I apologise if I'm posting on the wrong forum. I recently purchased a tablet/laptop - Samsung Galaxy Tab Pro S (SMW700NZKAXSA) which runs on Windows 10 and was manufacturer refurbished. However, when I got it and opened it up, the screen was really bright, assuming it's full brightness. I went to turn it down using the Fn+F keys to change brightness but they didn't do anything. So I went to the settings to adjust the brightness scroller thing but it didn't work as well. I've been searching and trying to fix it for the past few hours but no luck. Most I've searched involved drivers but updating them didn't work. Does anyone have an idea of how I can fix this?
