How to control user installed apps? Device Pre-installed Apps(Camera, Calendar, file manager etc. ) have options for 'Force Stop' and 'Enable/Disable' app. And, for User installed apps(from PlayStore etc.) have only options 'Force Stop' and 'Uninstall'.

I have set some applications to start from boot. Mostly, user apps are set to start, while  I touch them only. But, some user apps start automatically, and consumes RAM. I will Force Stop/remove those apps from RAM. But, it starts again after few hours.

Is there any method to disable such apps rather than uninstalling those apps.

On a rooted device, it is possible to disable/enable user apps using a terminal emulator.

To do so, open a terminal of your choice, enter

su


to acquire root privileges and then enter

pm disable &lt;packagename&gt;


Take care to replace &lt;packagename&gt; with the package name of the app you wish to disable (for example, if you wish to disable WhatsApp, your command will be pm disable com.whatsapp).

To revert the process and thus enable a disabled app, acquire root privileges and issue

pm enable &lt;packagename&gt;


Again, remember to replace &lt;packagename&gt; with the package name of the disabled app you wish to enable.
