The disastrous story of the Samsung Galaxy Note 7 continues, with a report from The Verge confirming that just 130,000 units have been returned to Samsung since the company notified the public of the explosive battery issue.

According to the US Consumer Product Safety Commission, around one million Galaxy Note 7s are affected by the official recall that was announced yesterday. If only 130,000 people returned their device during Samsung's voluntary exchange period, this would indicate almost 90 percent of the Galaxy Note 7s in the wild have not been replaced and could still pose a safety threat to their owners.

There are several potential reasons why users are not returning their Note 7s despite the recall. Samsung hasn't provided significant quantities of replacement Note 7s just yet, so some users are being offered different (and much worse) devices that they don't want. The information Samsung has published about the recall has often been confusing and lacking in detail as well, which makes it difficult to know the exact exchange process.

However, Samsung has improved their information about the recall over the past week. The company now has a date after which replacement devices will be available at retail stores (September 21st), and various notices will be published through Samsung's marketing channels to encourage users to swap their hazardous smartphones.

There have been a few reports suggesting Samsung will make it easy to identify which phones contain safe batteries through different packaging and changes to the software, however owners will still have issues convincing some companies – airlines in particular – that their replaced variant won't explode.
