I bought oppo n1 in august 2015 . when I bought every friend whom I mate they saw my phone they liked the phone . but in oppo n1 mobile camera is amazing compare to other by that time it is really good capturing imagae. after five to six month suddenly my phone got hanged so I did format and restart than my camera and all function r working properly but I got one new problem when I do video recording my flash not working . just flash work with image taking but not working for video recording . I told many times to mobile shop owner he is not giving any response to me. but I think oppo n1 is good phone just one mistake I had so I m giving u idea before buying phone plz ask salesman that if it get any problem will u give a good service to me bht phone is overall good for everyone.
