I use dark modes where possible. If there's very little to display on a screen in dark mode. my display GOES DARKER! If I turn auto brightness on, the screen will go completely black! The same occurs if, for example, I tap on a sample display in the Play Store which is mostly black. So it's delibrately making a hard-to-read screen HARDER! This is independent of what app I'm using. As long as the display is almost all black, it TURNS BRIGHTNESS DOWN! Stupid.

I have same issue but this problem began after Oreo update. Nowadays somekind of dynamic dimming is also pumping screen brightness up and down all the time. It is very annoying especially when watching movies. Before Orea I haven't these problem att all.

How do we get a response from Lenovo? It's similar issue to DPST (Display Power Saving Technology) where the system will dim the screen when it's black. Something in the Oreo build for the Tab 4 8 is playing up. I got mine as a gift and was loving it till the update. I didn't have this dimming on Nougat. And yep auto britness is off and so is addaptive display
