I have to say this again, because of my past experience with Verizon and firmware updates OTA... Expect this process to take not just days or weeks, but maybe a month or two. Seriously.
On every phone I have had, I didn't even GET OTA updates - I usually had to bring the phone into the store, and ask if they had any updates for it. Only THEN did any update occur, and it was by hand, from a tech...
This is when it was well-known and publicized in forums etc. that firmware updates were available OTA in most areas. The servers weren't centralized, and they made it sound like it was tower-to-tower in how they were updated with software. Frankly, unless this process has changed at Verizon's end, OTA updates are just NOT a priority for them - they disperse it as they wish, when they wish, if they wish, and never in a rush. Some areas will get it right away, some weeks from now, and in some backward areas (probably mine) we'll be looking at July of 2020.
Has even one person posted an actual photo of the actual OTA update? All I've seen match the v3 leak - and I'm finding that to be kinda buggy. I hope that's not what everyone's looking forward to.
