If you are still under store return period, please do yourself a favor and return it . D3200 had this similar problem and tried all the tricks and nothing helped even switching the lens. So frustrated with this I went and got a Canon EOS Rebel T6 DSLR premium kit with a EF5 18=55mm and EF 75 - 300 mm lens and Canon camera bag for less than half the price what I had paid for the Nikon camera and base lens only. I am more than happy now. The pictures are lazer sharp and very vibrant color.
