Prior to issuing a software update in December that disabled Note 7 units from charging, Samsung had received around 85% of the recalled devices. It looks like the rather draconian measure proved a successful decision, as the return rate climbed to 96% in the weeks after.
Samsung is expected to release the results of its investigation into the Galaxy Note 7 this month. The company is still expected to continue the Note series by releasing a successor to the Note 7 in the second half of 2017.
The fate of the remaining 4% of Note 7 devices isn't clear. Hopefully, we won't be hearing about random accidents caused by stray units in the months or years ahead.
