Work with CA certificates
If a CA certificate gets compromised, or for some other reason your organization doesn't
want to trust it, you can disable or remove it. To do so, follow these steps:
1. Go to All apps screen and touch Settings.
2. Under Personal, touch Security > Credential Storage > Trusted credentials. You
will find two tabs:
3. To examine the details of CA certificate, touch its name.

of your phone.
User displays any CA certificates that you have installed yourself.
4. To remove or disable a CA certificate, scroll down to the bottom of the details
screen and touch either Disable for system certificates or Remove for user
certificates. When you disable a system CA certificate, the button at the bottom
of its details screen changes to Enable, so you can enable the certificate again if
necessary. When you remove a user-installed CA certificate, it is gone
permanently and must be re-installed if you want it back.
5. In the confirmation dialogue that appears, select OK.
