The update will add the new Wi-Fi Hotspot feature to your device, but it will be turned off by default, so you wouldn’t know unless you go to Settings and look for it. In your Settings app, go to the Networks and Connectivity option, and click on Internet Sharing. Once the firmware is updated, you will see a new ‘Wi-Fi Hotspot’ option here, which you can turn on by tapping on it. You will then see the options to change the default name of your Wi-Fi hotspot, just like in a cable Wi-Fi. Change your hotspot name and password, and share your Jio 4G data with friends or your own devices as and when you like. The Wi-Fi Hotspot icon will show up in your phone’s notifications panel once it is turned on.
The update may take some time to reach you, though, because this is an over-the-air (OTA) update and has just begun to roll out. Some users in India have reported getting the update, but many more will get it in the coming days as OTA updates are usually rolled out in batches.
