Asus’ re-entry to the smartphone market (after a failed partnership with Garmin) is highlighted by their flagship Android handset called the Asus Padfone, an ICS smartphone that transforms into a tablet.

First unveiled in Computex back in May 2011, the Asus Padfone is a combination of a tablet that’s powered by a detachable Android phone.

Asus didn’t have full specifications of the Padfone then.

While Sony has already announced its first flagship smartphone (post-Sony Ericsson era) with the Xperia S, two new mid-level handsets were also revealed — the Xperia P and the Xperia U.

Nokia earlier teased us with the super-cameraphone and has finally announced theNokia 808 PureView with a humongous 41-megapixel camera.

Running on a Symbian Belle OS, the Nokia 808 basically replaces the Nokia N8 as company’s flagship cameraphone.

Samsung is introducing yet another model in the 10.1-inch category of its Galaxy Tab line-up, the Galaxy Tab 2 10.1. What is rather odd is that the design and hardware specifications of the Galaxy Tab 2 10.1 is almost the same as the older tablet, except for the fact that the new one comes with Android 4.0 ICS out of the box.

Samsung also announced a Galaxy Tab 2 7.0 last February 13 so this Tab 2 10.1 is just part of that new batch.

LG Mobile has officially unveiled the successor to the Optimus 2X. Touting a quad-core, Tegra 3 processor running on Android Ice Cream Sandwich, the LG Optimus 4X HD is one of the first Tegra 3 handsets in the world.

LG scored points when it announced the first dual-core smartphone last year and wants repeat that record with the first quad-core smartphone this year.
