A screen projection control method, storage medium and communication apparatus are provided. The screen projection control method includes: a screen projection receiving end receiving screen projection request information from a first screen projection sending end; determining, according to the screen projection request information, whether a third screen projection sending end that has triggered an interference-free mode of screen projection exists in at least one second screen projection sending end that is performing screen projection, wherein enabling the interference-free mode comprises stopping accepting a screen projection request; and if the third screen projection sending end that has enabled the screen projection interference-free mode exists, the screen projection receiving end sending response information for refusing the screen projection request to the first screen projection sending end.
