If you are developing an application for mobile or tablet in Unity, it will be beneficial for you to see the test stages of this application in a simulator. As a result, it's important to know what apps look like on many different devices and screen sizes, and to fix bugs beforehand.

You can use the Device Simulator feature of Unity Editor for this.

To use Device Simulator you have to follow the below path.

• Select "Window" from the menu above.
• Select "General" and then "Device Manager" from the window that opens.

You can switch Game or Simulator in the upper left part of the screen that opens.

If "Device Manager" does not appear here, the following steps must be followed to activate it.

• Choose "Window" and then "Package Manager" from the menu above.
• Click on the gear icon at the top right of the screen (to the left of Search)
• Choose "Advanced Project Settings".
• "Enable Preview Packages" is marked on the screen and the screen is closed.
• Return to the "Package Manager" screen and select "Unity Registry" from the top left menu (to the right of +).
• "Device Simulator" will appear on the right side. It is installed by pressing on it.
