The battle for the world’s thinnest (Android) smart phone rages on today with word of the NEC MEDIAS. Ranging between 7.7mm at its thinnest and 8.7mm at the thickest, it easily takes the title from devices such as the Xperia Arc and last week’s Samsung Galaxy S II. Other details for the handset include an 800MHz processor, 512MB RAM, a 4-inch screen, and a 5-megapixel camera. According to reports, this phone will be announced later this week for NTT DoCoMo. While it may not see the level of promotion or release, the MEDIAS can hold its head up high for the time being.
