How do I show fps in Android 11?

Open Developer options and scroll down to the debugging section. Under this section look for the “Show refresh rate” option. Flip the toggle beside the option to turn it on and you should see your current refresh rate on the top left corner of the screen.

On Steam, open Settings > In-Game > In-Game FPS Counter . Select a location in the drop-down to turn it on. The next time you launch a game, you’ll see your frame rate displayed in the corner using dark gray text (though you can check the High Contrast Color box to display it in more readable text).
