Is the message claiming the distortion of a Quranic verse in one of the applications false, or is it true, and the preservation of the Quran depends on alerting people, or does the noble verse "Indeed, it is We who sent down the Dhikr and indeed, We will be its guardian" have a different interpretation?

The Qur’an is preserved from कमी (deficiency) or إسقاط (omission), due to the Almighty’s saying: "Indeed, it is We who sent down the Dhikr (definition) (the Qur’an), and indeed, We will be its guardian." Any error or intentional distortion in its writing is discovered, and Allah raises up those who draw attention to it. The failed attempts to distort the Qur’an, despite the enemies of Islam having the ability to do so in the past, remain proof of its preservation.
