The K900 phablet (http://www.gsmarena.com/lenovo_k900_55_1080p_screen_13mp_camera_and_dualcore_atom-news-5319.php) might be hogging the spotlight, but Lenovo has four more Android handsets to show at CES. Details are a bit scarce, but they are all dual-SIM devices and range from an entry-level Gingerbread droid to a 5" Jelly Bean upper mid-ranger.
That upper mid-ranger would be the Lenovo IdeaPhone S890 - it has a 5" qHD (540 x 960) screen with 220ppi pixel density and runs Android 4.2 Jelly Bean. It packs an 8MP camera with flash inside a 9.3mm thick body that weighs 176g.
The IdeaPhone S720 has a smaller 4.5" IPS LCD screen of qHD resolution (245ppi). The phone runs Android 4.0 Ice Cream Sandwich, powered by a dual-core MTK processor. There's an 8MP camera on the back and a 1MP snapper at the front. The S720 has a 2000mAh battery and is 9.9mm thick.
