Test your mobile game projects on your PC, and get the Camera, UI, and game feel just right.

Now you may be wondering — “Hey this looks good and all, but what makes this more than just a skin on top of my normal Game view in Unity?” I’m glad you possibly asked this question! Here are some of the great features that Device Simulator gives us:

Tons of resolutions to choose from — if you can think of a device, it’s here!
  • The Device Simulator enables touch controls vs keyboard, so please keep this in mind when testing! Your mouse cursor simulates a screen tap on click, which can help with testing touch controls.
  • Click Highlight Safe Area to draw a rectangle that suggests where the deadzone for your game should be. If you follow this indicator, your game will look great even if your player’s phone has a notch!
The safe area is outlined in green. This example certainly helps to understand where UI elements should lie!


If you are a mobile game developer, I highly encourage you to go back to your old projects and take advantage of the Device Simulator feature! I have found it incredibly helpful with pushing updates for some of my older projects.
