Changing the Ringtone Bug

[agnisen07]

Please tell us some basic information before asking for help:
Model Name: ASUS Zenfone Max Pro M1
Firmware Version: 9
Rooted or not: Not Rooted
Frequency of Occurrence: Always
APP Name & APP Version (If your issue relates to the app): N/A
Whenever I try to change my ringtone to any downloaded tune, it works for 1/2 times but then reverts back to default. I have tried with both Internal and External Storage but the same issue occurs all the time.

Please can anyone suggest a solution?

Hi, we'd request you follow the below steps:
1. Clear system cache.
2. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check for any disturbance from the installed 3rd party apps.
