A mis-function protection method for mobile phones from RF noise interference includes the steps of: a signal detection circuit provided in a mobile phone, the signal detection circuit being operated to periodically detect a RF signal with a predetermined time period to determine outputting a signal; when firstly detecting no RF signal, no signal output from the signal detection circuit, alternatively when firstly detecting a RF signal, the signal detection circuit being operated to secondly detect the firstly-detected RF signal after a predetermined time; and when secondly detecting none of the firstly-detected RF signal, no signal output from the signal detection circuit, alternatively when secondly detecting the firstly-detected RF signal, the signal detection circuit being operated to output the signal. |
