Description bug *

Sometimes, the app does not start recording at all. It happens after the phone is switched on. Some days it works perfectly, some other I have to reboot the phone and try again.
When it does not work, I press the record button and the application get back to its main screen; then I press it again and a popup asks me what to do (I usually select to switch off the app). Starting the app again have the same behaviour until I reboot the phone.
If I use the app and it works normally, no matter how many times I restart it, it works. Once I switch off the phone, I do not know if it will work again.

How to reproduce the bug *

1. start the app
2. press the red button on the bottom left corner of the screen
3. press the same button on the centre of screen, below the sentence you are supposed to record
4. the screen goes white for a short time (about 0.5 seconds) and you are back to the main screen
5. press the red button on the bottom left corner of the screen (again)
6. press the same button on the centre of screen (again)
7. a popup appears. Its title is "L'app CV Project continua a interrompersi". The first option is "Informazioni app", the second option is "Chiudi l'app". Select the second one

Additional context

Oher apps that probably record audio work (e.g. Duolingo, Telegram)

Thank you very much,

Thanks for the reporting. This is very weird 😕 sometimes works sometimes doesn't work.

I'll try to investigate and fix this 😄

[eppesuig]

I have been reading the source code, but do not have any ideas about what is really going wrong. Sorry.

This is a more detailed log, got via adb logcat that probably points to the source problem "no default device defined":

@eppesuig ok, so it looks like a OS bug 🤔
Maybe sometimes a system process is not run and the app can't find the hardware device?
Very weird

[eppesuig]

I opened an issue against the operating system. You may find it here.
Let's see if it is an OS problem.

[Sav22999]

@eppesuig Excellent!
