Which operating system is best Linux or Android?

Linux OS is for Desktop & Server while Android OS is for Mobiles. Is that completely correct? Linux OS, precisely speaking Linux kernel is the most popular OS while Android is a framework built on top of Linux kernel. So every Android device is running Linux kernel as well but every Linux device doesn’t have Android.

Can Android run Linux?

In almost all cases, your phone, tablet, or even Android TV box can run a Linux desktop environment. You can also install a Linux command line tool on Android. It doesn’t matter if your phone is rooted (unlocked, the Android equivalent of jailbreaking) or not.
