The Oppo Find 7s is very similar to the Find 7a smartphone, but it comes with one major difference: the QHD display. Yes, the original Oppo Find 7a comes with the FhD (Full HD) display while the Find 7s comes with a QHD (Quad HD) display. The Quad HD is a notch with up its competition. In addition to the display, Oppo are giving this one a premium metal frame. Just because something is metal doesn’t necessarily mean it is better,. However, some devices like the Samsung range are continually ‘copping flak’ over having a finish that doesn’t feel expensive. Others argue that they prefer plastic for its practicality.
