I’ve noticed the usable memory dropping over time and it appears that the Lumina 920 has a memory leak. 

It looks like memory is being reported as used by ‘Other’ ( Settings \ System \ Phone Storage \ Phone \ Other ), but not ever being flushed once used.

This came to light when I transferred an audio file via Bluetooth to my phone – I listened to it once, but could never get back to the file to replay, nor dictate where the file should be stored for future use.  It looks like the total available memory that was available is being reduced every time a file is transferred.

To test this theory, I did the following:
  Removed the SIM
  Factory Reset the phone
  Turned off wireless
  Turned on BlueTooth
  Paired phone with PC
At this point, the memory assigned to Other = 395.83 MB

I started transferring WAV files to my phone and monitored increases in memory assigned to Other:
  33.3 MB WAV file causes Other to increase to 462.61 ( 2x the file size transferred )
  29.7 MB WAV file causes Other to increase to 522.28 ( 2x the file size transferred )
  48.7 MB WAV file causes Other to increase to 619.73 ( 2x the file size transferred )
  38.1 MB WAV file causes Other to increase to 695.98 ( 2x the file size transferred )

After transferring 4 CDs, and doing nothing else, the memory use of Other went from 0.03 GB to 4.5 GB.

There is no way for the user to clear this and reclaim the available memory except by performing a factory reset and losing all other data.

I’m afraid that over time, I am going to run out of memory, though I am not using very much at all.

How can we rattle Nokia’s cage so they can rattle Microsoft’s cage so the end user doesn’t end up with a phone that can’t do what its suppose to do?

There is no indicator for the amount of memory used, what you are referring to is storage which is quite different.

What happens when you delete the files transferred? Is the space claimed back?

That's just the point - the user cannot delete files that are transferred via BlueTooth - there is no dialogue box to direct where the file should go.  I have been streaming audio files to my phone for the last couple of days and watching the Other storage space grow.  It's now over 11GB - with no apps on the phone other than the default that ship with a 920.  That's 1/3 of the total storage space devoted to data that can't be used.  It is possible that the phone will clear the data once its completely out of space, but I doubt it.

You should be using the Windows Phone software for the PC to move files to the phone.

You don't have to use the software. The drivers for the phone will connect the phone when you connect with USB. Use windows explorer. You can transfer files to the correct folder. Documents. video. ringtones or music

I have no idea where the bluetooth transfers are going. You may not be able to delete them it they don't show up in those folders
