USB 3.0 is still going through some growing pains. As you can see above, the Note 3 won't let you keep USB 3.0 on all the time. You have to enable it just before your transfer, and it will automatically disable itself after four minutes of inactivity. Every time you plug in the Note 3, you have to go to the settings and turn on USB 3.0 or you will transfer at 2.0 speeds. The above dialog box also gives the alarming warning that your radios may stop working due to interference with USB 3.0. Congrats to Samsung for being the first out the door with this feature, but it looks like there are still some bugs to work out.via Review: The Galaxy Note 3 is big—and it pulls some benchmark shenanigans | Ars Technica.
