Root

Hello AshishN2001,

In general 'root access' may be referring to an unauthorized modification of iOS.

This page can help out with providing information on that topic: Unauthorized modification of iOS - Apple Support

iOS is designed to be reliable and secure from the moment you turn on your device. Built-in security features help protect against malware and viruses and secure user access to personal information and corporate data. Unauthorized modifications to iOS (also known as “jailbreaking”) bypass security features and can cause numerous issues such as security vulnerabilities, instability, and shortened battery life to the hacked iPhone.

Apple strongly cautions against installing any software that modifies iOS. It is also important to note that unauthorized modification of iOS is a violation of the iOS and iPadOS Software License Agreement and because of this, Apple may deny service for an iPhone that has any unauthorized software installed.

Cheers.

Hey AshishN2001.

What you're asking isn't something that can be done by anyone on this forum. If you've got a question about the configuration of your iPhone or the validity of any of the software installed, please Get Support from Apple directly.

Take care.
