Several big Asian phone companies launched new high-end smartphones and other wireless gizmos, hoping to challenge US giant Apple in a big year for wireless gadgets.
Samsung, fellow South Korean firm LG and hip Chinese maker HTC timed their smartphone launches to grab the attention on the eve of the Mobile World Congress, the world's biggest telecoms trade fair, in Barcelona, Spain.
In a head-on challenge to Apple's popular iPhone 6 which was released last year, Samsung came out fighting today with the Galaxy S6, a smartphone with a touchscreen that curves around the edges and has a wireless charger.
It also presented the larger S6 Edge, a "phablet" somewhere between a tablet and a phone in size.
LG unveiled a new top-line phone with a curved back to sit snugly in the palm, the LG Flex 2, as well as a range of four new mid-range smartphones and two new luxury internet-connected watches.
