MWC 2012: Samsung overview
Samsung Galaxy Beam hands-on
The Samsung Galaxy Beam is the thinnest portable projector phone, Samsung claim, and they just might be right - it's 12.5mm thick at its slimmest point and bulges where the projector is. It's a bit chunky.
The optimal distance for the projector is 2 meters and in a dark room the quality is actually pretty good. The beamed image has nHD resolution (640x360). The Galaxy Beam is expected to have 3 hours of battery backup in projection mode.
There are a couple of features that weren't working in the demo unit - you'll be able to focus the projector lens with an app (currently, this is done with the volume rocker and isn't very user-friendly) and the projected image will be autorotated just like the screen.
