HTC Customers and Enthusiasts,
HTC is excited about the new features in Android L release and we canít wait to share them with you. We are committed to updating our flagship HTC One family as fast as possible as part of our HTC Advantage program. We will begin rolling out updates to the HTC One (M8) and HTC One (M7) worldwide within 90 days of receiving final software from Google, followed shortly thereafter by other One family members and select devices. HTC Advantage protects your smartphone investment, ensuring you have the best smartphone experience long after purchase.
