What worked for me was uploading my 19 second ringtone on OneDrive and selecting it from there.
I have a Pixel 2 and have specific ringtones for various contacts however I when I edit the contact to change the ringtone, it doesn’t let me hear what I’ve chosen. This wasn’t the way it was when I first got the phone. What’s going on ?
This does not show how to check a contacts ringtone on the pixel 2xl. I want to see which one was assigned
previously, do I can change to another.
Neither do I, Pixel 5, excelent phone. Impossible to customize your ringtone…actually this is a step back in a lot of ways.
PD – pasting the song on ringtones folder Won´t work
put the .mp3 file in the ringtones folder first
No this did not help me at all. I used to be able to set a special ringtone for certain contacts but I cannot find a way to do so with my new Google Pixel 2XL. This description did not work or have the options to do so.
