According to Liliputing, Samsung set to unveil a new hybrid device this fall, at the IFA trade show in Berlin, Germany in September.
This mysterious device (aka Galaxy Q) rumored to have a 5.3-inch display, situated somewhere between the Galaxy S line and Galaxy Tab. It seems this will be a tablet with phone capabilities, though I don’t think it will fit in our pockets that well, but we will be able to play games and watch videos.
Among Samsung smartphones Infuse 4G has the biggest display (4.5-inch) and Galaxy Tab the 7-inch tablet is the smallest out on sale now.
