AC Question

I root my android with kingo root and it install superuser in my phone.to make space I uninstall kingoroot but after some days my android unroot itself and superuser said su binary and when I try to install it it said insufficient storage but I have 2gb left. Some games and apps install normally but some apps can't install by error insufficient storage. The error start when my android unroot itself.I can't install or update apps like-any root app,what's app,and any Google app.
