T-Mobile has commenced rollout of the Android 5.1.1 update to the entry-level LG Leon and the G Stylo. The OTA updates — clocking in at 316.2MB for the Leon and
428.6 for the G Stylo — bring display and battery life (for Wi-Fi calling) improvements. The 5.1.1 update brings the version number to H34510b on the Leon and H63110b on the G Stylo
The devices made their debut on T-Mobile earlier this year with Android 5.0 on board. You can download the update as long as you're on a Wi-Fi connection and have over 50 percent battery life. If you're rocking either device, be sure to head into your phone's settings to download the OTA update.
