Chinese telecommunications manufacturer ZTE has announced a flagship Android smartphone with a 4.3-inch display screen.

The ZTE Skate uses the Android 2.3 operating system with an 800MHz processor. It also includes a 5-megapixel Bluetooth, A-GPS, hardware compass, and G-sensor.

LG announced two 3D-capable devices at Mobile World Congress this morning. The LG Optimus 3D, which can record and play 3D video, was widely expected – although the appearance of a tablet with similar 3D cameras was more of a surprise.

Both devices are equipped with twin 5-megapixel cameras on the back… and both have dual-core processors inside.

James Rosewell and Mark Bridge from The Fonecast are in Barcelona this week to report on the events at Mobile World Congress.

The show opens today – but already there have been some major product announcements. Last night, Samsung and Sony Ericsson both revealed some significant new products, while Nokia talked about its partnership with Microsoft. There was also a showcase of new technology at ShowStoppers.

Samsung launched its Galaxy S II smartphone in Barcelona on Sunday night, just a few hours before the official opening of Mobile World Congress.

It’ll be equipped with a Dual Core Processor and a 4.3-inch super AMOLED screen, yet will be less than 8.5mm deep. An 8 megapixel camera and full 1080p HD recording help to complete the spec.

Mark Bridge writes:

“Hot products. Cool companies. Meet the press.”

That was the tagline for ShowStoppers, a showcase event that took place last night before today’s opening of Mobile World Congress. As you probably heard in today’s podcast, I went along and met a few of the participants.
