My S3 (Jellybean) was suddenly no longer recognised by my PC when plugged in via USB. I solved that by debugging using Developer OptionsDeveloper Options as advised in another thread, which allowed the driver to be installed... again (thank you). But
But now if I try to use it as a hotspothot-spot via USB tethering, I'm prompted to enter a network security key. Previously
Previously it just connected without the need for this and furthermore, I don't know where I would find such a key since I didn't set it up in the first place. Help
Help anyone?
