There are many software for sending text messages on mobile phones. How can I return them?

What do many softwares mean by texting? Is it automatic or did you set it yourself? If you keep sending messages you don't want, you should consider whether you are poisoned. If you know which softwares are constantly released, but you want to keep them, you can turn them off in the background, and then turn off the permissions of those softwares in the "Protected Background Applications" in the settings.
