HTC said it will miss its self-imposed deadline of updating the One within 90 days from the time Google released Android 4..
KitKat. It originally committed to giving the One the latest version of Android by the end of January. According to HTC, KitKat is now undergoing carrier testing with AT&T, Sprint, T-Mobile, and Verizon Wireless. Though it will fall short of the 90-day cutoff, HTC expects the update will take only another week or two to complete for each carrier.
HTC asked customers for patience as it finalizes the system update. More information should be available soon.
