What should I do if the ringtone of red rice mobile phone is loudest?

Restart the phone and see if it works.

Still not working. Excuse me, did your mobile phone get root permission? This may be caused by an application software conflict. Please back up the important data (contacts, text messages) in your mobile phone. Notes, etc. ), and then open Settings ~ Backup Reset ~ Restore factory settings. Try again and see if this phenomenon still exists.

If there is no such phenomenon, the application you downloaded should be in conflict. I suggest you check it carefully.
