HTCis continuing to roll out itsAndroid 6.0 Marshmallowbuilds for its flagship smartphones this year. We have seen an update land in Asia and North America so far, and today the company has announced that the latest version of Android will be making its way out toHTC One M8customers living in the UK very soon.
According to the company’s official UK Twitter account, the Marshmallow update will begin rolling out for the One M8 in the UK sometime within the next 48 hours.One M9customers need not fret either, the company says that a similar update is on the way for its latest flagship “shortly”, although we don’t have an exact time frame. Presumably this update is for unlocked models. Any carrier branded smartphones will have to wait longer for network providers to bundle their software in with the update as well.
It may be a little odd that the M8 seems to be ahead of the M9, but this has been the case in a number of countries so far. The updates we have seen so far have weighed it just over 1GB but contain the new definable app permissions, Doze battery optimizations, and Now on Tap Android features, as well as some of HTC’s own apps and tweaks.
UK customers should keep an eye out for that over-the-air update notification in the next couple of days.
