LG Uplus has released a water-resistant, long-term evolution (LTE) smartphone, the company said on Monday.

The G'zOne, developed by Casio, a Japanese electronics firm, is the first waterproof LTE device in Korea and will not be damaged in water up to 1.5 meters deep for a maximum of 30 minutes.

"As the earphone and charger ports are well covered, the smartphone won’t break even if it is dropped in water," said an LG Uplus spokesman.

Models show LG's new water-resistant smartphones at a swimming pool in Seoul on Monday.

The G'zOne is waterproof to the IPX8 standard, the highest rating, and also passed tests for collision-induced absorption on par with U.S. military standards, making it perfect for outdoor leisure activities, the mobile carrier said.

The handset is also equipped with bumpers for shock resistance on its sides and back and has tempered glass on the front that will not break if dropped.

It has a four-inch screen and runs the Android 4.0 operating system. The handset is priced at W423,500 (US$1=W1,115).
