        btnDeviceLauncher.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                Intent startMain = new Intent(Intent.ACTION_MAIN);
                startMain.addCategory(Intent.CATEGORY_LAUNCHER);
                startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(startMain);
            }
        });

First of all, a launcher application is also launched by an Intent. So if you write your own launcher application and set that application as your default launcher application, the next time there is an Intent for the launcher application, your own application is going to be launched, not the previous launcher because the Intent is for the launcher application and your application is the launcher application right now.

So if you want the original launcher application to be launched from inside your launcher (although I don't think it will look the same as when it was actually the launcher) you will have to launch it manually using the package name as described here: start application knowing package name.

To get the package name of the actual launcher application refer: How can I get the package name of the current launcher in android 2.3 and above?
