Google have started to prevent older APKs being installable on Android 14 and above. This means that the universal helper app cannot be installed by simply opening the APK on the device.

In order to install the universal helper app on any device with Android 14 or above, you will need a Windows or Linux PC or a Mac in order to connect to your phone along with some basic Android tools to push the APK to the device. 

Google's ADB tool can be downloaded from the links below: (Click the fading zone below to expand)

For instructions on configuring your device to connect via adb please see the following information:

Once you have a working adb connection, you need to run the following command from the command line/terminal on your computer:

adb install --bypass-low-target-sdk-block FILENAME.apk

where FILENAME.apk is the filename of the helper apk you should download to whatever you are running adb commands from. Remember to allow all permissions when starting the helper app else it might not work properly.
