Are rooting apps properly root the phone?

Hello Everyone, Today I will talk about everything about rooting. 

For me root is permission, with this you can modify your android system & customize your phone. 

Are rooting apps properly root the phone?

Many users trying to root their phone using some rooting apps like kingroot. 

& I don't think any android app can root any phone perfectly, Many rooting apps are fake. 

So if you want to root, then root your phone with laptop, 

Install kingoroot on laptop, connect phone with usb & try to root.

Thanks for reading.
