Software update is pushed out to the T-Mobile LG V203
The update weighs in at 88.7MB. When it arrives on your LG V20, make sure that you are connected to a Wi-Fi network before starting the updating process. In addition, you need to charge the battery on the handset up to at least 50% before moving ahead with the update's installation.
Since this is an OTA update, it is sent out on a staggered basis. That means that it can still be a few days before it hits your LG V20. If you're not the patient type, you can try to manually update your handset by going to Settings > General > About phone > Update Center > System update > Check for update.
This might not be the most feature-packed software update, but the security patch is important as is the e911 fix. Make sure you take the opportunity to install the update on your LG V20 as soon as possible.
