Samsung has already hinted that there will be easy ways to determine whether or not the Galaxy Note 7 you have in your hand has a safe battery, but it's not leaving anything to chance. The company has posted a guide that shows you exactly what to look for if you're worried that someone gave you a dud. That green battery icon Samsung mentioned before? It'll be everywhere, whether it's in the status bar, the always-on display mode or the power-off screen. You can also look for a square symbol on the box label. These visual cues will likely be unnecessary before long, but it's good to have them in case someone tries to sell you one of the fire-prone models.
