For me, one of the greatest features of the smartphone is the ability to tether out a connection to a computer, laptop, tablet, or any other compatible Wi-Fi or Bluetooth-enabled device. When on-the-fly, it means I don't have to waste any time sourcing a decent hotspot, and can instead get on with the task in hand. While most smartphones offer this feature natively though, often it is hidden which means you can often browse the Web on your smartphone, but cannot replicate the experience on your external device. Hotspot Control from Chainfire is a nifty little app which will enable (or indeed disable) the hotspot feature of your Android, and so if you've been having trouble accessing your hotspot settings, you may want to give it a try.
