You click a photo and when you open the pic for the very first time, you get a lag barely a second but its noticable. For every other time you open a photograph its perfectly fine. I haven't observed this in any other smartphone.
You don't have an option of turning your phone to full screen mode i.e. with a visible notch, specifically to user selected apps.
Face detection is not working properly after the update. Fingerprint sensor is working pretty awesome.
Otherwise the NOKIA 6.1 PLUS is an awesome phone for use. I am very happy and satisfied to buy NOKIA after around a decade. It seems the big boss is back from Finland.
