Canvas or arrangement size problem?

[Usane]

Hello.

I save Image from a vertical arrangement which size is calculated and saved to variables after this "virtual screen" which is an arrangement is opens.
Load screen

save screen.

After I save I set this picture to a canvas background,

Looks like this: (and should looks like this in my opinion)

And the load screen looks similar after pick one from a listpicker:

And it is really looks like this on my 7" lenovo tablet. (android 9)
BUT:
On my two samsung phone, (one is android 9, the other is android 12)
Not.
It looks like this:

Everything in percents and fill parent to be responsive.
Where could be the problem?
I cannot upload my aia, it is 30MB, but I try to make a simpe app for someone try on different devices.

Update:
If i turn off the status bar, the it fit on the samsung phones too, but I want the status bar on, so I may play a little with the size. Still don't know why is different on the Lenovo Tab.

Don't mind.
Changing percent to fill parent fixed it.
