Screen size not same when i build to apk

Hii, i’m a newbie with unity.

i try to make an aplication to android device. my apps look like this.

i don’t know, but when i try build the apps and install on my device, the apps look like this. the background and particle system is fit to my screen device but the canvas, panel and button being small like this.

How can I fix that ?

Thank you in advance !


Unity version : 4.7.1
Android device : Nexus 5

Try changing the game view from free aspect to match the device resolution. It should show the same issue. Now look at the canvas scaler and your anchors too see if they are setup correctly, maybe take a look at the learn section about ui anchors.
