Flyme OS 6.7.3.28 beta (m3 note)

@Rey my brightness is not working, it is totally deam even in adjust it in normal or in autobrightness. When I activate the inbuilt screen recorder its works as normal. This happen yesterday night. But I thought that if I download this update so that it may fix but it is as it is. Please help me. What would I do. Is it software or hardware problem.
