Oppo f 1s which comes with a cam of rear 13mp & front 16mp.back camera is not up to the mark as we zoom the pic it break where as front is considered it comes wth 16 which is good upto some extent.but no so clear pis.where as its platfom its runs on andriod 5.0 which is not at all good it lacks in the perfomance as phone hangs sevral times while we use multiple windows.as far as batrrery considered 3075mah its ok.but as per the perfomance with other mobiles its not up to the mark.and 16k is too much for this phone.
