How to unroot your android smartphone? in case you want to sell your phone or want to claim warranty then you must unroot your phone.
There are few ways to unroot android smartphone, like i said in my previous article, you can also use vroot to unroot the phone.
It's very simple and easy to do, vroot will detect whether your phone have already root or not and then if you do, there will be unroot button, just press that button.
But some people report that this unroot method doesn't really a clean unroot, although this not happened to me.
Another way to unroot android smartphone is to do factory data reset or factory hard reset, this method surely removed the su binary.
And if you still not sure, basically you just flash your device, this guarantee works cause basically you'll get fresh install of your android.
