Samsung has made great efforts to make the Galaxy Note 7 global recall as painless and quick as possible. Earlier today they released information about the replacement Note 7 stock in Australia, revealing that (at least in the land down under) replacement stock will be available September 21. But the second part of the announcement is noteworthy - Samsung has a plan to identify safe Note 7 devices from the original batch.
Replacement Note 7 phones will have a different IMEI from the original phones. This makes it much easier to tell if your Note 7 is affected or not, and with IEMI identifiers being effectively unchangeable, it's practically full-proof. For example, if you're buying a used Note 7, it won't take long to tell if you're buying a dud.
Samsung reports that users will be able to check their IMEI numbers through an online database starting September 13. In addition to the IMEI identifier, new Galaxy Note 7 packaging will include a small black square next to the barcode sticker, as seen here:
With Samsung making it easy to tell if you ever purchase an affected Note 7, and handling the recall as smoothly as can be expected, I have to give the company credit. Keep in mind all of this information comes from Samsung's Australia site, so this information could be subject to change for other regions.
