Remove this option from device

Hi i0xlkvmkav0z​. Welcome to our forums. I'm not sure which option you're referring to. Could you please provide a few more details?

• What option do you have in mind? 
• What happens exactly when you launch the game? 
• What device are you using? 
• What is your device's operating system and version (Android/iOS)?

The more information you can share, the easier it will be for us to understand the issue and help you.

Thanks!

1. The option is to make the full screen and restart
2. When I tap on this option the game gets restart and if I want to open other app and if I want to play fc again the option is on screen
3. The device name is samsung A05
4. Samsung 

Thanks for the additional information and the screenshot. Based on what you've shared, the fullscreen button shown in the bottom-right corner appears to be a Samsung or device feature rather than an FC Mobile feature. Unfortunately, we can't remove or change device-specific overlays from within the game.

You may want to check your phone's Game Booster or Game Launcher settings or other display-related settings to see if this overlay can be disabled. If you're unable to find the option, Samsung Support should be able to advise you on how to turn it off on your Galaxy A05.
