How do I understand what sample_count value to set?

https://docs.rs/miniquad/0.4.6/miniquad/conf/struct.Conf.html#structfield.sample_count

For example, on the computer I set 120, 300 and more and no problems, and on the Android phone the maximum was 2, and what if there is a phone that pulls a maximum of 1?

I need to know what affects this indicator and is it possible to change it during execution?
Also, is it possible to somehow get the maximum allowable number for the current device?
