South Korea's LG Electronics released a dual-screen 5g smartphone on Sunday, the latest design feature to revive flagging sales.
The two screens on the new V50ThinQ work independently, so users can watch movies on one screen while browsing the internet on the other.

Smartphone maker sales fell for a quarter last year as Chinese rivals Huawei technology and Xiaomi seized market share in a slightly weaker global market.
On the eve of the Mobile World Congress, both companies announced 5g mobile phones in Barcelona, the main annual gathering in the telecom industry, and Xiaomi launched a $680 model, huawei broke the price limit with a $2,600 folding phone.
Still, LG retains followers of those who value good video and audio quality.
For these users, LG launched the second mobile phone G8ThinQ, which can be unlocked without touching the screen.

LG product evangelist David Montania said at the press conference that "cheating" is more difficult than the FaceID feature used in Apple's iPhone X, because the vein structure in the user's hand is in the same billion as others.
Users can also activate the function through gestures-
