OK.... There were a couple of recent updates... MMB29V was the first one, the security update that everyone jumped on.
Then the N Preview dropped and everyone went "SQUIRREL!!!" and went and paid attention to that. But soon after N dropped, another image popped up, MHC19I. Now, some things to note about this one... First, the build name. It isn't in line with the MMB29 builds that we were on since the 6.0.1 first dropped. Those other builds were mostly security fixes, etc... Now, the name preface changed to MHC19... which is the same as the 'big' update to the 5X builds as well.
The bootloader and radios were updated to the newer version that we saw in the N Preview.... THIS is the update that Franco is referring to. So I'm curious how things shake out to be honest. Unlike the 5X, I can't really point to any performance/stability/anything issues on the 6P... thing runs great, rarely has a FC, nevermind a reboot. Things like the camera are fast (I can get from screen off to taking a focused pic in a tick under 1.5s). So I wonder how they'd make an already great running phone run greater...
We'll see... I'm booting as we speak.
