Frame rate screen

I enabled the view of the FPS / Screen frame rate and see it was 54.
Is it normal that the frame rate of the screen is 54?
Is there no 60 fps possible?

Could you please share the build number (See Settings > About Phone), and tell us what batch the device is?
You can check the batch/variant by following this post:

Here you go.
Build number; 11.0.2+b1a2332.user
Batch = 2020

Also screenshot of the FPS. Apparantly you can’t screenshot the FPS… so you don’t see it.
