[GBtra]

I am not able to locate the voice recordings of year 2016 and 2017.... since that time I have changed my handsets 2 to 3 times but all this while I have used Samsung only.. is there a way to get those recordings back ? Very precious ones .. help will be appreciated

[GBtra]

Yes

[sarnandu]

did you check in download or Audio files

[GBtra]

Yes i did

[sarnandu]

did you back up those files in samsung cloud

[GBtra]

I think not...but doesn't it take the back up by default ?

[sarnandu]

you should do that than you can easily restore that

[GBtra]

Hmm, so what's the way out for this old recording then ?

I had tried backing up call recordings.. but it did not restore in the call logs. Only as mp3 recording files through voice recorder.
