LG V30 receiving Android 8.0 Oreo update at AT&T
Along with Android 8.0 Oreo, the update includes the March security update, just like Sprint's version. Since Verizon deployed the update much earlier this month, it included the February patch. Besides that, LG included other security updates such as Meltdown and Spectre mitigation patches.
In any case, if you're using AT&T's LG V30, then you should know the update weighs in at 1.8GB, so make sure you have enough free storage on your phone.
Now that AT&T is updating its LG V30 to Android 8.0 Oreo, T-Mobile remains the last major US carrier that has yet to release it. Hopefully, those who decided to go for T-Mobile's LG V30 will receive the same treatment sooner rather than later.
