It also adds a higher-resolution rear camera (50 MP versus 32 MP), a higher-resolution front camera (20 MP versus 5 MP), optical image stabilization on the main camera, and 100W charging. Oppo A5x, however, is around $396 cheaper, lighter at 193 g versus 234.5 g, and thinner at 7.99 mm versus 8.65 mm.
