LG Electronics on Wednesday released another teaser for its upcoming flagship G5 smartphone, providing a glimpse of its design and features. In a brief video, the G5 smartphone is said to be "Always ON" and appears to "never go asleep while others do."

The "Always ON" feature was first introduced through the V10 smartphone last year, which came with a dual display, with the smaller one on top displaying core information, such as battery status on a 24-hour basis.

LG Electronics may have adopted the "Always ON" screen in the center of the display for better readability, compared with the V10 smartphone.

Earlier this month, LG Electronics sent out three invitations that read, "Come meet new friends on the playground," featuring balloon animals, toy robots and air dancers.

The G5 smartphone will be introduced on Feb. 21, a day before the opening of the Mobile World Congress in Barcelona, Spain. On the same day, Samsung Electronics will showcase its Galaxy S7 in Barcelona.

LG is rumored to be adopting a metal body for the G5 to improve design. According to Android Authority's sources, the flagship phone won't have an AMOLED display and will instead have a full screen version of the LG V10's second, smaller screen.
