I have a huawei p8 light.

I just noticed a bright spot in the handydisplay, which is getting bigger. He comes from the top edge, right of my phone and you see this only if you have a white background.

what could that be? I have no protective film, my cell phone has not fallen down or something. It was just there suddenly.

Take a screenshot so that we can see it better
