What's com.superthomaslab.rootessentials? What is com.superthomaslab.rootessentials? Having root access, no icons no name, just a package name. Please note that this app isn't installed on my devvice
That app was installed at one point and granted root, then later uninstalled which is why the package name is showing up in SuperSU with no icon instead of the application name. You can test this with any app you've granted root access to. Uninstall it and the same thing will happen.
