HTC has said that there will be a delay in introducing the latest Android upgrade, KitKat into its flagship phone, the HTC One.

Jason Mackenzie, president of HTC America said in a post on the official website that the mission to push KitKat into HTC One for US and Canada customers within the stipulated 90 days of the software's release will be delayed by one or two weeks.

He also shared that the software is presently undergoing certification phase with all the four carrier partners in North America. He also confirmed that the carrier partners share the same enthusiasm as the company in getting Android 4.4. into HTC One devices.

"That said, the software development process does not always follow a linear path and we know today that we will miss our self-imposed target. The good news is that we won't miss by much as, it shouldn't be more than one to two weeks to complete each of the carrier versions of the HTC One," he said in the post.

However, Android 4.4 KitKat update has already started arriving in Europe for HTC One reported IBTimes. HTC One users from Latvia, Finland, Norway, Romania, the Czech Republic, Russia and Spain have reported that the update is being delivered to their devices.

The update weighs 308MB and will have features and improvements like security enhancements, cloud print service, new Bluetooth profiles, immersive mode, full emoji keyboard, messages/Google handout integration and others.

The report also noted that support for Adobe Flash in HTC's Web browser has been removed as it will not be compatible.
