i tried it. all.
i have a imac. so ports are ports, i have 4, tried it all.
i have another desktop pc, the same. i have a notebook, the same.

its like a bug, everytime i connect to a pc now i get that msg. and after, states that i can charge. with wall charger, its okay.

Nsu see's it, but keeps saying my phone is connected through usb, were it isnt.
i want to trow it to the trash.

i cannot use fb or twiter nor im getting the update, nor i cant reflash to correct bugs. i feel like i have the most expensive phone and cant use it.

SUCKS BIG.
