Hey! I had this problem when I am using personal hotspot. Firstly, personal hotspot is off. I supposed when I turned it on, it will show me whether to turn on my Bluetooth or turn on my wifi and usb. What actually happen is, when I turned on my personal hotspot, it didn't show me the option to turn on my Bluetooth or turn on my wifi and usb, it just simply turns it on (Bluetooth was turned off). Next is, I try to turned off my wifi, with Bluetooth off too. I went to turn on my personal hotspot, instead of showing 2 option of "Turn on Bluetooth" or "Turn on Wi-Fi and USB", it showed me "Turn on USB" and "Turn on Bluetooth and Wi-Fi. Anyone mind helping me on this or do I really need to do a reset Network Settings?
