I have 2 devices:
Both have the latest version of the Google Play Services.
On connection, the client app is sending some bytes to the server app; depending on those, it will send back bytes or a file. It works on all client devices I have except the Galaxy Tab 3 and I have no idea why. Sending bytes works, but not sending files (file is approx. 25Mo! i've tried 5Kb, same result : Payload Failure). On failing, client disconnects from server and then reconnects to it, only to fail again. After some tries, a pop-up often appears saying Play Services have stopped.
Does anyone have an idea why this is happening on this specific device?
I have some logs from my server app :

And the exception line from the bug report dialog on my client app (dialog doesn't show up every time so I don't know if this is the reason behind the Nearby's failure) :
java.lang.IllegalArgumentException: Requested flags 0x43, but only 0x3 are allowed
This is a bug in Nearby Connection's code! It's an instance of IllegalArgumentException in grantUriPermission on API level 19
I've just submitted a fix, but it'll take roughly a month until it's rolled out to devices.
