How to uninstall or replace Joy Launcher? This morning my Android mobile started asking for permissions for a "Joy Launcher" app that I've never seen (or at least noticed before).  This appears to be an official app from the manufacturer.

I also found this article indicating that Google recently discontinued their Google Now Launcher, but I'm uncertain as to whether this has any bearing on my situation.

My biggest concern is that it's suddenly asking for unneeded permissions.  It seems unusual to me.  I haven't been able to disable it.  Can anyone shed some light on what's happening and/or any insight as to how I can remove or replace it?
I ended up disabling Joy Launcher and installing another launcher of my choice.  Joy Launcher can be removed from the startup items using any startup manager.  I very recently switched to the All-In-One Toolbox app, since the Startup Manager app I mentioned above in the comments has gone flaky lately.
