Hello there,
We carry out protected butterfly population samplings using an Android (MIUI Global 12.5.5; Redmi Note8) smartphone. For data input we use ODK application (v2024.2.1). Recently we could not upload them to the ONA server (Error: Generic Exception: Error: (402) at https://odk.ona.io/submission?deviceID=collect%3AOzviZYVKSYYNrMa9) (the solution just found in help center page, MANY THANKS!!).
Unfortunately, somehow during fieldwork the cell phone kept in my shirt pocket "activated" itself and the running ODK application selected and then deleted (700 records) the not yet uploaded data (probably some button was pressed).
I can't find the data in Internal Storage -> Android -> org.odk.collect.android ->
files -> projects -> abcc84a2-cfc4-41ae-8536-5c9a71a1c743 -> instances. As far as I understood the form data stored in xml and each data is a separate xml file.  
I searched for but couldn't find the bin. The question is what can be done in this case?
Many thanks in before hand
Laszlo

Hello Laszlo,


Please note that if you delete data from ODK collect directory, there is no way you can recover it since it does not have deletion bin where you can restore data. Cases we have encountered before is when the user factory resets the device, or when the user manually deletes all data from ODK Collect, both saved records and finalized record. This can not be recovered or tracked as it is stored on the local device memory. We can only track records submitted to the server.


Regards,
Samson

Dear Samson,
Thank you for your reply. Based on my fatal experience in the course of future ODK development, it would be advisable to store it also on the phone's memory card.
Best wishes
László
