Your English is fine. Your problem is an odd one.

Make sure the phone is fully charged and see if the behavior is the same. Maybe it's going to a low-power battery saver state?

If you haven't downloaded any screen brightness management app, I think you might want to perform a Factory Data Reset. If that doesn't clear the issue, then it might be necessary to get a replacement.
