One of these areas is the building material, as can be seen in the photos. The S21 FE does not have a premium finish and instead appears to use plastic.
While the camera island looks like the camera bumps on the Galaxy S21 and S21 Plus, the phone is unlikely to inherit their setup and instead will come with a 32 MP main sensor, one unit. 12 MP ultra-wide and 8 MP telephoto lens.
The screen will apparently be 6.4 inches and the phone is expected to pack a 4,500mAh battery. Other leaked specs include an in-display fingerprint reader, 120Hz refresh rate, Dolby Atmos support, and IP68 dust and water resistance.
