I have recently purchased an InFocus M512 phone. It runs KitKat (4.4.2).
I have loaded a few apps into the SD card (moved them to SD card after installation).
When I connect a USB Flash disk everything works as expected. When I subsequently unmount it (via settings -> storage -> unmount shared storage) I get the following message:
Unmount SD card? If you unmount the SD card, some apps may be unavailable until you remount the SD card.
When I accept it the USB storage is indeed unmounted (when I physically remove the USB Flash disk it I receive the notification that it was removed, as opposed to a notification that it was removed unexpectedly). The SD card seems to remain mounted - in particular I can access the files in it (via the stock file manager), however I cannot run any apps that I have moved to the SD card - when I press the app shortcut nothing happens. The only way to resolve this is to restart the phone.
If I remove the USB Flash disk without unmounting it, then I get the notification that it was removed unexpectedly (as expected) and afterwards I can run apps residing on the SD card with no problems.
Why unmounting USB storage causes unmount (?) of the SD card?
Is this the expected behavior? Is there anything I can do to fix this?
Thank you for your help.
