand is safe and should be free from exploding.
If you are still holding onto the bomb-ready version of the Note 7, this update will add warnings all over the place in an attempt to get you to exchange. You should exchange it. Also, for additional details on how you can tell if your Note 7 is safe or not, hit up this post.
The T-Mobile update will arrive as software version UVU2API4 and the AT&T update will be UCS2APHE.
