I've an s8 plus and struggling to get a ringtone to stick regardless of whether I use the stock ringtones or one of my own it constantly resets itself to default option.
Could you give us a little more info on this?
When does this usually reset after you've set your ringtone?
Is this after using a certain app, or do you reboot the phone?
Which ringtone are you trying to set/ where did you get this from?
Any joy on this since you posted? If not, is your phone definitely in Standard mode (Settings > Display > Easy Mode, and check that Standard mode is enabled)? And were you trying to set it by Settings > Sounds and Vibration > Ringtone > (select your ringtone) > Home icon?
