My screen has strange code

[1234567f]

Starting on the left top corner, there is strange code on the screen on my phone (it changes) Below is an example. It doesn't go away even when I open an app, or even when the phone is blocked. Already shut down, took out battery and this doesn't go away. Any help is appreciated. Thanks.

Go into your settings>developer oprions and (uncheck) show cpu usage. That should do it.
