I was using my phone for tethering yesterday and switched off the option under settings-personal hotspot when i finished. Today i am using my laptop and see the wifi SSID for my phone under the options available. I checked the phone and option is definitely unchecked. So i try to connect to the iPhone SSID and i am connected to the 4G internet through the phone. I reboot the laptop and the phone but the tethering option is always active. I have not seen this before so assume it must be related to my 9.1 update. Anyone else see this.
