The invention discloses an event processing method and a device, a terminal and a storage medium, and belongs to the technical field of networks. The method comprises the following steps: detecting ato-be-processed event; if the event is a preset event, sending a resource processing request to a terminal operating system according to the event; and processing the event based on the target processing resource allocated by the terminal operating system and used for processing the event. By sending the processing resource request to the terminal operating system, the processing resource requestis used for indicating the processing resource required for processing the event, and the processing resource can be requested from the terminal operating system in advance before the event is processed, so that the performance loss event generated in the processing process is avoided, and the resource scheduling condition is optimized.
