Android environment programs cannot create any files on external storage (SD Card)

On 4.6.0.13 while I am able to create files with the Steps to reproduce, two of my Android apps can’t create files on the SD card

  • DIE ZEIT E-Paper App (de.zeit.diezeit.epaper.android)

  • Schwäbische E-Paper App (de.schwaebische.epaper)

For both apps it is the same behavior: When switching from internal storage to SD, all files already downloaded are moved to SD, but when downloading new files directly to SD, only directories are created.

I forgot to mention: I switched from Xperia XA2 to Xperia 10 III, while Sailfish OS 4.5 was the actual version. The same versions of Sailfish and Android apps, that worked on the XA2, had that strange behaviour from the beginning in the 10 III.
