I bought this mobile LENEVO VIBE C one year ago. its sound quality is very good and also this set is user friendly. its style and design is very nice and comfortable but when we shoot pictures at night with flash then its working very bad, pics are note clear and the camera quality is also not good the back camera is 5 megapixel but it does not shoot any written document. It has another problem about Facebook, fb official app is not working on this phone and when we try to use fb, whats app and other app then its working very slowly and some time its stopped working. Occasionally, all save contact numbers are automatically deleted and it comes back after we restarted the phone. So in the last I want to say that it is not a very good mobile phone for new generation.
