Sigh. Some Samsung Note7 replacements have overheating and battery drain issues

Samsung's Galaxy Note7 nightmare just won't end.

After an official recall of its Note7 phone with the U.S. Consumer Product Safety Commission (CPSC) and the banning of the faulty devices on flights by the Federal Aviation Administration, Samsung finally started shipping loads and loads of replacement devices for Note7 owners to exchange.

As of Friday, Samsung Electronics America said about half of the 1 million recalled devices in the U.S. have been exchanged.

Safe Note7 phones have a green battery icon in two places: on the lock screen and at the top of the home screen.

All good, right? Samsung identified battery defects as the cause of the exploding phones and is replacing them. People are exchanging them and all will soon be forgotten, right?

Not quite.

Maybe things are OK in the U.S., but overseas in South Korea, consumers are seeing new issues with their replacement devices.

South Korean news network YTN reported that some Note7 replacements are suffering from overheating and fast battery discharge, according to the Wall Street Journal.

The issues are reportedly unrelated to the battery defects that prompted the global recall.

The reported issues for the replacement Note7 devices are "completely unrelated to batteries" and are "isolated cases" caused by mass production, a Samsung spokesperson told the WSJ.

Mashable has reached out to Samsung Electronics America for comment on whether it received any similar reports about replacement Note7 phones.

Let's face it: The Note7 is Samsung's biggest blunder. The phone itself is solid -- Android's best -- but quality control issues have ruined it.

According to Bloomberg, Samsung may have rushed the Note7 in order to beat Apple's "boring" iPhone 7 phones. With all the manufacturing problems, the story certainly matches up.

But at this point, it's worth asking: Why even bother with the Note7? The phone's launch and relaunch is shaping up to be a disaster (even if the new problems are unrelated to the first ones).

I certainly wouldn't bother with all the hassle. Imagine getting a Note7, exchanging it for a new one only for it to have its own set of problems? It's the worst thing that could happen.

Samsung better pray the new reports and defects really are limited to a very small batch of replacement phones, or the company will have even bigger problems to worry about later.

The company's reputation is now riding on the Note7's successful recall, even if the sales for the phone never recover.

Samsung customers have literally been burned. It's truly unfortunate the Note7 has turned into such a bust, and the company needs to take the necessary steps to reassure consumers that its phones are indeed safe and problem-free. Otherwise, it risks losing whoever's left for the S8 or Note8 next year.
