We can see that the first option says, "Portable WiFi hotspot"
What we're going to show in this video is how to make our HTC One M8 a portable WiFi hotspot, which that means is that we can make our phone a hotspot and connect our computer to it, allowing us to use the Internet on our computer through our phone. It's a very useful feature, and one that we can show how to do now. We can add and use up to five devices on our WiFi hotspot when we're creating a portable WiFi hotspot. To do this then, all we need to do is to turn the option on. We can see that there is an icon on the right-hand side of the phone, and right now it says the word "Off".
We can see that it's very simple and we can now connect via WiFi, we can connect to our phone with our computer, in order to use the Internet
If we want to turn this function off, and it's good to do that because we only want to turn it on when we're actually using it. It does use a lot of battery life, so make sure this is turned off when this function isn't being used.
