I installed the App ringtone maker and made a custom ringtone of 20 seconds. I saved it and set the same as my ring tone. But Unfortunately, that ringtone is not playing, i tried two three different songs but i cannot set that customised part of song as my ringtone , what can be the problem here ?
Firstly I would suggest you to try Ringtone Maker app by microsoft it worked fine for me.
Now if you are using a pc ringtone maker just take care of these restrictions
A MP3 or WMA file
Not protected with digital rights management (DRM)
Less than 1 MB in size
Less than 40 seconds
Must have the genre "ringtone"
File must be copied directly from PC to phone's Music or Ringtones folder
