Ever received Disabled by Administrator, encryption policy, or credential storage error in Android before? Every regular Android user must have at least once encountered some applications that require extra permissions when downloaded and installed through Google PlayStore. Some apps even request for permissions to write notifications screen, control brightness, etc.
This mostly comes up when trying to disable security on your device. Just in case you are getting the notification message similar to the one above then there is an app or some apps having Device administrator permission e.g Google Smart Lock.
Fixing this is quite easy following the below steps:
#1. Unlock your device, Click on ‘Settings’ then ‘Security’
#2. Depending on your device, after completing the above step, find “Clear Credentials” and finally click ok to clear the credentials (you won’t lose any file).
#3. Navigate back to “Security Settings” then find “Device Administrators” and finally click on “Clear” (untick) all checked boxes.
#4. Go to “Settings” then “Screen Lock” and the options to disable security will be available again.
Please note that if this doesn’t work, try to Restart the device and try the process again.
