Is the internal file automatically deleted?

My app copies external captured photos to internal storage. Gradually or immediately, the file is uploaded to a server in the online world. There are certain cases where the file to be loaded is missing, resulting in a FileNotFoundException. 78% of cases happened in Xiaomi devices.

Is it because of any memory cleaning application? Or is there any solution associated? Even an appreciated view of a possible problem will be appreciated.
