Phone software updates From time to time, software updates for your phone may be available. Your phone can check and then notify you if there is a new update. You can then download and install the software update using your phone’s Wi-Fi or data connection. You can also manually check if there's an available software update for your phone.
You can check the version of Software on your handset by following the below steps:
1. Tap the Menu > Settings > Then scroll down to ‘About Phone’ and tap on it > Then tap on ‘Software Information’.
This will give you a detailed info about the current software on your HTC Device.
