When we buy a new Android device we find that it comes with quite a few pre-installed apps. Manufacturers and operators take the opportunity to add their own applications and even game demos that in some cases we cannot uninstall.
These applications cannot be uninstalled like the rest of the applications that we download from Google Play or other sources because they have been added as system applications. To remove the factory applications we need to have our device rooted, although if we have Android 4.0 or higher we can disable those applications without being root.
Disable system apps on Android
Android 4.0 added the possibility of easily deactivating most of the applications that come standard on our Android device without being root, as long as they are not essential for the correct operation of the terminal. To deactivate an application, we only have to see the information of that application (Settings> Applications> All) and disable it. The system will not delete it from the internal memory but it will delete it from the application launcher and it will stop running in the background if it did. It’s like uninstalling it but leaving a copy in memory in case we later want to re-enable it to use it again.
Uninstall system apps on Android
If we have a device with a version prior to Ice Cream Sanwich or we simply want to uninstall a factory application completely now we need to have the device rooted. We have to delete the application from the folder / system / apps from any file explorer or application that can access that system folder. Next we will see how they are deleted from some applications:
The well-known ES File Explorer file explorer allows us to eliminate system applications from the “Root Explorer” that we find in its side menu. When accessing that option we will get several options and we have to choose “Uninstall system app”. When we see the list of applications, we only have to press for a couple of seconds on the application that we do not want and when it is checked, click to uninstall. It is always recommended to make a backup copy in case we delete a system application by mistake.
Titanium Backup, apart from being able to make backup copies of all our applications, also allows us to eliminate the factory installed applications. In “Copy / Restore” click on the application to remove and we click to uninstall.
With Root Explorer, which only has a payment application at 3.59 euros, we can eliminate those applications by accessing the system / app folder, activating the write mode (Mount R / W) and pressing for a couple of seconds on the application in question.
Another way to eliminate these applications is with Root Uninstaller, an application that will show us all the applications that we have installed, showing those that are from the system in red and that when clicking on them, the option to uninstall will appear. In all cases it is recommended to make a backup copy of the applications in case we have to reinstall them.
