This would mean that that it should be arriving by the 1st of February. However according to HTC US product manager Mo Versi, the update for the carrier versions of the One M8 and One M7 have been pushed back by a bit. According to HTC, it seems that there are some issues with the update that have caused the delay.
According to HTC, “We’ve been working hard in the labs with Google and our carrier partners ever since the code release and are making great progress so far, but if you’ve been following the progress of this rollout you will know that Google has had to address several issues with this release. We’ve been diligently working to fix some of them on our end and incorporating Google’s fixes as quickly as possible.”
This is rather unfortunate as HTC has managed to update the non-carrier versions of the HTC One M8 which means there are still a handful of disgruntled HTC users left. However we suppose at least HTC has been upfront with the problems and hopefully carrier versions of the One M8 and One M7 won’t have to wait too long for the update.
