Hi everyone,
My Mipad 4 installed MIUI 10.2.1.0 stable.
It have a bug that you can't view YouTube videos with full screen mode, only 16:9 available and you can't zoom to full screen.
I already go to settings > full screen display > full screen mode and switch YouTube to on but when you back to settings or do anythings, it switch off immediately. This problem also occurs similar to other applications that i want switch to full screen mode.
How to fix it? Please!
Thanks you so much!
