Please deactivate the existing device owner first. ### MIUI & HyperOS ```text java.lang.SecurityException: Neither user 2000 nor current process has android.permission.MANAGE_DEVICE_ADMINS. ``` Solutions: - Enable `USB debugging (Security setting)` in developer options. - Or execute activating command in root shell. ### ColorOS ```text java.lang.IllegalStateException: Unexpected @ProvisioningPreCondition ``` Solution: Use OwnDroid testkey version ### Samsung ```text user limit reached ``` Samsung restricts Android's multiple users feature. There is currently no solution. ### Create work profile / user On most devices, creating work profile is not allowed by the system when the device owner exist. Because the system add `no_add_managed_profile` user restriction when a device owner is set. Device owner can't modify user restrictions set by the system, but if your device is rooted, you can disable this restriction by executing the following commands in adb shell. ```shell pm set-user-restriction no_add_user 0 pm set-user-restriction no_add_managed_profile 0 pm set-user-restriction no_add_private_profile 0 pm set-user-restriction no_add_clone_profile 0 ``` Some systems disable the feature of adding users in Android settings once a device owner is set. You have to create users in OwnDroid. Or if you have root, run the above command in adb shell to remove that restriction. ## For advanced users ### API OwnDroid provides an Intent-based API. You need to set the API key in settings and enable the API.
