Caller tune function allows the caller to hear the 

tune which is set by the call recipient.  

1. If you are the call recipient,

    You can modify/remove your caller tune option 

on [Me] page - Settings - Function - Caller tune.

2. If you are the caller,

You can turn down your phone volume or let the 

call recipient modify his/her caller tune when you

feel uncomfortable.

Tips:

After somebody calls you for the first time, 

he/she may hear your new caller tune.

Ensure a stable network and you and your 

contacts use the new imo.
