pls tell me how to reduce apk size ?
thanks in advance

Your game built with Unity got the UnityPlayer inside it so it can run the game you made in Unity, so it has some extra mb.

Unity Remote isn’t a ‘Unity Game’ it’s just an application, the game actually runs in the Unity editor while its visual content is streamed to the target device.

As Vitor_r mentioned, your built apk includes Unity libraries.

Also, your built apk size is not reflective of your installed app size.
