My Galaxy S7 camera is very bad, is it refurbished or clone ?

I bought a galaxy s7 from a local shop without any sort of warranty , i checked with iemi ,benchmark app,everything seems ok
but my camera images are very bad quality, cant zoom a little,picture gets blurred,also objects in the image are also discolored/over colored, can anyone post their indoor,low light,daylight ORIGINAL resolution photos ? so that i can check or test mine ? :( :( :(
