When we uninstall some Android apps we receive “Uninstall Not Successful” error. This is a common situation for most of the applications. There are two reasons for this issue, if you try to uninstall Android apps, that received administrative privilege rights or if you try to uninstall system or preloaded app without root permission.
This post I’m going to discuss how to uninstall app that run as an administrator. We can see this security feature on Android 2.2 or above operating systems and it give better protection to your phone. Before uninstall this kind of special permission received apps, we have to disable those apps administrative rights.
To do that, first go to the “Settings>Security>Device Administrators”. In the next step you can see all the administrators apps like following screen shot.
In the next step tap on the “Deactivate” button, like following screen shot.
Now that Android app doesn’t have any admin rights. Again go to “Setting> Apps” and uninstall a program that you want or if you have 3rd party Uninstaller you can now use it. Most of the time we can see this special feature includes security and tracking Android applications. After user enable this it, those android apps can promote a new password, Monitor user activities, Lock device, Wipe phone data.
This method you can’t remove pre-installed app, in order to uninstall user need root access.
