The Galaxy Note 7 launched with plenty of fanfare, but was quickly marred by a growing number of complaints regarding faulty batteries causing devices to explode.

That ultimately led Samsung to issue a recall, and begin to either exchange units for customers, or provide a means for an easy way to return the device and go with something else entirely. Since then, Samsung has been working on launching new Galaxy Note 7 units with a replaced battery inside. Samsung also made it clear that the devices feature ways to change if the battery has been replaced with a new, presumably safe unit inside.

However, now that the replacement units are starting to trickle out into the real world and customers are getting their hands on them, some issues are apparently arising. Customers in South Korea, where replacement units first arrived, are reportedly suffering from Galaxy Note 7 units that won’t charge, suffer a sudden loss of power while charging, and still overheating while charging as well.

As of right now, it appears the issue is only plaguing owners in the South Korea, but Samsung has not commented on whether or not the issue is being discovered in other territories. Samsung was not able to confirm the number of current complaints with these latest issues, either.

A Samsung spokesperson did tell The Wall Street Journal that these current issues are “completely unrelated to batteries,” for what it’s worth.

Have you had any issues with your Galaxy Note 7? Did you get a replacement?
