LG Electronics' new flagship smartphone, the G6, will be safer and handle internal heat more effectively, the company said Sunday.

LG plans to unveil the G6 at the Mobile World Congress (MWC) 2017 in Barcelona next month. The announcement can be seen as a move to highlight the handset's safety after the fiasco of Samsung Electronics' Galaxy Note 7, which was pulled from global markets last year due to a critical fire problem.

"As more consumers prefer safer smartphones, we will raise the level of safety and quality standards for our next strategic smartphone," said Lee Suk-jong, head of LG Electronics' mobile communications global operations group.

LG Electronics said it is improving efficiency of the smartphone's heat emission to prevent battery heating from causing safety problems. To this end, it has adopted copper heat pipes that have high thermal conductivity. The pipes are widely used to cool laptops and desktop computers and will be able to reduce the heat given off by the mobile application processor of smartphones by up to 10 percent. LG Electronics also said it has redesigned the new smartphone to give more space between components to disperse heat.

The company said it has applied 15 percent higher standards in battery heat exposure tests compared with those of the IEE1725 standard in the United States and the IEC62.133 in Europe. Anti-puncture and anti-shock tests also will be conducted, it said.

For use in even tougher environments, the company will introduce a test to see if a handset's application processor, display, camera and fingerprint sensor can survive extreme temperatures, humidity, shock and external damage.

The company said the V20, which was released after the G5 last year, also acquired the MIL-STD 810G product durability certificate from the U.S. Department of Defense.
