A free program for Android, by j4velin.

This program switches whether an app is a system app or a user app by moving apps to and from the /system/app folder. Some apps have more functionality when deployed as system apps because they can access higher capabilities. System apps, on the other hand, cannot be removed. So, by transferring system apps from the /system/app directory to the /data/app directory, this app can likewise be used to change system apps to standard user apps.

A device may become inoperable if essential system apps are removed. Use this feature only if you are experienced and at your own risk! first, create a NANDroid backup! If you’re not OK with me providing no support in the event of a problem, don’t install this app.
