Hello guys I just bought a 930 and after 1 week if use I noticed white artifacts some times when on white screens or giterings .Has anyone else noticed this is it normal ?

This device has AMOLED screen which could get a burning-in and some other shiat with long time screen on (especially on bright backgrounds).
post a picture (not screenshot) with other camera of what you see on white bg (also on bright gray background could see also)

As soon I see it again .The problem is more often on the YouTube app metrotybe and I also notice that the white texts change a little when I scrol down or up is it also the fault of the amoled screen ?
