After the massive recall of the Samsung Galaxy Note 7 due to reports of exploding batteries, replacement units have been released. However, it seems that these new "safe" ones are still prone to overheating.

Customers in the U.S., China and South Korea who have picked up the "safe" Galaxy Note 7 replacements are reporting that their new devices are overheating, USA Today reported. While it should be expected that no more batteries are exploding this time, these users are now worried that the same might happen again.

Galaxy Note 7 Overheating is not a Safety Concern

Amidst these reports, Samsung assured consumers that the Galaxy Note 7 may feel hot from time to time and that is normal, but it should not explode.

"We would like to reassure everyone that new Note 7 phones are operating properly and pose no safety concerns," Samsung said in a statement. "In normal conditions, all smartphones may experience temperature fluctuations."

According to GSMArena, the South Korean tech company also revealed that they are looking into each complaint separately. They are now trying to resolve these issues via customer service and their warranty.

Galaxy Note 7 Back on the Shelves

Meanwhile, Samsung has just put their Galaxy Note 7 back on the shelves of their home country, South Korea. They have started advertising again after one month of suspension due to their defective batteries that blew up the device while it was charged.

They previously promised that they will relaunch their latest flagship phablet on Oct. 1 with pre-orders starting Sept. 26. Although the controversy led to injuries, damaged properties and lawsuits, it seems that the consumers are still interested in the Note 7.

The tech giant received 16,000 orders within the first day of pre-order and is expecting 20,000 more today.

The Galaxy Note 7 is also set to formally launch in Europe by the end of October.
