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.

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. RL

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 RL
