Why did the SMS ringtone of my mobile phone become an incoming call ringtone? I can't reset it. Lenovo a789

I'm sorry for the delay in your use.

If you can't customize the non-system ringtone file, or it will automatically return to the default after setting, I suggest you try to confirm and operate the following contents to see if it can be improved:

1. When this problem occurs, please confirm whether the PC is connected to realize the USB flash drive function. If there is, it is normal, because when the USB flash drive function is realized, the media files of the fuselage are being read and used by the PC.

2. It may be caused by some third-party software conflicts. Uninstall recently installed suspicious software.

3. Confirm whether the customized ringtone media file is stored in the external SD memory card. It may be related to the compatibility of the SD memory card used, or try to replace other SD memory cards for testing.

4. If it doesn't work, it is recommended to try to restore the factory settings of the backup data (please pay attention to backup the text contact and SMS, otherwise there is a risk of loss). If the above operation can't solve the problem, I suggest you go to Lenovo maintenance site for inspection and maintenance in time.
