New ACER ASPIRE R5 571TG - Screen won't auto rotate

Hello All

I am a new owner of the ACER Aspire R5 571 TG since last month. It came with Windows 10 if you did not know :-)

One of my issues right now is that in tablet mode, or any mode for that mattter, the screen won't auto-rotate.

I searched on google, youtube, here, I know i have the correct settings (in the notifications and in the display setting), I tied everything, and yet it won't rotate....very annoying.

By the way, it never worked, out of the box it as not working

Thanks for your help

Stephane
