Important: Even if the use of certificates makes the risks involved in remote 
connections and software installation considerably smaller, they must be used 
correctly in order to benefit from increased security. The existence of a certificate 
does not offer any protection by itself; the certificate manager must contain 
correct, authentic, or trusted certificates for increased security to be available. 
Certificates have a restricted lifetime. If "Expired certificate" or "Certificate not 
valid yet" is shown even if the certificate should be valid, check that the current 
date and time in your device are correct.
Before changing any certificate settings, you must make sure that you really trust 
the owner of the certificate and that the certificate really belongs to the listed 
owner.
View certificate details and check authenticity
You can only be sure of the correct identity of a server when the signature and the 
period of validity of a server certificate have been checked.
The phone notifies you if the identity of the server is not authentic or if you do not 
have the correct security certificate in your phone.
To check certificate details, scroll to a certificate, and select Options > Certificate 
details. While opening the certificate details, the phone checks the validity of the 
certificate and one of the following notes may appear:
Expired certificate—The validity period has ended for the selected certificate.
Certificate not valid yet—The validity period has not yet begun for the selected 
certificate.
Certificate corrupted—The certificate cannot be used. Contact the certificate 
issuer.
Certificate not trusted—You have not set any application to use the certificate.
Change the trust settings
Before changing any certificate settings, you must make sure that you really trust 
the owner of the certificate and that the certificate really belongs to the listed 
owner.
Scroll to an authority certificate, and select Options > Trust settings. Depending 
on the certificate, a list of the applications that can use the selected certificate is 
shown.
