MTP bug or feature...?

[OppfinnarJocke]

My phone runs 4.1.2, and only MTP or PTP is available for file transfer. Obviously, PTP is useless for transferring arbitrary files, but MTP seems to work reasonably.

However, I have discovered a strange thing that may be an issue only with my phone, or it may be by design or a plain bug.

So I hook up the phone, select MTP and my W7 recognizes the phone and I can browse the file system. But, if I update a file on the phone, this update is not reflected in W7 Explorer, there the old file is still shown. I have to disconnect and then re-connect the phone for the updated file to be available, and sometimes even that does not work.

I know that the file is updated, because the file manager on the phone shows the new file. But W7 does not see it. This just now caused me a *lot* of wasted time where I thought that I copied the updated file while in fact I did not.

Is this really as it should be?
Seems dysfunctional to me...

And BTW, there are no files in C:\Users\<me>\AppData\Local\Temp\WPDNSE

I tried a couple of things for this ... I use File Explorer on the Android Side and Windows 7 64-Bit on the PC side.

On a Droid Bionic with 4.1.x it behaves the way you describe on both the SD and SD-Ext cards.

On a Droid Maxx with 4.2.x it behaves the way you want. An added file on the phone side is immediately shown on the PC side.

Thanks. I have to wait for 4.2 then...

I definitely think MTP on 4.1 is flawed. I cannot drag a file from the phone to an app on the comp, for instance. Oh, why could we not have the simple mount as USB device option that worked fine?
