hp prime flickering when scrolling

[ioupeka]

Hello everybody,

I'me very new in the hp calculator familly and did just buy an hp prime form my exam's un march. Also please excuse my approximate englisch.

I noticed, when scrolling down that my hp prime does some kind of flickering. See this video: https://photos.app.goo.gl/YTFFBsKhJfWqyNDH3

Can anyone tell me if this is normal, also on yours, or if my calculator has a problem ? I tried to get in touch with the hp support with this question, but i my contry it seems impossible to reach them, all I can do is send the calculator back.

Thanks in advance,
