A new leak appeared this week, showing off a Microsoft branded casing for a phablet sized device. The general consensus is that this is the Lumia 1320’s successor, the Lumia 1330, the casing shows off a raised camera housing (similar to the Lumia 1520), along with a tiny slot for an LED flash. The general LED and camera placement are quite similar to the 1320, however in this casing the speaker port has migrated from the lower right of the phone to the right side of the camera.
As of now we don’t have any solid specs to go off of, but given the comparison against the Lumia 535, we can assume it’s a 6″ device (give or take), with a user removable back cover. It’s likely we’ll see this device unveiled at MWC this year, which is only a few months away.
