After Kit Kat was announced, HTC went on record saying they would "deliver Android 4.4 with Sense 5.5 for the HTC One within 90 days." For reference, that statement was issued the same day Kit Kat was announced, on October 31, 2013. And as we draw ever so closer to the 90 day mark, HTC has issued another statement with mention of how they "are getting closer to delivering KitKat and the finish line is becoming more clear."
Simply put, with a few market exceptions, Android 4.4 is not yet rolling out for HTC One users. HTC did say the update is already rolling out for those in the Nordics, Eastern Europe, Turkey, Ukraine, Middle East and North Africa regions. That came with the promise about how more markets are "set to follow."
Getting back to this most recent statement though, the 90 day comment referred specifically to those in the US and Canada. HTC talked about how they have "done 'ok' with software updates" and went as far as saying they also "recognize that 'ok' is not good enough." This brings them to something we have recently seen -- the HTC Software Update page.
As we recently learned the US updates have reached the carrier certification level. This applied to AT&T and T-Mobile as well as Verizon Wireless and Sprint. Anyway, according to Jason Mackenzie, President, HTC Americas, the "software development process does not always follow a linear path and we know today that we will miss our self-imposed target."
Simply put, HTC will be missing that 90 day window. But trying to keep this more on the positive side, Mackenzie also touched on how the "good news is that we [they] won’t miss by much." It was said the delay "shouldn’t be more than one to two weeks."
