Usually people who successfully root their Android phone and tablets wiould not want to revert back or unroot it. The primary reason being that rooting your smart phone grants you a super admin access and control of your device.
As you most likely know, rooting your device will in most cases void your warranty which lasts usually for 12 months. But is it worth the risk? A lot of people people thinks it does.

What happens when you uproot or unroot your Android phone?

Usually when you unroot your phone, the device goes back to the factory default and you will once again be denied the super administrative access to certain contents and files in your Android phone.

It is safer to keep your smart phone the way it is when you bought it, that is the factory default setting. So if as you asked, you want to know if unrooting your Android phone will make you avoid future problems, the answer is YES. Your device will be more protected and you will trade it with your administrative (super) status with an unrooted Android phone.

What about your Warranty? WIll it come back?
Since rooting your phone will void your warranty, what about unrooting it? A lot of people have asked this question. The truth is that once your warranty is voided, then it remains like that. Unfortunately, when you unroot a formerly rooted phone, not every manufacturer sales rep will be able to easily detect if it has been rooted or not.

A Quora user, Gautam Regal, answered this particular question excellently. He wrote:

"As long as your phone doesn’t say modified in the about phone section located at the way bottom of the settings and you’re running a completely stock ROM, then you should be good.

They’ll know that your phone was rooted if your flash counter is not 0 (boot into recovery mode to find out what your flash counter is). If your flash counter is not zero, then you need to download the app called triangle away in order to reset your flash counter (do this before unrooting your phone). Easy step to avoid tripping the flash counter? Don’t flash a modified ROM through ODIN.

They’ll also know your phone was rooted if your phone says modified though. When you unroot, notice that your phone still says modified. You then have to boot into the stock recovery (not recovery mode) and then factory reset from there. That should get rid of the modified status. Hope this helped."

So you may want to go ahead and unroot or ‘uproot’ your phone if your not sure about the security of your device. If not, its cool to root your device and get total control of your property!

What about if you used an app like SuperSU? Will it reset your phone back to factory setting if you unroot it through the app?
