myPhone Q-Smart Ringtone Issue: Unable to Set Bell, File Invalid Error in Audio Player

Phone number from Biedronka, new. A large number of ringtones to choose from. In the "Profiles" menu, I choose "General", then "Edit" and then the type of the bell. Unfortunately, after selecting the ring, the message "The phone's ringing does not play" appears. Files are also not played by the audio player installed in the phone. However, you can run an audio file sent from another phone. What's the problem?

The attempt to start the file in the player ends with the appearance of the message: "File ... is invalid".

It is probably about the audio file format, eg. Mp3, .wma, amr, etc. You have to check what formats this device supports and in such format upload audio files. The converter will probably be useful, so I recommend the FormatFactory program.

files in the phone are ".wav". MP3 plays.

So select the ringtones thrown in the .mp3 format. It may be enough to do a soft reset of the phone so that these loaded wav ringtones will work. You can find out how to do it online.
