Owners of HTC’s flagship, the One, will be happy to hear that the company has just announced that it has released its Android 4.4, KitKat, update to carrier level testing. This means that each service provider who carries the HTC One will now begin testing the update with their devices, and if everything passes, the updates should begin rolling out shortly.
There is no set time limit on carrier testing, and any one of them could reject the update if it does not play well with each network in question. HTC says that certification could come as early as next week, but even so, it could take weeks before the carriers stage an OTA update roll out. Unfortunately, European HTC One owners will have to wait longer for their 4.4 update as HTC had no comment on when it may roll out.
