Oppo f1 has robust configuration, excellent font camera, metal body, large storage capacity, 2500 mah battery which is nonremovable in nature, 5inch display with gorilla glass.
Oppo f1 has an 8-megapixel font camera with f/2.0 aperture lens and a sensor size of 1/4 inches. this allows for light to enter the camera. so you can take a clear selfie even in less lighting condition.it has a premium metal body and softer to touch.
With regards to the concepts and ideas I would give 8 marks out of 10 but performance wise it is 6 marks out of 10.
