Scene number effect apk file size?

hello every one
I want to know if I merge two scene and make it one scene my apk file size will reduce or not?
thanks

Not really, you might shave off some Kilobytes. Depending on how large your scene is. Reason for this is because .scene files don’t actually contain any object data.

Merging scenes may actually increase loading times.

It’s more the size of your scenes that affects the size of the build, regardless what platform you choose to build to.

If you merge your scenes, the final scene will most likely increase in size and you will gain nothing, except that your game is no longer seperated into several scenes. Assuming that your seperation into scenes made sense, you have sacrificed nicely seperated scenes for little to no build size reduction.
