Samsung Galaxy F (or Galaxy S5 prime) has been spotted a few different times over the past few months. Its said to have a metal build rather than plastic found on the current flagship. You can see the back has a brushed metal finish.
You can also see in the image above that the Galaxy F has extremely thin bezels rivaling the likes of the LG G3. Its unclear whether with the new build, the Galaxy S5 Prime will have IP67 certification for dust and water resistance or not. Its difficult to make a metallic phone water resistant, but we would know more about that later.
According to previous leaks, the Galaxy F is expected to have a 5.3-inch QHD (1440x2560 pixels) display, powered by the Snapdragon 801 processor with 3 GB RAM and 16 MP camera.
