What happens if I disable Android apps?
All the system apps on android are not meant for good sakes, some of them are essential while others are resource eaters. In such removing these useless system apps will definitely help you to boost your device performance and improve battery life.
On the other side, if you end up uninstalling some essentials system apps (like Finder app, Carrierhub, KLMS Agent, and SKMS Agent etc) it may cause some error to access some features on the device. So, make sure to check the other details about the app before you proceed to remove or freeze system apps on your android phone to avoid any error.
How to Re-install an Uninstalled App.
Removing an essential system app from android may cause some anomaly on the device while accessing some features on the device(i.e. disabling KNOX system app from Samsung android will disable the security module ).
At any point you find that you have accidentally uninstalled an essential system app from the device, don’t you worry, there is always a method to re-install an uninstalled app using ADB command.
Just type the following command on the ADB shell and followed with the app package name.
adb shellpm install-existing NameOfPackage
This will restore the uninstalled app as the app applications truly aren’t fully uninstalled from your device. They are just being uninstalled for the current user (user 0 is the default/main user of the phone). So, if you omit the –user 0 and -k part of the uninstall command, the command won’t work.
You can also use a manual OTA update to restore all the deleted system apps from the device.
