I am having a problem in my fc mobile username

Hey 0z45xozu6wjs​,

How is your username glitchy exactly? A photo or screenshot of how it appears in the game might help us figure out what's causing the problem.

In the meantime, please try the troubleshooting steps for Android devices in this guide.

Sometimes, clearing your app’s cache and data can help fix issues.

Also, make sure you have the latest game version installed by checking for updates in the App Store.

It might also help to reinstall the game, as long as you have saved your progress online following this other guide.

Let us know how it goes.
