The multi-operating system device comprises a processor, a transceiver, and an output device. The processor is configured to host a first operating system in the foreground and a second operating system (OS2) in the background, or vice versa. The output device is configured to be controlled by an OS hosted in the foreground. The transceiver is configured to receive a S1 from a notification device over a communication system, the S1 indicating a notification associated to the OS2. The output device further is configured to output the notification associated to the second OS2 when the OS1 is hosted in the foreground.
