Yesterday we heard that the Nexus 5X received a software update and now it is the turn of the Nexus 6P, which is getting an update with performance enhancements.
The Nexus 6P software update brings the same performance improvements to the handset as the 5X one, it comes with the build number MHC191, the news of the update was posted on Reddit and you can see what is included below.
The fixes for this build are similar to the ones I mentioned for the 5X. Some of the fixes will help with and address:
General device performance
DND next alarm disappearing issue
Carrier-specific bug fixes
I also should mention that the builds mentioned on the developers site are carrier specific, with the majority of carriers worldwide being on MHC19I (5X equivalent – MHC19J).
The update should be available shortly as an over the air update, Google has also released a system image which is available on their developers website.
