The LG V20 on T-Mobile has started receiving a new update. Arriving as software version H91810k and weighing in at 147 MB, the update brings the e911 timer fix that has also been rolled out to some other handsets recently.
In addition, the update also includes Android security fixes for the month of May. And finally, as is usually the case, some minor bug-fixes and improvements are there as well. Given the fact that it's an OTA roll out, it might take time for the update to hit your device.
