I was playing around on with the Developer settings of my S22 Plus, and I found this method. First, you have to enable developer mode.
How to Enable Developer Mode:
Open your settings application, then scroll down to About Phone. Then click Software Information. Then tab the build number seven times. It will make you put in your phone's password. After putting it in, go back and you will see a new option called Developer Options.
Scroll down, then click GPUWatch. Enable it by clicking the toggle. It will show the FPS, Load, and some of the information. You can add some more actions by clicking the plus icon. Then you can show the widget over the screen. Your notification shade will allow you to hide or turn off the widget.
That is all. Does this work on all Androids? Or just Samsung? God Bless and Tech Talk To You Later!!
