Part of the benefits of having an Android device is being able to install an app on it. Installing is as simple as one, two, three; just search for your desired app on the Google Play Store and hit the Install button. Though installing apps is easy, they can be installed as either user apps or system apps.
User apps are installed in the typical way via the Google Play Store, Amazon Appstore, third-party markets, or sideloading. In contrast, system apps are apps pre-installed in the phone’s system partition with your ROM and typically, Android device users don’t have the access to the system partition. This means that, ordinarily, users cannot directly install apps to or uninstall from the system partition.
You can install user apps as system apps by using such apps as Titanium Backup, but you have to go for the paid version of the app to be able to enjoy such feature. However, there are other methods to install user apps as system apps without paying fees. Check out this guide for methods of installing ordinary user apps as system apps.

Installing a System App with ES File Explorer
For this method, you will need root access and the ES File Explorer app. You can download this app free from the Google Play Store.
- Configure ES File Explorer by doing the following steps:
- Launch ES File Explorer.
- Select Menu and choose Settings.
- Under Settings, enable the options for Up to root and Root Explorer. A message will appear, requiring you to confirm your action. You will also need to confirm Superuser access.
- Enable Mount File System.
- Go back to the app’s main menu.
- Get a copy of the APK (Android Package) of the app that you want to save as a system file by doing the following steps (skip to step 3 if you already have the app’s APK file):
- Install an app from the Google Play Store. For this guide, we will be using the app BioRhythms as an example.
- Launch ES File Explorer and navigate to /data/app.
- Locate the APK file that you want to install as a system app. If you don’t know the APK’s filename, simply go to the Google Play Store link of your chosen app. View the link and take note of the words after “?id=”. This will be your APK’s filename. For instance, the BioRhythms app link is https://play.google.com/store/apps/details?id=app.biorhythms. The BioRhythms’ APK is app.biorhythms-1.apk.
- Create a backup of the chosen APK by copying it to the phone’s SD Card.
- After creating a backup, long tap on the APK file and a menu will appear. Choose Cut. A blue arrow will appear at the bottom of the screen.
- Go back to the main menu and navigate to /system/app/.
- Drag the little arrow at the bottom of the screen. It will bring up the icon of the APK file.
- Tap the APK file and it will be transferred to /system/app/.
- Find the APK file in /system/app/. Press and hold it and a menu will appear.
- Select Properties on the menu. The dialog properties will show up.
- Tap Change and it will show the permissions dialog box.
- Check the boxes for the following permissions in the dialog box:
- User: Read and Write
- Group: Read
- Other: Read
- Select OK once the required settings have been made.
- Reboot your device.
You app is now saved as a system app.
Installing a System App via ADB
For this method, make sure that you have installed ADB (Android Debug Bridge) on your computer. You can get ADB by setting up the Android Software Development Kit (SDK) on your computer.
For Apps Installed on the Device
- Assuming you have installed the app on your device, go to the app’s Google Play Store link and take note of the words after “?id=” and ignore the rest. For the BioRhythms app, the link is https://play.google.com/store/apps/details?id=app.biorhythms. Take note of app.biorhythms.
- Connect your device to the computer via USB cable.
- Open the command prompt on your computer and type the following commands:
- Type the command
ls appfilename*(where “appfilename” is the app’s ID on Google Play Store; make sure you include the asterisk at the end). Based on our sample above, the command will be
ls app.biorhythms*. This command will display the app’s complete APK filename. In the case of our sample app, app.biorhythms-1.apk will appear on the screen. This is the app’s complete APK filename. Take note of this complete filename.
- Enter the following command:
mv apk_full_filename_here /system/app/
In the case of our sample app, the command above will look like this:
mv app.biorhythms-1.apk /system/app/app.biorhythms-1.apk
- The device will now reboot. Your app is now saved as a system app.
For Apps Whose APKs Are on the PC Hard Drive
If your copy of the app’s APK file is on your computer, you can do the following steps:
- Open a command prompt on your computer and navigate to where the APK file is located.
- Enable USB debugging on your device and connect your device to the computer via USB cable.
- Enter the following commands:
adb push apk-filename-here /system/app/
adb shell chmod 644 /system/app/
In the case of our sample app, the command will look like this:
adb shell chmod 644 /system/app/
- Your phone will automatically reboot. Your app will now be saved as a system app.
Congratulations! Your normal, ordinary user app is now installed as a system app on your Android device.
