DevicePolicyManager is a public class for managing policies enforced on a device. You get a handle to the DevicePolicyManager as follows:. This section describes how to use DevicePolicyManager to perform administrative tasks:.
This section describes common password-related tasks. The password quality can be one of the following DevicePolicyManager constants:. Beginning with Android 3. For example, you could set a policy that states that passwords must contain at least n uppercase letters.
Here are the methods for fine-tuning a password's contents:. You can set the maximum number of allowed failed password attempts before the device is wiped that is, reset to factory settings. This method takes a length parameter, which specifies how many old passwords are stored.
When this policy is active, users cannot enter a new password that matches the last n passwords. This prevents users from using the same password over and over. This policy is typically used in conjunction with setPasswordExpirationTimeout , which forces users to update their passwords after a specified amount of time has elapsed. You can set the maximum period of user inactivity that can occur before the device locks. You can use the DevicePolicyManager method wipeData to reset the device to factory settings.
This is useful if the device is lost or stolen. Often the decision to wipe the device is the result of certain conditions being met. For example, you can use setMaximumFailedPasswordsForWipe to state that a device should be wiped after a specific number of failed password attempts. The wipeData method takes as its parameter a bit mask of additional options. Currently the value must be 0. Beginning with Android 4. Note that this doesn't have to be a permanent disabling.

Once the scan is complete, the app would display the apps that have the admin privilege. So this how you can disable the android administrator settings on Android devices manually and using the third-party application. When an unauthorized application gets the admin privilege, it may cause severe damage to the phone, and hackers can take control of your phone and steal personal pieces of information. Therefore, we recommend checking what resources it wants from your device before installing an application.
Also, ask yourself why it requires permission to use that resource , and only grant access when you are sure that the app is secure. Also, make sure that you have a good antimalware application installed on your Android device to catch the suspicious apps. There is no inbuilt app provided by Android to search for the application that is secretly enjoying the device admin privilege.
So you require a third-party Android app, specially designed for that purpose, to find hidden admin on Android. In Android, the device administrator is the special privilege given to some apps, so that they could perform some tasks by themselves, like locking the phone when it is stolen. After reading everything you have discussed, I now know where to begin to fix this issue.
Just one question,please: There are system apps with permissions and app links that are frozen. They can neither be turned on or off. Can you advise me on how to tackle this. Again thanks for all your help. I can not load any apps from Google play store. Save my name, email, and website in this browser for the next time I comment.
What is Device Administration? You would see the applications that have device administrator rights. Tap on the app for which you want to disable the privileges and press Deactivate. Confirm on prompt. The admin rights are now removed, and you should now able to uninstall that app. How can I find a hidden device administrator in Android?
