Problem with samsung's Voice recorder

I have Samsung Galaxy f12. It has a Voice recorder which was pre installed from Galaxy store. I had a software update 4 days ago and my Voice recorder is also updated.

I access it a lot and recently it is having problems. I access it mostly thru the lockscreen shortcut. I press the record button then record the stuff but when I press the save button it doesnt save the recording for a few seconds to minutes. It stops the recording but then it looks more like it froze with the play/pause button,save button and recording timer still visible. Then it closes the recording and goes back to being a big red button which we are supposed to press for a new rec, but it doesnt show me the usual pop up message on the bottom of the screen saying that my voice recording is saved as this name etc etc.

I did 5 recs tonight. When i went to check in my recorded stuff i saw nothing until a few mins when it saved the last 2 recordings only after showing this message "recording stopped suddenly. Recording is now saved as xxx" or smth like that. I cant see my past 3 recs in the folders/albums of saved recs.

I even opened the app itself and recorded thru it but the same problem persisted.

I just want to know how and why this happened and will i get my recs back through any way?? Also what can i do to prevent it? I have cleared the cache too, i have kept it updated always but still this happened.
