According to your description, Root is the administrator user account of the mobile phone, which can access and modify almost all files in the mobile phone operating system, which may affect the stability of the mobile phone and lead to human failures such as crashing and restarting. According to the "three guarantees for consumers", Root belongs to the modification of operating system software and does not belong to the warranty scope. In order to improve customer satisfaction, Samsung provides Root customers with hardware maintenance (maintenance of components other than the motherboard, because after Root, the main components on the motherboard, such as memory and CPU, will generally be defective, so the motherboard will not be repaired) and free software upgrade services.
