Ringtone NOT working

[Greg T]

Since I got my Cosmo, I've had an externally-boought-&-installed (by me) ringtone ... (Good bad ugly theme, with an *mp3 suffix
Suddenly it's stopped working - "this format is not supported."
How do I get it back?

[Greg T]

Why / how does an installed MP3 ringtone suddenly stop working on my COSMO?

[Zarhan]

Do other MP3's work?

Have you tried deleting the MP3, perhaps rebooting (to clear any caches) and then installing it again?

[Greg T]

UPDATE
I can now play the ringtone - I downloaded the "VLC" App ... BUT, But, but
It still won't play as an actual ringtone
I've worked out that if I can transfer ( Copy / paste via an intermediate machine ) my desired ringtone into the correct directory, it should play.
WHERE is that directory - can someone give me the file-path, please?

'/Ringtones'

LET'S TRY AGAIN

In Android, one should have a long list of ringtones available - yes?

I have only got FOUR & I can't transfer the MP£ tone into that list.
It's plainly a software fault
 - NOTE: "GBU" is the ringtone I have & want, but cannot load in the right place, OK?

The file paths are - :
1:  File Manager / San Disk SD Card / Ringtones / GBU.mp3 - it will play there, but I can't move it!
2: File / GBU - which then PLAYS - but I can't even shut it off - it loops & I have to restart the phone (!)
3: Settings / Sound / Phone Ringtones - which then shows a very limited list of four, ONLY
 { They are: Argo Navis / Atria / Backroad / Beat Plucker ) / - NOT WHAT I want, but that's all that is offered.

Plainly a software fault or faults ,- I can "see" GBU, twice & play it direct, but I can't get it into my very restricted actual ringtone list
What's happening here & how do I correcr it?

[Zogzog]

on the root of the SD in a folder named Ringtones ... (or in /Notifications for notification tones .........)

Greg - this isn't an official forum, so calmness is imperative. No one here is paid, or obliged, to help you.

I would recommend looking at the problem methodically. You could join the Cosmo Discord for help, but on my Cosmo, I've never had this issue.

Out of curiosity, is your Cosmo's SD card partitioned as 'internal', or 'portable' storage? Normally, there's a dialogue that appears when you insert a new SD card for the first time.

I doubt this is to do with the Cosmo's software, as old as it may be.

Using the folder on the internal storage would eliminate any potential problems with the SD card. I can't really offer any more help with this though, as I don't use ringtones - I've been vibration-only for a decade =P

[ZimbiX]

If you can't work it out, another thought is that maybe a third-party dialer app would allow ringtone customisation that doesn't depend on the choice in the OS

[ZimbiX]

I just tried in Truecaller, and it has the ability for a custom ringtone

Replying - mainly to Dom @ 19th Sept
Thanks for the advice - esp about "tone"
I think it's an "android" problem on my phone, or a small subset of Cosmo's ....
As I said - I can "see" the ringtone, inside the SD card files
I can play it separately, but I can't get it to play when the phone rings.
As for partitioning ..
Screen / Files / Home / San Disk SD Card / Ringtones / GBU.mp3 ...
But it won't play when the phone rings
BUT: if I go
Screen / Settings / Sound /Phone Ringtones - I'm presented with a VERY LIMITED list, which I think is not the standard "Android" option ??

I cannot tell whether the SD card is internal or portable - how do I find out?
Incidentally, I can find ANOTHER copy of "GBU" in:  ...SanDiskSd card / Download - I appear to be able to Cut or copy it ... but I cannot paste it into "Phone ringtones"... the limited list of ONLY FOUR tones appears to be locked.
