I have question about full screen on the phone (Letterbox scale)

Hello,

I have question about full screen on the phone

first,I cohice Letterbox scale to export my game and play on my phone

but in the screen right side,it show me a large piece of white.

Next time I choice Letterbox integer scale

but still show me a large piece of white,like picture:

whatever I choice what,it show me the same result.

I know my game window size is too small so it show the piece of white.

SO,how should do I solve problem,I hope not to change window size,because it's a big deal.

One way to fix this is to use the "Scale Outer" option instead. This will scale full screen to the outer border of the project's window size.

If that doesn't work then I have a fix that uses Cordova when exporting/testing on devices as I had the same problem a few months back.

Does anyone know?

Thank you!

Finally I fix this problem

I use unbounded scrolling to "yes",and the screen move to middle

and choice Letterbox scale,finally,I create a black sprite to the bottom

the screen is on middle,and the piece of white become black

that's what I need!

although this method looks like not normal haha...!
