It feels like yesterday we were discussing the alleged death of form factor diversity in the smartphone world, and now Samsung comes up with this: a mid-range clamshell called the Galaxy Folder (SHV-E400K) with displays on both sides of the lid. According to Japanese site RBMen, which discovered a Korean-language user manual for the device on Samsung's website, at least one of the displays is a 3.7-inch AMOLED panel with 800 x 480 resolution. Other specs include a Snapdragon 400 dual-core chip, 2GB of RAM and LTE support. The basic design is nothing new to Samsung, which came out with the similar SCH-W2013 in China last year, and the SCH-W999 a year before that, but it's good to see evidence of its survival in 2013 -- and especially if it's destined for Samsung's home market. If it was up to us though, we'd put some e-ink in that second display.
