I’ve been trying to listen to my Samsung T10 whilst its been charging from my PC. For those who have tried, you probably found the message that the USB is connected or that it is charging gets in the way of any constructive listening.
Well, I’ve found a way. Switch the T10 off, unconnected. Switch it on, and whilst it is booting up, connect the USB. This way it does not properly mount to the PC - hence no USB is connected message. However, you might get a charging message. You can get rid of this by sliding the power bar at the side. You then may be able to use the T10 while its connected.
