Different rotation speed

MIT App Inventor Help
1

I take a small picture and start rotating it constantly.

When I touch it with my finger, the picture starts to rotate faster.
When I remove my finger the speed decreases.

I'm guessing it's because of the refresh rate.

Can this be controlled programmatically and see the speed of be maximum.

Can you provide a small example project that replicates this behaviour ?

I send small video. When I touch the picture - rotation is faster.

Testing with companion using app on Chromebook and a real device (Pixel 4a, Android 12), I am unable to replicate the behaviour you describe/show. I tried at different speeds for the clock as well.

I get this effect when using a mobile phone with a 120Hz display.
It is not seen in the other display as in the Google Pixel 4a.

I suggest to save energy Android reduces the frequency and only when the display is touched it works at 120Hz.

Is there a programmatic way to always have the display use 120Hz?

Maybe in the device settings.
