Good news, Zenfone users!

ASUS Philippines has officially announced that they are rolling out the OTA KitKat update for the Zenfone 4, 5 and 6. The KitKat update delivers new functionality to the already awesome devices, including a Do Not Disturb mode, Reply via Call-in SIM card (system will auto select the right phone number via the call), as well as full dual-standby with two SIMs.

The KitKat update is a big one, weighing in at more than 450MB, so you might want to connect to WiFi before attempting to grab the update. Interested in the Zenfone 5? Read our review here.
