How to remove KINGroot?
Firstly, soon after uninstalling KingRoot be sure to get another SU management app, to protect your device against malicious attacks since it has elevated privileges than a non rooted device,

A checklist just in case;


Check if KingRoot is enabled as device administrator (under settings≥security), sometimes it's difficult to uninstall apps with such privileges
Try to uninstall the app from  within itself, rather than dragging to uninstall (you will need to reinstall su binaries with this method, but if your goal is to just get rid of KingRoot for another SU app it's worth a go)
Navigate directly to /system/app/ and search for a package with name com.kingroot.kinguser and delete the contents.


If the app is still stubborn, then try the PC method

Connect your device via  USB with debugging enabled,

On your PC open ADB terminal and type the codes one by one

# mount -o rw, remount /system

# am kill com.kingroot.kinguser

# pm uninstall com.kingroot.kinguser


Check if the app is removed
