This is how you do maintenance fixes.

A week after rolling out the Android 7.1.1 update to the Pixel and Pixel XL, Google is now rolling out a new build (NMF26Q) that fixes MMS-related issues on UK's O2.

The changelog for the build includes a single fix aimed at O2 customers:

Remove spaces in front of APN types so that telephony can find APNs that can handle a particular type properly.

As for the LTE issue that prevented a small number of Pixel customers from connecting to Band 4, that particular problem was fixed in last week's update.

It looks like the NMF26Q build will be rolling out shortly, with the factory images and OTA files now live.
