Brightness Randomly Dims On Note 7

I actullly started noticing this same issue after reading a few posts on AC.

I thought I was imagining it to be a little dim but I dis did notice that would change at times.

I read on another thread about keeping the brightness on high ( which I normally do anyways ) but clicking the Auto on which I normally do not do ?!

Since doing this I've seen my screen at its brightness with no slight change to it
