Users of older models will see a warning every time they charge or turn on their phone.
Samsung said Tuesday that it is working with U.S. carriers on a software update that will allow Galaxy Note 7 owners to easily see if their phone is one that has been recalled or one with a newer battery unaffected by the recall.
Those still using an older model will see a warning to let them know their phone has been recalled, urging them to power down and exchange the device. That warning will show up each time a user powers on or charges the device.
The update will show a green battery icon to those with a new model, indicating a phone unaffected by the recall.
Samsung stopped selling the Galaxy Note 7 on Sept. 2, but didn’t formally recall it in the U.S. until last week. As of then, fewer than 15 percent of the more than one million phones sold had been exchanged or returned.
