Some of them happen to be model numbers that are not unknown quantities, but rather, have figured out in the news before. For instance, the Samsung SM-W350F was talked about earlier this morning, where it was seen in a UAProf on the Samsung website. Many believe that the Samsung SM-W350F will be a new and upcoming Windows Phone 8.1 device that sports a 480 x 800 WVGA display, where a pair of these units were shipped into India, carrying a converted value of $259 each.
As for the Samsung SM-Z9005, this happens to be a Tizen powered handset that has a resolution of 720 x 1280, while the Samsung SM-C115L is widely believed to be a variant of the camera-loving Samsung Galaxy S5 Zoom. Time will reveal what all three of these will deliver.
