The latest Android 4.4.3 KitKat update is now rolling out to HTC One M8 users in Malaysia. It is over 650MB in size and we recommend updating the software using WiFi.
Apart from the usual security and stability updates, the software also improves the One M8’s wireless connectivity as well as tweaks to its native apps including Camera, Gallery and Settings. If you haven’t received any notification, you can check manually at Settings > About > Software on your phone.
