S7 Dims to Minimum Brightness and turns off Auto-Brightness BY ITSELF

Hello everyone!

So I recently got the new S7 software update, happened about 4 or 5 days ago. Update feels great- messaging app is way faster, and certain QoL changes are great.

But now, my phone will go to its minimum brightness and turn off auto-brightness all on its own! I did a settings reset already, and called the S7 tech line and they said it was a software bug/issue, and that I would have to wait for a patch (which is what I expected).

Fast forward to now, and I really can't take this anymore. Phone is impossible to use outside, because the screen is so dim I literally can't see anything on my phone, and turning it back to highest brightness + turning auto-brightness back on does nothing, because the phone will just do the same thing in about 10 - 30 seconds.

On top of that, when it does this weird minimum brightness thing by itself, it also minimizes and tabs out of anything I have in fullscreen, and turn it into the widget that displays the video in the corner but puts me back to my homescreen.

Power saving modes are completely off, and Smart Stay is on.

Please, please help! This is driving me to my wits end. Appreciate any input and info you might have!

Boot into safe mode. If it stops happening, it's an app that you need to change your settings on since the update changed a lot of little and big things. Do you have a eye relief app? One that blocks the blue light? Also, the update has a built in blue light filter with brightness adjustment. Go to Settings and turn it off and your brightness up. Look around at all the changes. If you want to experiment write down what you're doing so you can undo it if you mess up something. Good luck.
