Installing a digital certificate

Use client and Certificate Authority (CA) digital certificates to enable
HTC One to access VPN or secured Wi-FI networks, and also to provide
authentication to online secure servers. You can get a certificate from your
system administrator or download it from sites that require authentication.
§ You must set a lock screen PIN or password before installing a
digital certificate.
§ Some apps such as your browser or email client let you install
certificates directly in the app. See the app's help for details.
1. Save the certificate file in the root folder on HTC One.
2. Go to Settings, and then tap Security.
3. Tap Install from storage.
4. If you have more than one certificate in the root folder, select the
certificate you want to install.
5. Enter a name for the certificate and tap OK.

Disabling an app

Apps, even if not used often, may be running in the background and
downloading data. If an app cannot be uninstalled, you can disable it.
1. Go to Settings, and then tap App manager.
