New Samsung phone, SM-G150N, appears in various places; this could be the Samsung Galaxy Young 3
Considering that the Samsung Galaxy Young 2 was the SM-G130, it would make perfect sense for the SM-G150 to be the Samsung Galaxy Young 3. The Galaxy Young 2 was released this past October, over seven months ago.
Don't expect too much from this model. After all, the Galaxy Young 2 features a 3.5-inch screen with a resolution of 320 x 480. A single-core 1GHz CPU is under the hood and there is 512MB of RAM inside. The Galaxy Young 3 will probably carry similar specs with a slightly larger screen-size, a slight bump in resolution, and a higher MP camera.
