Samsung launched a new Galaxy S smartphone called "Continuum," with a secondary 1.8-inch "ticker" almost-always-on touch panel mounted beneath the Continuum's 3.7" Super AMOLED screen. The ticker screen can be used to show RSS updates, incoming and missed messages, be used to launch widgets, or control calling and media player functions while the main screen is turned off.
Firstly, using ticker screen for essential information like messaging and feeds, you don't have to activate larger screen, and less battery power is consumed. The same goes for occasions when the media player or call controls are minimized to ticker window, it actually improves usability of these functions.
It means Samsung has a live Android 2.1 branch that supports multiple touchscreens. Among other things, this could be used to build an Android smartphone in new form factors, like clamshell, which doesn't exist in the Android world yet.
Samsung's Galaxy S line of mobile devices casts a broad shadow over the increasingly crowded Android business, with its Super AMOLED-equipped 1GHz devices on top five wireless carriers in the US, and 7" Galaxy Tab available with carrier subsidies, or as a no-contract, Wi-Fi only device. Though a Samsung representative tonight said it's actually just the standard 4" touch panel "broken into three sections."
