AT&T's LG V40 ThinQ gets Android Pie with April 2019 security patch

Verizon’s LG V40 ThinQ got updated with Android Pie last month
and now AT&T has released the latest version of Android for
this 2018 flagship. The new firmware carries version number
V405UA20d and weighs around 1.5GB in size. It brings Android Pie
niceties, new UI and new navigation to the V40 ThinQ, in addition
to bumping up the Android security patch level on the phone to
April 1, 2019. It’s unclear why an update seeding in June only has
the April patch – it could be that LG is running behind schedule or
AT&T taking too long to approve the release as US carriers
often do….
