Google doesn\'t like local file transfers, because that enables

Android, and all the standard file transfer apps are so crap.

That doesn\'t make sense. You can do any file transfer with a PC
and slave Android. I prefer to transfer from PC anyway, even will
another USB stick on the PC.

Oh, it makes sense, all right. You can\'t install an application
with \'file transfer\' because you can\'t access the directory where
apps reside. You can\'t even inspect the filesystem except within
a walled-off area (try, for instance, to find a fonts folder, or a
picture file from a text message).

Maybe there\'s developer tools that can explore the walled
garden...

Yeah, one has to have a \"fully jailbroke\" phone to get access to
those areas, but some carriers do not allow such \'behavior\'.

I have a phone I never used that had two sim card slots in it and
Verizon would not put it on their plan or system. I was so pissed.
It is for folks that travel to Europe a lot or Israel. No need to
switch phones or have two or any of that nonsense. I still want to
get it and see if ATT will let me use it. It is only about 5 years
old now, but it was a top notch \"Viewsonic\" phine. I don\'t know if
they are still is or ever got going in the cell phone world, but it
was cool for its time.

Why would you stick a communicative USB port on a
battery-operated device and then restrict it from
acting as a USB host?

Is this normal?

Is this sane?

I know there are a multitude of other methods of
com available for these devices, but why not
simple USB stick transfer?

OK - I finally found a micro-usb 3 to USB adapter with
the correct pin grounded (connection between ground and
adjacent \'I/O\' pin, NOT the center pin)

With this usb pin connection, the TAB 8 reads memory
sticks on the usb port without system setting adjustments.
It just recognizes the connecting - flags a notice to
the user and opens the drive when the notice is tapped
(maybe tapped a few times - hard to tell with this screen).

All the other micro-usb hardware I had was missing this
connection. I asked Mohamed at the cell phone shop
next door to keep an eye out for one. His supplier had
just that - one adapter. Now it\'s mine. Nobody else
can have it.

I actually went through a couple of places checking to
see if ANY of their micro-usb connectors or peripherals
had this connection. (have socket with pin sensors
attached) NADA.

So when someone says it\'s USB OTG, measure it.

Might be worth kludging the contact permanently if ever
the TAB 8 is in the shop for battery, screen or other
repairs.

but then it can\'t be a device anymore so you can\'t connect it to a PC

Or you can just open the Google Files app, or whatever other file
manager you prefer.

Yeah, well, finding files after transfer is another
issue.

Files and folders don\'t seem to show repeatable
navigation - dependent on where listed and
how approached in the GUI

Isn\'t a tab 8 about 8 years old?

Also some chip reader/usb port devices do not mandshake nicely in
every case.

As old as I remember those being, that may have been back in the
virus on a stick days. So they put extra security in. No connection
is as secure as it gets, eh?
