Hi, as per my knowledge when iQOO neo 6 launched that time iQOO said they are providing 2 Android versions and 3 yrs security package. When neo 6 launched that was based on Android 13 version.

I think most of the iQOO users have neo 6 smartphone more than others iQOO smartphones.

So, I kindly request you to please give us Fun Touch OS and Android 15.
