I bought D5600 about 7 months ago from nikon store in lulu. And it worked perfect until 4 months after I bought. But after that when I select options such as white balance, iso adjusting display shows some other functions and open automated other options.and same complaint in bluetooth function, it take almost 5 or 7 minutes pair a device and after pairing when I try to send photo then it shows not paired with any modules .
In between these 7 Months I reached 5 times for repairing these type complaints.
