Verizon has released system update number 8 for LG K51, whereas the LG Q70 is receiving its 7th system update. Regardless of the different system update numbers, it does not bring more than just a new security patch. The new update for Verizon-bound LG K51 and LG Q70 carries software versions  K500UM10k and  Q620VA10i respectively. If you’re a LG K51 or Q70 user on Verizon’s network, then you might have already received the new build. If you haven’t, then manually update your phone by navigating to Settings » About phone » Software updates » Check for Update and then tap on Download Now button.  [source 1, 2]
