If you have updated your Nubia device to to Nubia UI 4.0 and cannot remove its default Nubia launcher then this post will help you.
I just updated my Nubia Z9 Mini to Nubia UI 4.0 and will say this update is awesome!. But i always hate the launchers which contain all icons on desktop in unsorted order. I am very irritated by this because i know if i have to launch Twitter or WhatsApp the letter comes at end and icon will be at end of launcher. To get rid of this i installed Nova launcher (holo launcher is my favorite). Follow the below steps to set default launcher or other default apps in Nubia UI 4.0.
- Install your favorite luncher.
- Go to settings -> Apps -> at top right there is drop down list. Press it. -> Select your launcher.
You are done setting default launcher in Nubia 4.0.
