Videos not fun screen on iPhone Xr

Playing MP4 videos plays them ok but when you hit the expand to full screen to pay in landscape mode about an inch on one side isn’t filled and some on other side. It’s not even in the middle of the screen.

I’ve tried loads of different videos and it’s the same on all. I’ve got the lastest iOS ixpand app on latest version iOS.

Can we not have full screen? As t least make it in the middle it looks so poor lobsided. I presume it’s the app isn’t optimised for the new size screens but can you fix asap please?

Anyone else confirm please?
Thanks

i have an Xs and I can tell the app is optimized for the new iPhone screens. The issue you probably have is that the source video aspect ratio is not optimized for the new iPhone screen.

Is it true?i am going to buying one next week.

the aspect ration of the video itself will determin how it shows on the screen. most videos will play with a black bar at the top and bottom as they dont have the same aspect ratio at the iphone screen.
