The way I have my phone setup that Screen Rotatation (found in the quick tools pull down bar) is not activated.
This works for me because I do not wish to use my phone in landscape mode ever, UNLESS I use YouTube.
YouTube normally will auto-rotate if you flip your phone. (Note: this is with Screen Rotation off still)
Right now, no matter what, I can't get my screen to rotate. With the feature on/off, using YouTube, Messanger, anything.
I am stumped. I tried calibrating the Gyroscope. Nothing.
So if anyone has any suggestions. That would be great.
