can i???

oke, thank you..

You can unroot it but Remember Once you root it the software is permanent cracked up even you unroot it .

If you really want to unroot its effect :-

Download your stock Rom of specific smartphone and recocer it by computer

Here's a tip :-

Download a  TWRP Custom recovery for your Samsung Galaxy note 4 (which is support ) After that download "Flashify"(You must be a root users To use this app but it is fabulous) after download It will pop-up about root permission and allow it then Click "Recovery image" then "Choose a file" (Note: Here a file is said that you download the Custom recovery from web(Some file consists Zip format so decrypt it))It will takes a few seconds to install .Al

After click reboot to access Custom recovery then select Wipe option then select"Advance wipe":-

Select all things except the "Dont Wipe the SD Card!!!!!!" then swipe to wipe

This will cuase the wipe all things even the software too but to remove the root effect so i have to tell you this !.(Better backup things in cloud and  SD card before attempt to such risky step!!!)

Sorry i can't tell you all details in Comment (Kinda huge one!!) Search in YouTube for instant Result.

Better Search "How to recocer it's stock Rom of Samsung Galaxy note 4"(This store can't let me to give you link)
