Installing root certificates on the device
A root certificate is a public key certificate issued by a trusted certificate authority (CA). Root certificates are used to verify custom certificates and guarantee their identity.
Your administrator can specify root certificates to be installed on the device. On devices operating in device owner mode and in a work profile, these certificates are installed automatically. In personal profiles, you will get notifications and have to install each certificate manually by following the instructions below.
To manually install a root certificate on the device:
- Open the device Settings.
- Navigate to the security settings. The path depends on the device model and operating system version. For instance, you may need to tap Advanced settings → Security or Security & lock screen → Credential storage.
- Tap Install from Phone Storage / Install from SD Card or a similar option.
- Tap CA Certificate.
- On the confirmation window, tap Install Anyway.
- In the appeared file manager, select the required root certificate.
On some devices, the downloaded certificates may not be displayed in Recent files. Please wait for 3-5 minutes and open the file manager again. The waiting time depends on the device model. If after 3-5 minutes no files have appeared, go to the Internal storage\Download\kesm_certs or SD card\Download\kesm_certs folder and select the required root certificate.
The root certificate will be installed on the device.
